Abstract

A power transmitting apparatus comprises a housing having an opening at its end surface in the longitudinal direction thereof to be closed by a cover member (33), which supports an end of a brake support shaft (60) rotatably supporting a brake shoe (61). A hydraulic cylinder (63) for operation the brake is detachably attached to a side wall of the housing. A piston (64) of the hydraulic cylinder contacts with a free end of the brake shoe. The cover member also supports ends of a clutch shaft (26) and a PTO shaft (29), while a clutch housing (38) of a PTO clutch (27) is provided on the clutch shaft so as to be braked by the brake shoe in the state of the PTO clutch disengaged, thereby constituting a subassembly. By attaching the cover member to the end surface of the housing so as to close the opening, all the brake support shaft, the clutch shaft and the PTO shaft supported by the cover member are installed in the housing.
