1. A fixing mechanism comprising:
a tubular housing; and
an attachment body that is fitted to an inner circumferential surface of the housing,
wherein in the fixing mechanism, a swage portion is formed in the housing, and the housing and the attachment body are fixed to each other,
wherein the attachment body has
one swage groove which is formed throughout a whole circumference of an outer circumferential surface, and
at least one inclined portion which is formed in a part at a side edge of the swage groove and is inclined outward in an axial direction of the housing from the side edge of the swage groove,
wherein in the housing, the swage portion is formed at a place corresponding to the swage groove, where at least the inclined portion is formed, and
wherein at least the inclined portion is configured to serve as a deformation allowing portion having a mechanical strength weaker than mechanical strengths at places other than the inclined portion of the attachment body,
wherein the attachment body has a small width groove which is formed adjacent to the swage groove in the axial direction of the housing and is smaller than a width of the swage groove in the axial direction of the housing,
wherein the small width groove is formed throughout a whole circumference of the attachment body,
wherein a part between the swage groove and the small width groove is configured to serve as the deformation allowing portion,
wherein the swage portion opposes the swage groove in a radial direction of the housing through a gap, and
wherein an outer edge of the inclined portion is in contact with the attachment body in the axial direction with a gap between the inclined portion and the attachment body.
