Abstract
An elastic member made of rubber which urges a coil portion toward a cover is formed into a shape such that the elastic member can be deformed by bending. A rate of change in reaction force of the elastic member with respect to an amount of deformation in a bending deformation region is less than a case where the elastic member is subject to compressive deformation. Therefore, even in the case where the amount of deformation of the elastic member increases due to dimensional variation of a component part, the reaction force of the elastic member does not become excessively large.
