Side plate portions 28 from both sides of the lower surface of the upper end flat plate portion 26
are made to protrude, and bolt holes 29 for connection with the mount rubber 17 are bored at the lower end portions on both sides of these side plate portions 28.

By making the top bracket 12 and the mount frame 13 have the above-described structure, the arm 1
While the top bracket 12 is fixed at the first position, the second
As shown in Figures A to C, the mount frame 13
can be connected and fixed in any direction and position.

That is, A indicates the normal connection position, where the lower end flat plate part 21 of the top bracket 12 and the upper end flat plate part 26 of the mount frame are aligned and overlapped, and all bolt holes 25a to 25h are connected to bolt holes 27a to 27a.
