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.
