PROBLEM TO BE SOLVED: To provide a liquid seal type vibration damper capable of obtaining stable dynamic characteristics by suppressing a variation in cross-sectional area of an orifice. SOLUTION: A lip part 53 for a third orifice is formed at the farthest edge part on the ridge line side where the outer peripheral face 43a of a third back face rubber part 43 crosses with an orifice wall 93a of the third orifice 93 on the outer peripheral face 43a of the third back face rubber part 43. By this, it is possible to avoid the formation of a gap between an intermediate cylinder 10 and an outer cylinder 32 near the orifice wall 93a. Thus, the orifice wall 93a can be firmly fixed between the intermediate cylinder 10 and the outer cylinder 32 to that extent. As a result, it is possible to obtain the stable dynamic characteristics by suppressing a variation in the width (the cross-sectional area) of the orifice. COPYRIGHT: (C)2006,JPO&NCIPI |
