Further, when the lock member 45 swings at a predetermined angle, the connection piece 45c abuts on the stopper pin 48. Thus, the swinging operation of the lock member 45 is stopped.
[0063]
　At this time, the upper end of the vertical direction of the lock piece 45a is arranged above the vertical direction than the first cam piece 35 of the cam member 21. Furthermore, the locking piece 45a is disposed on the downstream side of the locking direction (counterclockwise direction) in the first cam piece 35.
[0064]
　The end portion of the unlocking direction (clockwise direction) side of the first cam piece 35 abuts against the restricting piece 27, the end portion of the locking direction (counterclockwise direction) side of the first cam piece 35 abuts on the lock piece 45a contact. Therefore, rotation of the rotation locking direction of the unlocking direction of the cam member 21 are both restricted, the cam member 21 is held by the restricting piece 27 and the locking piece 45a in the unlocked state. Moreover, since it is held by the cam member 21 unlocked state, also the rocking operation of the switching movable portion 42 is held at the detection switch 23, it is not switched on and off of the electrical contacts.
[0065]
　Thus, in a state of being opened rescue door 11, prevents the cam member 21 is cam member 21 is rotated in the locking direction against the intention of the operator, the electrical contacts of the on-off of the detection switch 23 is switched be able to. As a result, it is possible to maintain in a state of being banned lifting operation of the car 120, it is possible to improve the safety of the rescue operation.
[0066]
　Further, when the rescue operation is completed, the operator, as shown in FIG. 4, the rescue door 11 via the hinge portion 12 is rotated to close the emergency rescue opening 3. At this time, as shown in FIG. 9, the contact piece 45b of the lock member 45 abuts against the panel plate 2B. Therefore, the locking member 45 against the biasing force of the biasing spring 47, swings so as locking piece 45a is lowered toward the vertical downward. The lock piece 45a is disposed vertically lower than the first cam piece 35.
[0067]
　Then, the operator operates the grip portion 28 to rotate the cam member 21 in the locking direction (counterclockwise direction). Thus, as shown in FIGS. 5 and 6, the first cam piece 35 enters vertically below the engagement member 25, engagement member 25 and the first cam piece 35 is engaged. Therefore, rotation of the opening direction of the rescue door 11 is restricted by the engagement member 25 and the first cam piece 35, locking device 13 is locked. Also, the corners of the outer edge portion of the first cam piece 35, which is formed in a tapered shape, upon rotation of the cam member 21 in the locking direction, smoothly first cam piece 35 below the engagement member 25 it is possible to put a.
[0068]
　By the cam member 21 is rotated, the pressing of the roller portion 43 of the detection switch 23 in the second cam piece 36 is released. Therefore, switching the movable portion 42 of the detection switch 23, from the state shown in FIGS. 8 and 10, swings to the state shown in FIG. 5 by the holding force of the urging member (not shown). Thus, it switched ON and OFF of the electrical contacts of the main body portion 41. The main body portion 41, when the electrical contact is switched, outputs a switching signal to the control unit 190 (see FIG. 1). Then, the control unit 190 receives the switching signal, to allow the driving of the hoisting machine 100, is allowed to vertical movement of the car 120. As a result, the car 120 is capable of lifting state.
[0069]
　In addition, by the third cam piece 37 of the cam member 21 comes into contact with the roller 43, rotation of the cam member 21 is restricted. Further, the guide pin 26, with the rotation of the cam member 21, disengaged from the second guide hole 39, fitted in the first guide hole 38. The click feeling and the click sound generated during this, that the locking device 13 is locked can be informed to the operator. Thus, the rescue operation using very rescue port device 10 is completed.
[0070]
　The present invention is not intended to be limited to the embodiments described above and illustrated in and drawings, and various modifications are possible without departing from the scope and spirit of the invention as claimed. For example, in the above described embodiments, an example has been described for regulating the swing motion of the lock member 45 by the contact piece 45b abuts the panel board 2B, but is not limited thereto.
[0071]
　For example, the lock piece 45a of the locking member 45 by making contact with the first cam piece 35 of the cam member 21 in the locked state, may restrict the swing motion of the locking member 45. In this case, upon rotating the cam member 21 is unlocked direction, since the vertical direction of the upper locking piece 45a is released, it is possible to swing the lock member 45. As a result, it is possible to restrict the rotation of the cam member 21 before opening the rescue door 11.
[0072]
　Also, the car having the above structure has no machine room into the elevator shaft, may be applied to a so-called machine room-less elevator.
[0073]
　In the present specification, it was used words such as "parallel" and "orthogonal", which are not intended to mean only the exact "parallel" and "orthogonal" includes a "parallel" and "orthogonal" , in the range that can further exert its function may be in the form of "substantially parallel" and "substantially perpendicular".
