1. A damper that is attached to a pair of members approaching or separating from each other and gives a damping force when the pair of members approaches or separates from each other, comprising:
a tubular cylinder that has an opening formed at its end portion and is connected to one of the pair of members;
a rod that is movably inserted from its tip through the opening of the cylinder; and
a cap that is attached to the opening of the cylinder and prevents the rod from slipping off from the opening of the cylinder, wherein
the rod has a piston on its tip side and a mounting portion mounted on the other of the pair of members on its base end side,
the cap has a main body that extends in an axial direction of the rod, and the main body is formed with a receiving opening that can receive the rod from an outside in a radial direction thereof,
the cap includes a pair of half-split members having a half-split cylindrical shape, and has a locking unit capable of locking the pair of half-split members to each other when assembled into a cylindrical shape, and
the locking unit is configured to lock the pair of half-split members so that they can be separated from each other by a predetermined distance, and is configured such that when the rod maximally moves in a withdrawal direction with respect to the cylinder, the rod contacts an inner circumference of the cap and the cap increases in diameter.
