ABSTRACT:
A damper includes a hollow outer elongated body formed of a cylindrical member; a hollow inner elongated body similarly formed of a cylindrical member; a viscous body disposed in a cylindrical gap between an inner surface of the elongated body and an outer surface of the elongated body in such a manner as to be in contact with the inner surface and the outer surface of these elongated bodies, respectively; rectangular attaching plate members which are respectively secured to a closed-side other end portion, in an axial direction, of the elongated body having one end portion on an open end side and to a closed-side one end portion of the elongated body, respectively; and a holding structure for holding the gap between the inner surface of the elongated body at the one end portion of the elongated body and the outer surface of the elongated body.
