description PROBLEM TO BE SOLVED: To prevent the turn of a nut without deforming: the screw portion of a nut for restricting the axial movement of a bearing rotatably supporting a drum in a planetary reduction gear mechanism, and the thread of a screw portion of a housing of a hydraulic motor to which the screw portion of the nut is threaded. SOLUTION: Protruded portions 3C neighboring each other are provided on the end face 3E of a cylindrical portion 3A of the housing 3 forming the body of the hydraulic motor 2. Hole portions 40A, 40B engage therewith, respectively, and a tongue portion 40C is inserted into a cutout portion 9A of the nut 9. On the end face 3E of the cylindrical portion 3A of the housing 3, a stopper plate 40 is provided which is mounted to be held between the end face 3E and the side face of a planetary gear 12 mounted on the protruded portions 3C.
