- the diameter D3 of the distal end surface 24 is set to be smaller than the inner diameter D6 of the cylindrical member 14. Therefore, when the columnar member 12 is lowered, the tapered surface 41 of the columnar member 12 and the inner peripheral upper edge 36 of the cylindrical member 14 come into contact as shown in FIG.
- the bottom surface diameter D2 of the groove 17 is set to be larger than the inner diameter D6 of the cylindrical member 14.
- the inner peripheral surface 35 of the cylindrical member 14 has a groove 17 in the horizontal positional relationship. It is arranged on the inner side (axis side) from the bottom surface 23 of the.
- FIG. 25 illustrates a state where the columnar member 12 is further lowered. Since the height of the peak of the protrusion 16 of the columnar member 12 is lower below the upper side and the hardness of the columnar member 12 is higher than that of the cylindrical member 14, the protrusion 16 is formed on the cylindrical member 14. As it bites in, the cylindrical member 14 descends while plastically deforming much. At this time, the protrusion 16 is plastically deformed to a lesser extent than the cylindrical member 14. Since the columnar member 12 is provided with the height changing portion 20 and the tapered surface 41 whose side surface shape is inclined, the plastically deformed portion of the cylindrical member 14 does not flow so much downward, and the groove 17 It enters while flowing in (flows in). As the tubular member 14 flows somewhat downward, the cylindrical member 14 is formed with a convex plastic deformation portion 70 (in the drawings described below, this convex plastic deformation portion 70 is omitted). is doing).
- FIG. 26 illustrates a state where the columnar member 12 has reached the lowest position and stopped. Since the projection 16 of the columnar member 12 plastically deforms the cylindrical member 14, and the cylindrical member 14 is set in the mold jig 30 and cannot be deformed outward, the upper surface 33 of the cylindrical member 14 is more than before the deformation. High Arranged. Further, the inner peripheral surface 35 of the cylindrical member 14 is also arranged on the inner side than before the deformation. As shown in FIG. 27, the plastically deformed portion of the cylindrical member 14 sufficiently enters the groove 17 of the columnar member 12. Further, when the projection 16 of the tubular member 14 is bitten and the projection 16 of the columnar member 12 is plastically deformed, work hardening occurs in both deformed portions.
- the hardness of the plastic deformation part becomes high. Therefore, the columnar member 12 and the cylindrical member 14 are firmly fastened by the plastic deformation portion of the cylindrical member 14 sufficiently entering the groove 17 of the columnar member 12 and the work hardening accompanying the plastic deformation.
- one side surface 27 of the protrusion 16 coincides with the diameter direction, and the other side surface 28 of the protrusion 16 is inclined with respect to the one side surface 27. Therefore, the fastening strength around the axis of the columnar member 12 and the cylindrical member 14 varies depending on the direction of the torque. For example, in FIG. 27, when the cylindrical member 14 is fixed, a higher fastening strength can be obtained by applying a clockwise torque to the columnar member 12 than by applying a counterclockwise torque to the columnar member 12. Since the other side surface 28 of the protrusion 16 is inclined with respect to the diametrical direction, slippage tends to occur between the columnar member 12 and the cylindrical member 14 when a counterclockwise torque is applied to the columnar member 12. Because.
- the inner peripheral surface 35 of the cylindrical member 14 is the bottom surface 23 of the groove 17. It is arranged inside.
- the diameter D3 of the front end surface 24 of the columnar member 12 and the bottom surface diameter D2 of the bottom surface 23 are set so that such a relationship is ensured even if the inner diameter D6 of the cylindrical member 12 varies. Therefore, even when the inner diameter D6 of the cylindrical member 12 varies, the inner peripheral surface 35 of the cylindrical member 14 in the horizontal positional relationship when the columnar member 12 contacts the inner peripheral upper edge 36 of the cylindrical member 14. There is no gap between the groove 17 and the bottom surface 23 of the groove 17. If there is no gap between the inner peripheral surface 35 of the cylindrical member 14 and the bottom surface 23 of the groove 17, the columnar member 12 is further lowered to deform the cylindrical member 14. As a result, the plastically deformed portion sufficiently enters the groove 17.
- the upper end portion 22 of the height changing portion 20 of the protrusion 16 is rounded. Therefore, from the state where the columnar member 12 is lowered and the height changing portion 20 of the protrusion 16 is in contact with the cylindrical member 14, the constant height portion 19 of the protrusion 16 is also in contact with the cylindrical member 14.
- the force for lowering the columnar member 12 is suppressed from suddenly decreasing. Therefore, it becomes easy to control the descending speed of the columnar member 12. It is also possible to detect a change in force for lowering the columnar member 12 and to estimate the lowered position of the columnar member 12 based on the change force. In this way, it is possible to perform an accurate fastening compared to the press-fitting control based only on the movement distance of the columnar member 12.
- the phase shift between the pair of first contact surfaces 25 and the pair of second contact surfaces 26 is not limited to 90 degrees. Even if the phase shift is an angle other than 90 degrees, the contact surfaces 25 and 26 can accurately align the axis of the columnar member 12 and the axis of the cylindrical member 14. 5 or more surfaces such as the first contact surface 25 and the second contact surface 26 can be provided. By arranging multiple abutment surfaces and making the arrangement zero for the vector addition of the force acting on the abutment surface during press-fitting, the axis of the columnar member 12 and the axis of the cylindrical member 14 are accurately aligned. Can be made.
- a bottom groove 38 that makes a round in the circumferential direction can be formed near the outer periphery of the bottom 37 of the mold jig 30.

- This type of mold jig 30 can also be used in the first to fourth embodiments described above.
- the columnar member 12 and the cylindrical member 14 can be fastened without using the mold jig 30.
- the cylindrical member 14 is positioned on the support base 40. Even if the mold jig 30 is not used, the cylindrical member 14 is thicker (distance between the outer peripheral surface 31 and the inner peripheral surface 35) or the hardness of the cylindrical member 14 is higher than the hardness of the columnar member 12. In the case where the diameter of the cylindrical member 14 is significantly smaller, the plastic deformation portion of the cylindrical member 14 can sufficiently enter the groove 17 of the columnar member 12.

Nevertheless, as is clear from the graph in the lower half of Figure 32, work hardening has occurred and the hardness has increased.
- the cylindrical member 14 has entered the groove 17 deeply.
- the hardness is increasing in all of the rows to (f).
