Claims

[Claims for Utility Model Registration] 1. In a bearing holding part of an electric motor, a ring such as an elastic body having a bearing holding part integral with a bracket and having a plurality of discontinuous parts in the circumferential direction η and a plurality of protrusions on the inside thereof. An electric motor characterized in that a bearing is held by. 2. In the scope of claims for utility model registration, paragraph 1, the dimensions of a bearing holding part that is integrated with a bracket and has multiple discontinuities in the circumferential direction, and the inner diameter dimension of a ring such as an elastic body that has multiple protrusions on the inside. is an electric motor characterized by the following settings. DR<DB≦D, where DR is the inner diameter of the inner protrusion of the rubber ring such as an elastic body DB: Bearing outer diameter DE: Bracket bearing holding part inner diameter.
