Abstract
A vibration isolation holding device includes a body portion and an abutment member. The abutment member is arranged between the body portion and a bearing housing, and has an abutment surface abutting on the bearing housing, when a cartridge is held. A biasing member is disposed between the abutment member and the body portion. An interval between the body portion and the abutment member is regulated by a first regulating portion to be shorter than a natural length of the biasing member.
Claims10
A vibration isolation holding device configured for holding a cartridge, which includes a rotor having a wheel and a rotational shaft, a bearing configured for supporting the rotor rotatably, and a bearing housing configured for housing the bearing, while isolating a vibration, the device comprising:
- a body portion;
- an abutment member arranged between the body portion and the bearing housing, and having an abutment surface abutting on the bearing housing, when the cartridge is held;
- at least one biasing member disposed between the body portion and the abutment member along an axial direction of the rotational shaft;
- and
- a first regulating portion configured for regulating a position of the abutment member with respect to the body portion, so as to make an interval between the body portion and the abutment member shorter than a natural length of at least one the biasing member, and
- wherein the first regulating portion is fixed to the body portion, and is configured to be able to contact the abutment surface from an opposite side to the body portion as viewed from the abutment member.
