Abstract

A joining device includes: a holding portion that holds a shaft portion of a metal member, and that pushes the metal member toward one side in an axial direction of the shaft portion; a supporting portion that supports a thermoplastic resin member; a heating portion that heats a surface at the one side in the axial direction of a distal end portion, which is provided at the one side in the axial direction of the shaft portion, to a melting temperature of the thermoplastic resin member; a sleeve portion that is provided at an outer peripheral side of the holding portion, that is disposed so as to overlap with the distal end portion; and an outer tube portion that is provided at an outer peripheral side of the sleeve portion, an end portion of the outer tube portion abutting a surface of the thermoplastic resin member.

First claim

What is claimed is:

1 . A joining device, comprising:
a holding portion that is configured to hold a shaft portion of a metal member, and that is configured to push the metal member toward one side in an axial direction of the shaft portion in a state in which the shaft portion is held by the holding portion; a supporting portion that is configured to support a thermoplastic resin member from a surface of the thermoplastic resin member at the one side in the axial direction; a heating portion that is configured to heat a surface at the one side in the axial direction of a distal end portion, which structures a portion of the metal member and is provided at the one side in the axial direction of the shaft portion, to a temperature at which a thermoplastic resin that structures the thermoplastic resin member, melts; a sleeve portion that is tubular, that is provided at an outer peripheral side of the holding portion, that is disposed so as to overlap with the distal end portion as seen from the axial direction, and that is configured to move in the axial direction relative to the holding portion; and an outer tube portion that is formed in a shape of a tube provided at an outer peripheral side of the sleeve portion and accommodating the metal member at an inner peripheral side thereof as seen from the axial direction, and that is configured to move in the axial direction relative to the sleeve portion, an end portion of the outer tube portion at the one side in the axial direction being configured to abut a surface of the thermoplastic resin member at another side in the axial direction.

2 . The joining device of claim 1 , further comprising a restricting portion that restricts relative rotation between the metal member and the holding portion around the axial direction,
wherein the heating portion is a driving portion that, in a state in which the surface at the one side in the axial direction of the distal end portion is made to abut the thermoplastic resin member, rotates or swings the holding portion around the axial direction and is configured to heat the surface by friction between the surface and the thermoplastic resin member.

3 . The joining device of claim 2 , wherein:
the metal member further has a held portion that is provided at the one side in the axial direction of the shaft portion and at the other side in the axial direction of the distal end portion, and that is configured to be held by the sleeve portion, a held-portion-side flat surface portion that runs along the axial direction is provided at the held portion, a sleeve-side flat surface portion, that is made to abut the held-portion-side flat surface portion and that can restrict relative rotation between the sleeve portion and the metal member around the axial direction, is provided at the sleeve portion, and the sleeve portion is configured to rotate around the axial direction.
