Then, the pedal shaft 2 is inserted into the shaft hole 6 from the bearing housing recess 7a side. Next, the sliding body 4 is screwed onto the threaded portion 3 of the pedal shaft 2 protruding into the bearing housing recess 7b and tightened, so that the sliding body 4 and the concave arc-shaped surfaces 9a, 9b of the pedal shaft 2 are fixed to the bearing 5a. , 5b are brought into sliding contact with the protrusions 11, 11, . If the tightening force of the sliding contact body 4 at this time is too strong, the rotation of the pedal body 1 will be slow, and if it is too weak, there will be play in the same rotation, so it is necessary to adjust the tightening force to an intermediate strength. In addition to the sliding body 4, a washer 13 and a nut 14 are attached to the threaded portion 3 of the pedal shaft 2, and these are for preventing the sliding body 4 from loosening.
Further, a cab 15 is fitted into the bearing housing recess 7b.
