Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To exhibit the stopper function during a large earthquake by setting a pressing force in an inoperable mode in a vibration stroke range allowable to a vibrating body in a overlapped part of a sliding member, and giving a pressing force of the magnitude to suppress the vibration in a limiting part of the vibration stroke.
