PUMP DEVICE FOR VEHICLE AND BRACKET FOR VEHICLE

WIPO Patent Application WO/2016/104545

A1

The objective is to increase the rigidity of a bracket, thereby suppressing the transmission of vibration from a pump to a vehicle body. A ring-shaped part 12 of a bracket 11 is provided with a trapezoidal convex part 13 running from an inner peripheral edge 12C to an outer peripheral edge 12D of the ring-shaped part and having a top surface region 13A, an outer-wall-side descending region 13B, and an inner-wall-side descending region 13C. Furthermore, the ring-shaped part 12 and one vehicle body attachment part 17 are connected via a nonlinear connecting part 20, and the ring-shaped part 12 and another vehicle body attachment part 18 are connected via a nonlinear connecting part 21. Thus, the second moment of area of the ring-shaped part 12 can be made larger and the bending rigidity of the bracket 11 can be increased. Furthermore, it is possible to prevent the connecting part 20 between the ring-shaped part 12 and the vehicle body attachment part 17 and the connecting part 21 between the ring-shaped part 12 and the vehicle body attachment part 18 from serving as vibration nodes, thereby preventing vibration between the ring-shaped part 12 and the vehicle body attachment parts 17 and 18.
