<p>PROBLEM TO BE SOLVED: To prevent the transmission of the vibration due to the hydraulic pulse from an oil pump to a frame, and to prevent the fluctuation of a distance between a driving pulley unified with the oil pump and a driven pulley unified with the frame so as to prevent the lowering of the service life of a V-belt in the oil pump provided with the driving pulley on the driving shaft of the oil pump. SOLUTION: Bracket means 20, 29, 30, 38 arranged between the oil pump 10 and a frame means 39 are formed of at least two vibration control parts 30, which are respectively formed of an inner cylinder part 34, an outer cylinder part 36 for covering the inner cylinder part on the same shaft and a vibration control rubber 32 interposed between the inner and the outer cylinder parts; first bracket parts 29, 38 fixed to the frame means 39 and for holding one of the inner and the outer cylinder parts of the vibration control part so that axial direction of the cylinder part is arranged along the circumferential direction in parallel with the circumferential direction in relation to the driving shaft 13 for coil pump; and a second bracket part 28 holding the oil pump 10 and holding the other of the inner and the outer cylinder parts of the vibration control part.</p> |
