PURPOSE:To contrive to facilitate the working of parts and to make the whole device small by a structure wherein an engaging body with a support is formed with a frame affixed on seats arranged on a supporting body and engaging bodies with a pivot are formed with projections provided at both ends of an elastic body. CONSTITUTION:The engaging body with the pivot 12 is formed with the projection 17 provided at an end of the elastic body 14 so as to contact the head of a pivot 3 with the elastic body 14. The pivot 12 having a spherical head is firmly fixed to the lower part of the support 3, onto which a bearing shoe is fitted. The frame 15, having two engaging holes with the two supports 3 therein, is affixed on the seats 10 arranged on the supporting body 8 by means of bolts 16. The elastic body 14 is positioned by the projections 17, with which the pivots 12 engage, provided at the both ends of the elastic body, because the supports 3, to which said pivots 12 are respectively fixed, are positioned by the engaging holes of the frame 15. Owing to the structure as mentioned above, the axially dimensional restriction can be relaxed. |
