A piston section includes a valve seat 30 that forms a first compression-side oil path 32 through which oil flows in accordance with relative movement of a piston rod 21 against a first cylinder, a first compression-side valve section 40 that performs opening-closing of the first compression-side oil path 32 of the valve seat 30, an inner annular section 34 annularly formed as projecting in the axial direction of the valve seat 30 from the valve seat 30 toward the first compression-side valve 40, and an extending section 35 that extends in the radial direction of the valve seat 30 from an outer side of the inner annular section 34 to a position at the inner side from a second oil path opening 322 of the first compression-side oil path 32 and projects in the axial direction from the valve seat 30 toward the first compression-side valve section 40. |
