Abstract
A fitting structure of an automatic transmission is comprised of a fitting member which is cylindrical, and a receiving member which is comprised of an opening portion to be fit with the fitting member. A diameter of a lead end of the fitting member is larger than a diameter of a rear end thereof, and a difference between the diameters of the lead end and the rear end are within elastic deformation range of the receiving member. A tightening force is created after fitting for holding the fitting member securely. An entire circumference of an edge portion of the lead end of the fitting member is formed with a predetermined curvature.

A fitting structure of an automatic transmission, the fitting structure comprising:
- a fitting member which is cylindrical, a diameter of a lead end thereof being larger than a diameter of a rear end thereof;
- and
- a receiving member comprising an opening portion to be fit with the fitting member, the receiving member being formed from a material of less rigidity than the fitting member.
A fitting structure of an automatic transmission, the fitting structure comprising:
- a fitting member comprising a fitting portion which is cylindrical, the fitting portion being formed in a tapering shape;
- and
- a receiving member comprising an opening portion to be fit with the fitting portion, the receiving member being formed from a material of less rigidity than the fitting member.
An assembly of an automatic transmission, the assembly comprising:
- a fitting member comprising a fitting portion which is cylindrical;
- and
- a receiving member comprising an opening portion into which the fitting portion is fit, being formed from a material of greater elastic deformation than the fitting member,
- wherein a diameter of a lead end of the fitting portion being greater than a diameter of a rear end of the fitting portion, a difference between the diameters being within an elastic deformation range of the receiving member, a diameter of the opening portion of the receiving member being smaller than a diameter of the fitting portion, a tightening force being created in the receiving member by elastic deformation thereof after fitting of the fitting member into the receiving member for holding the fitting member, and an edge portion of the lead end of the fitting portion being formed with a predetermined curvature.
