A piston main body (13) in a piston assembly (10A) of a fluid pressure cylinder (11) has a first piston member (40) and a second piston member (42) composed of a plate-shaped member. The first piston member (40) and the second piston member (42) are joined in a state overlapping in the axial direction of a piston rod (15). The second piston member (42) is not provided with a hole that passes through in the plate thickness direction. |
