Abstract
A piston includes a body of a cylindrical shape and a seat protruding axially from an axial end face of the body. The body includes first through-holes and second through-holes axially extending through the body. The seat allows a planar valve to be seated thereon and includes: bottom surfaces each including an opening for a through-hole formed at a position facing the corresponding first through-hole; a seating surface provided around each bottom surface so as to protrude from the bottom surface; and intermediate portions provided between the end face and the seating surface. The seating surface allows the valve to be seated thereon.
