PROBLEM TO BE SOLVED: To obtain a large deformation stroke of a pressure spring by extending a pressure member in the direction intersecting the pressurizing direction of a contact body and bringing the pressure member into surface contact with the pressure receiving part of contact body thereby imparting a pressurizing force to the contact body. SOLUTION: The upper surface at the pressure receiving part 20b of a contact member, i.e., a moving body 20, is brought into contact, at the inner diametral part thereof, with the outside end part of a pressure spring 7 disposed on a rubber 6 mounted on a tapered surface inclining radially. The tapered surface and the pressure spring 7 are arranged in parallel while setting the inclination angle of tapered surface approximately equal to the flexure angle of pressure spring 7 which is then brought into surface contact, at the outside end part thereof, with the rubber 6 thus distributing the pressurizing force almost uniformly over the entire part thereof mounted on the tapered surface. This structure can produce a large deformation stroke of the pressure spring 7. |
