Claims

[Scope of utility model registration request]

(1) A structure in which a bearing that holds the output shaft of the motor in a fixed position is attached to the casing. The outer circumferential surface is locked to the circumferential edge of an opening formed at one end of the casing, and a bearing is disposed between the outer circumferential surface of the bearing at the other axial end of the shaft hole and the inner circumferential surface of the one end of the casing. A spacer holding an oil spacer is interposed between the outer peripheral surface of the bearing at the axial center of the shaft hole and the inner peripheral surface of one end of the casing. The motor bearing mounting structure consists of:

(2) Utility Model Registration Scope of the Claim In the motor bearing mounting structure described in claim 1, the spacer has an annular shape surrounding the bearing, and a groove is formed on the inner circumferential surface of the spacer around the entire circumference. and the above-mentioned oil spacer is placed in the groove.

(3) Utility Model Registration Scope of Claim 1 In the motor bearing mounting structure according to claim 1, the spacer is formed by a plurality of protrusions integrally protruding from the outer peripheral surface of the bearing along the circumferential direction of the shaft hole, An oil spacer is housed between adjacent protrusions in the circumferential direction of the shaft hole.

(4) Utility Model Registration Claim In the motor bearing mounting structure described in claim 1, the spacers are integrally provided along the circumferential direction of the shaft hole and protrude from substantially the entire circumference of the outer circumferential surface of the bearing. It is formed by a protrusion, and annular oil spacers are arranged on both sides of the protrusion in the axial direction of the shaft hole.
