Unit Brake
Abstract: This unit brake which is equipped with a cylinder apparatus in which a clutch mechanism that switches between transmitting or cutting off a biasing force of a spring brake part is disposed is capable of preventing a braking force due to the spring brake part from unintentionally decreasing due to a meshing section of the clutch mechanism disengaging and is of a size that can replace an existing unit brake and maintains the performance of bearings in the clutch mechanism even with long term use. The clutch mechanism of the unit brake (100) comprises: a nut member (81) that rotatably screws on a spindle (50) that is positioned in an area that communicates with the atmosphere and is movably supported in a direction opposite to braking; a clutch (84) that is disposed in a direction opposite to braking with respect to the nut member (81) and faces the nut member (81) in the vicinity of the spindle (50); a clutch box (82) that is formed in a cylinder shape and houses the nut member (81) and clutch (84) on the inside; and bearings (83) that rotatably support the nut member (81) on the inside of the clutch box (82).
