PURPOSE:To reduce vibrations due to a hook type joint by means of an offset effect as well as to improve a feeling of driving comfortableness, by supporting an intermediate bearing for a propeller shaft on a frame cross member and a rear body in a parallel manner via a rubberlike elastic member. CONSTITUTION:An insulator 14 into which an intermediate bearing 13 supporting a propeller shaft 11 is inserted is formed into a first elastic member and a second elastic member. And, brackets 15a and 16a supporting the first elastic member are locked to a frame 12a, while brackets 15b and 16b supporting the second elastic member are locked to a rear body 19. Frames 12a and 12b are unitized in one by means of welding or the like, on which a cab is supported, and simultaneously supporting the rear body 19 via a rubber mount 20. In consequence, vibrations of the propeller shaft 11 are transmitted to be cab through two route by way of the first elastic member and the second elastic member, but phase comes reverse, so being negated with each other. Accordingly, vibrations in the cab are prevented from occurring.
