Vibration insulator and unbalance detection device including vibration insulator

Abstract

There is provided a vibration insulator mounted between a cartridge and a wheel-side housing, in which the cartridge includes a rotor having a wheel and a rotational shaft and a bearing housing accommodating a bearing rotatably supporting the rotor, and the wheel-side housing is to be pressed to the bearing housing in an axial direction. The vibration insulator includes an annular outer ring portion having a wheel-side contact surface configured to come into contact with the wheel-side housing, an annular inner ring portion disposed inside the outer ring portion with a clearance from the outer ring portion and having a bearing-side contact surface configured to come into contact with the bearing housing, and a flexible support portion interposed between the outer ring portion and the inner ring portion and connecting the outer ring portion and the inner ring portion, the flexible support portion being elastically deformable.
