A piston includes a disc formed to have an annular shape, a cylindrical skirt portion that projects from an outer peripheral portion of the disc on one end side in an axial direction of the disc, and a passage that is formed in the disc and that is opened on an inner side of the skirt portion. An inner peripheral surface of the skirt portion is a slope that increases its diameter toward a side opposite to the disc.
