れ、コストが高くなるという問題があった。[Problems to be Solved by the Invention] When mounting a power cylinder on an axle, it is customary to mount it with two fixing bolts for each cylinder bracket. In particular, since the turning angle of the wheel cannot be obtained due to poor precision in the direction of expansion and contraction, as shown by the imaginary line in FIG. 4, the knock pin 13 is protruded from the mounting surface 3b of the cylinder bracket 4 or the fixing bolt is fixed. 11 uses a reamer bolt to increase the mounting accuracy. However, installation of the dowel pin 13 and processing of the pin hole 14 require labor and labor, and also in the case of a reamer bolt, processing accuracy is required and the cost is increased.
