A fastening structure includes: plural overlapping co-fastened members, a clearance hole being formed at at least one mating face of mutual mating faces of the plural co-fastened members, and a screw utilizing frictional heat to bore a hole and form a thread, passing through the clearance hole, and fastening the plural co-fastened members together.

Fastening structure and fastened structural body

There is provided a reinforcement for a vehicle having a main body portion that is formed in a hollow beam shape, and extends in a vehicle width direction while having both end portions thereof in the vehicle width direction supported by structural components of a vehicle, and whose cross-sectional surface area in a vehicle front-rear direction becomes progressively larger from the end portions in the vehicle width direction towards a central portion thereof.

A joining method is a method of joining a plate set composed by a plurality of stacked plate members including a first plate member and a second plate member by using a tapping screw. When the tapping screw is advanced into the plate set while the tapping screw is rotated in a state of applying a pressure onto the plate set so as to form through-holes in the first plate member and the second plate member, a first pressure applied onto the tapping screw is reduced down to a second pressure at the time when the tapping screw penetrates the first plate member.

Joining method and joining apparatus

A joint structure includes: a first steel plate; a second steel plate disposed along the first steel plate; a laser welding part that joins together a joint face part, which configures a first part of the first steel plate, and the second steel plate from one side in a plate thickness direction of the first steel plate and the second steel plate; and a fastening member that is screwed into, and fastens together, the second steel plate and a general face part from the one side in the plate thickness direction, the general face part configuring a second part of the first steel plate, being provided adjacent to the joint face part, and being disposed so as to be spaced apart from the second steel plate at the one side in the plate thickness direction.

Joint structure

A method of producing thermoplastic resin composite material in which a main base material containing thermoplastic resin and a sheet-like shaped auxiliary base material are integrally molded and are made into composite material. The production method includes the steps of: heating the auxiliary base material (step S); disposing the heated auxiliary base material in a mold (step S); disposing the main base material in the mold via the auxiliary base material (step S); closing the mold, and pressing together and integrally molding the auxiliary base material and the main base material (step S); and taking out the integrally-molded thermoplastic resin composite material from the mold.

Production method for the thermoplastic resin composite material

A coupling member head includes a holder configured to hold a coupling member at an end portion on a coupling target member side in an axial direction and configured to approach or separate from a coupling target member, a pair of electrodes, tips of the electrodes being positioned closer to the coupling target member side than a coupling member holding region of the holder, and a retraction mechanism configured to move the electrode to a radial outside of the holder when the holder approaches the coupling target member.

Coupling member head

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.

Joining method for joining a plate set

In a joining method for joining a first plate material and a second plate material by screwing a self-tapping screw from one direction in a state where the first plate material and the second plate material are put on top of each other, a recessed portion is formed in at least one of the first plate material and the second plate material, and in a state where the first plate material and the second plate material are put on top of each other such that the recessed portion is opened in a contacting face between the first plate material and the second plate material, the self-tapping screw is screwed from the one direction. When the self-tapping screw penetrates through the first plate material due to the screwing of the self-tapping screw, an excess part generated from the first plate material flows into the recessed portion.
