A door opening/closing device (1) comprising: an actuator (2) having a housing (6) and a driving part (3) projecting from the housing (6); a bracket (12) provided on the housing (6); a detected part (32) provided on either one of the bracket (12) or the driving part (3); and a detection part (20) provided on the other side of the bracket (12) or the driving part (3), which is provided so as to face the detected part (32), and is capable of detecting a rotational position of the driving part (3).

2. The door opening/closing device (1) as claimed in claim 1, wherein the driving part comprises an output shaft (3) of the actuator (2), a lever (4) fixed to the output shaft (3), a link (5) provided between a vehicle body (VB) and the lever (4), and the detected part (32) or the detection part (20) is provided on either one of the output shaft (3) or the lever (4).

3. The door opening/closing device (1) as claimed in claim 2, wherein the detected part (32) is a magnet (32) fixed to the end face of the output shaft (3), and the detection part (20) is a magnetic position detection sensor (20) mounted on a substrate (18) attached to the bracket (12).

4. The door opening/closing device (1) as claimed in claim 3, further comprising a magnet holder (27) integrally attached to the end portion of the output shaft (3), wherein the magnet holder (27) comprises: an attachment base (28) fixed to the output shaft (3) and having a flange (28b) for preventing the lever (4) from coming off in an axial direction, and a hold portion (29) attached to the attachment base (28) and holding the magnet (32).

5. The door opening/closing device (1) as claimed in claim 3, wherein the bracket (12) is provided with a cover (19) that covers the substrate (18), and the bracket (12) is arranged so as to cover an upper side of the substrate (18) in a state that the door opening/closing device (1) is attached to the door.

6. The door opening/closing device (1) as claimed in claim 3, wherein the bracket (12) is configured to rotatably support the output shaft (3) while covering the magnet (32) and accommodate the substrate (18).
