FIG. 10A is a front view of the mount rubber 11. The mount rubber 11 is an elastic body having a substantially cylindrical shape, and has a groove 11a formed in a circumferential direction of the outer peripheral surface. The mount rubber 11 has a through hole 11b into which the bush 17 is inserted and into which the bolt 15 is inserted.

FIG. 10B is a perspective view showing a procedure for assembling the mount rubber 11 and the bush 17 to the mounting plate 2. As shown in FIG.
1 and a communication portion 22 are formed. The support hole 21 supports the vehicle hydraulic unit 1 in an elastically supported state through the groove 11 a of the mount rubber 11.
And a circular shape having a hole diameter substantially the same as the outer diameter of the groove portion 11a. The communication portion 22 communicates with the end of the attached plate 2 and has a width smaller than the diameter of the support hole 21.

In mounting the mount rubber 11 and the bush 17, first, the groove 11a of the mount rubber 11 is fitted into the support hole 21 via the communication portion 22, as indicated by the arrow S1. At that time, since the width of the communication portion 22 is smaller than the outer diameter of the groove portion 11a, the mount rubber 11 which is an elastic body is deformed so as to be crushed from the side surface, and is passed through the communication portion 22 and fitted into the support hole 21. Subsequently, as indicated by an arrow S2, the bush 17 is inserted into the through hole 11b of the mount rubber 11 fitted into the support hole 21.

FIG. 11 is a front view showing a state where the mount rubber 11 and the bush 17 are assembled to the mounting plate 2. The groove 11 a of the mount rubber 11 having an outer diameter substantially equal to the diameter of the support hole 21 is fitted into the support hole 21.
