Rubber mount

摘要

A rubber mount includes a cylindrical rubber member (6) formed with an annular groove (12) to engage a component part (4) to be supported, and a threaded bolt (7) passed through a central axial bore (11) of the rubber member and having a threaded part (24) in a forward end thereof to be threaded into a base member (1). The intermediate part is provided with a larger diameter than the threaded part, and a pair of annular grooves (25, 26) are formed on an outer circumferential surface of the intermediate part. The rubber member is axially compressed by the head (21, 22) of the threaded bolt when the threaded bolt is fully threaded into the hole. The rubber mount consists a small number of component parts, and is easy to install, but is still able to firmly support the component part and provide a favorable vibration insulation capability.

1. A rubber mount for resiliently supporting a component part on a base member, comprising:
a cylindrical rubber member formed with a support groove on an outer circumferential surface thereof for engaging the component part and a central axial bore; and a threaded bolt passed into the central axial bore of the rubber member and including an intermediate part received in the central axial bore of the rubber member, a head provided on one end of the intermediate part and a threaded part provided on the opposite end of the intermediate part and threaded into a hole of the base member, the intermediate part being provided with a larger diameter than the threaded part; wherein a recess is formed on an outer circumferential surface of the intermediate part, the recess providing an area where no contact between the intermediate part of the threaded bolt and a surrounding wall surface of the central axial bore takes place in an unstressed state of the rubber member, the recess is arranged apart from the head and the threaded part, and the threaded bolt is dimensioned such that the rubber member is axially compressed by the head and thereby partly forced into the recess when the threaded bolt is fully threaded into the hole.
