ABSTRACT:
A small-sized damper is provided which enables to effectively vary the damping force of a damper even in a region in which the moving speed of a rod is small. On one of a damper main body and a rod which is inserted into the damper main body, there are mounted a magnet coil having a winding axial line which is coaxial with the damper, and magnetizable attracting members. By electric charging to the magnet coil, the magnetizable attracting members are attracted into contact with the other of the damper main body and the rod.
