ABSTRACT:
A bearing support device includes a rotor, a bearing member, and a bearing holding member. The rotor rotates about a rotation center axis. The bearing member rotatably supports the rotor within a bearing hole passing through the bearing member. The bearing holding member holds the bearing member in a secure manner within a fitting hole that passes through the bearing holding member along the center axis of the rotor via an engagement force produced by tightly fitting the bearing member. The rotor and bearing member are made of a resin. An engagement section is provided for tightly fitting the bearing member into the fitting hole relative to the bearing hole to enable an engagement force produced by the tight fitting to act in a direction that does not affect an inner diameter dimension of the bearing hole.
