Japanese Patent JP3047501
Kind Code:
B2
Abstract:
A cylindrical damping bushing for securing a rod-shaped vibrating body to a base. The bushing includes a cylindrical vibration-damping rubber body having an inner bore through which the vibrating body is inserted. An upper side surface thereof comes into contact with the base while the remaining outer side surface thereof is retained by a bracket which is secured to the base. First and second insert members, each having a rigidity greater than that of rubber, are respectively embedded in the axially central portion of the rubber body, except for both axial end portions thereof, in symmetric relation with each other with respect to the inner bore of the rubber body. The first insert member has a flat upper surface and an arc-shaped lower surface. The flat upper surface of the first insert member is flush with the upper side surface of the rubber body while the arc-shaped lower surface thereof is close to the inner bore within a predetermined interval. The second insert member has a sheet-like configuration of an arc-shaped cross section. The lower surface of the second insert member is flush with the lower side surface of the rubber body while the upper surface thereof is close to the inner bore within a predetermined interval.
