PURPOSE:To avoid the transmission of impacts and vibrations to a carriage plate by forming plural projected streaks having the thickness reduced toward the tip part respectively to a vibration absorbing member attached to the carriage plate or a holder and securing the contacts among those streaks and the cylindrical surface of a contact member attached to the other one of said carriage plate and holder so that the deformation rates of the projected streaks are reduced against a large amplitude. CONSTITUTION:A damper consists of two pieces, i.e., an outer cylinder part 55 attached to a holder 25 and an inner cylinder part 56 having a center hole into which a projected shaft 32a of a carriage plate 32 is put. Several projected streaks 56a, having the thickness reduced toward the tip part respectively are provided radially around the center hole of the part 56. The tip of a projected streak 56 touches the inner circumferential face of the part 55. When the external vibrations or impacts are applied to the holder 25, even the root of each streak 56a is deformed as the amplitude is increased. Thus the attenuating capacity is secured even to the vibrations and impacts of large amplitude and not transmitted directly to the plate 32. |
