Abstract
A piston damper has a cylinder including an attachment portion; a piston reciprocatingly disposed inside the cylinder; and a rod including an attachment portion that is moved synchronously with the piston. Each of the attachment portions of the cylinder and the rod is adapted to connect to different one of a first member and a second member to damp a movement of the other member relative to one member among both the members. At least one of the attachment portion of the cylinder and the attachment portion of the rod is formed with a fitting hole, and the attachment portion is axially supported in a fitted state between the fitting hole and an axis relative to at least one of the first member and the second member, and includes an urging device absorbing looseness of the fitting hole relative to the axis.
