PROBLEM TO BE SOLVED: To prevent surely a spindle from coming off in an engine mount and restrict relative displacement of an upper rigid member through which is inserted and supported the spindle.SOLUTION: A protruding part 54 as an engaging part is formed at a root part 52 of an engine-side spindle, and extension parts extending to an upper side of the root part 52 of the spindle are formed in a stopper member. In the extension parts are provided openings as engaged parts respectively. The protruding part 54 is engaged with the openings, so as to prevent the spindle from coming off and restrict relative displacement of an upper rigid member 2 through which is inserted and supported the spindle. This can strengthen rigidity of the root part 52 of the spindle and at the same time reduce the weight of a tip of a spindle-inserted part 51, thereby improving inertance.SELECTED DRAWING: Figure 4
【課題】エンジンマウントにおけるスピンドルの抜けを確実に防ぐとともに、スピンドルが挿通支持されている上側剛性部材の相対変位を規制する。【解決手段】エンジン側スピンドルの根元部52に係合部としての凸部54を、またストッパ部材にスピンドルの根元部52上方まで延びる延長部を形成して、その延長部に被係合部としての開口をそれぞれ設け、凸部54と開口とを係合させることでスピンドルの抜けを防止しつつ、スピンドルが挿通支持されている上側剛性部材2の相対変位を規制する。これにより、スピンドル根元部52の剛性が強化されると同時に、スピンドル挿通部51の先端の重量が軽くなりイナータンスが改善される。【選択図】図4
