Abstract
A securing structure for a stator includes the stator having a stator core, and a housing having an opening portion containing the stator core, and the housing includes a portion A where the clearance between the inner circumferential surface of the opening portion and the stator core is relatively smaller and the inner diameter of the opening portion is constant, and a portion B located adjacent to the portion A in the axial direction of the stator core where the clearance between the inner circumferential surface of the opening portion and the stator core is relatively larger.

A securing structure for a stator, comprising:
- the stator including a stator core;
- and
- a housing having an opening portion containing said stator core,
- said housing including a first portion opposite to one end in an axial direction of said stator core, where an inner diameter of said opening portion is constant, and a second portion opposite to the other end in the axial direction of said stator core and formed apart from said stator core while being directly opposite to said stator core, and
- a clearance between an inner circumferential surface of said opening portion and said stator core in said second portion being set larger than a clearance between the inner circumferential surface of said opening portion and said stator core in said first portion.
A securing structure for a stator, comprising:
- the stator including a stator core;
- and
- a housing having an opening portion containing said stator core,
- said housing including a first portion opposite to one end in an axial direction of said stator core, where an inner diameter of said opening portion is constant, and a second portion opposite to the other end in the axial direction of said stator core and formed apart from said stator core such that transmission of vibration from said stator core is suppressed, and
- a clearance between an inner circumferential surface of said opening portion and said stator core in said second portion being set larger than a clearance between the inner circumferential surface of said opening portion and said stator core in said first portion.
