PROBLEM TO BE SOLVED: To protect the plating of a bolt.SOLUTION: A transmission mount 1 comprises: a long-length upper plate-shaped metal fixture; a trapezoidal metal fixture 4 having a pair of inclined parts 40 which are oppositely arranged at both end parts of the metal fixture in a longitudinal direction, and extend so as to be inclined to the upper plate-shaped metal fixture side as progressing toward the outside from the inside of the longitudinal direction; a lower plate-shaped metal fixture 3 having a pair of horizontal parts 31 which are oppositely arranged at a side opposite to the upper plate-shaped metal fixture of each inclined part 40 of the trapezoidal metal fixture 4; and a pair of rubber elastic bodies 5 which are arranged between the inclined parts 40 of the trapezoidal metal fixture 4 corresponding to end parts of the upper plate-shaped metal fixture in the longitudinal direction, and connect them. The trapezoidal metal fixture 4 and the lower plate-shaped metal fixture 3 are fixed to each other by welding. A bolt hole into which a plated bolt 6 is inserted is formed at each horizontal part 31. A guide part 42 composed of a penetration hole which can guide the bolt 6 into the bolt hole of the lower plate-shaped metal fixture 3 by making the bolt penetrate the hole is formed at each inclined part 40.SELECTED DRAWING: Figure 3

    【課題】ボルトのめっきを保護する。【解決手段】トランスミッションマウント1は、長尺状の上側板状金具と、この金具の長手方向両端部にそれぞれ対向配置されかつ長手方向内側から外側に向かうに従って上側板状金具側に傾斜するように延びる一対の傾斜部40を有する台状金具4と、台状金具4の各傾斜部40の上側板状金具とは反対側に対向配置された一対の水平部31を有する下側板状金具3と、上側板状金具の長手方向各端部と対応する台状金具4の傾斜部40との間に配設され、両者を互いに連結する一対のゴム弾性体5とを備える。台状金具4と下側板状金具3とは、互いに溶接固定される。各水平部31には、めっきをかけたボルト6が挿通されるボルト孔が形成される。各傾斜部40には、ボルト6を貫通させて下側板状金具3のボルト孔に案内可能な貫通孔からなる案内部42が形成される。【選択図】図3
