The first and second bearing housings comprises first and second bearing retaining sections (60a,61a) and first and second mounting sections (60b,61b), respectively. The first and second mounting sections are disposed in alignment with the first and second bearing retaining sections (60a,61a), respectively, and non-rotatably mounted on axial ends of the hanger part (29). The bearings are retained in the bearing retaining sections separately. The crank axle (54) is rotatably supported by the first and second bearings with a crank (52) mounted on an end portion thereof, which presses the first and second bearings. The fixed member (56) is disposed on the crank axle (54) between the crank and the first bearing, and arranged to be selectively released from and fastened to the crank axle.
