Abstract

A shock absorber includes a shock absorbing member being to be rotated around an axis and having an outer circumferential surface being in contact with an end portion of a member that moves back and forth with respect to the shock absorbing member, the shock absorbing member having at least one of elasticity and viscosity against an movement of the member, each of the elasticity and viscosity changing in accordance with a rotation angle of the shock absorbing member around the axis, and a device that changes the rotation angle of the shock absorbing member to adjust at least one of the elasticity and the viscosity against the member.
