Abstract

PURPOSE: To reduce any variation in damping effect following a temperature variation by inserting a viscoelastic member between a elastic sheet member made of metal and an arresting sheet member made of resin.
CONSTITUTION: A damping sheet spring 11 is constituted by inserting a viscoelastic material 13 between an elastic sheet 12 and an arresting sheet 14 and bonding them together. The elastic sheet 12 is made of a stainless steel sheet or a beryllium copper sheet having thickness of several hundreds microns, the viscoelastic member 13 is made of silicone based rubber, etc., whose thickness is several hundreds microns, and the arresting sheet 14 is made of resin such as polycarbonate, etc., whose thickness is several hundreds microns. Although the viscoelastic member 13 performs vibratory absorbing action at the normal temperature when vibration is transmitted, damping constant decreases at a low temperature, and inversely, damping constant of the arresting sheet 14 rises at a low temperature. Therefore, any vibration of damping constant due to a temperature change is little as the whole of a sheet spring.
