接合构造体及其接合方法

Joint structure, and joint method thereof

Abstract

本发明提供适合将构成接合构造体的部件之间接合起来的接合构造体及其接合方法。为此,接合构造体(1)具有轴部件(10)、和内周面嵌合于该轴部件(10)的外周面的圆筒部件(20)。圆筒部件(20)具有:第1铆接部(21),其沿着在轴部件(10)的轴向设置的轴向槽(11)进行铆接;以及第2铆接部(22),其与轴向槽(11)卡合,该第2铆接部(22)以轴向的中间部在径向上缩径的方式,沿着在轴部件(10)的周面上设置的周向槽(12)进行铆接。
The purpose of the present invention is to provide: a joint structure with which members configuring the joint structure can be suitably joined; and a joining method therefor. Accordingly, a joint structure (1) is provided with: a shaft member (10); and a cylindrical member (20) which has an inner peripheral surface thereof fitted to an outer peripheral surface of the shaft member (10). The cylindrical member (20) is provided with: a first press-joined portion (21) which is press-joined along axial-direction grooves (11) provided to the shaft member (10) in an axial direction; and a second press-joined portion (22) which engages with the axial-direction grooves (11), and which is press-joined along a peripheral-direction groove (12) provided to a peripheral surface of the shaft member (10) by radially reducing the diameter of an intermediate portion in the axial direction.
