A joining structure, a method of producing same and a wire exterior cover using the joining structure. The joining structure comprises a joining part formed by butt-welding a plate surface part of a first resin plate made of a first resin, and an end surface part of a second resin plate made of a second resin. In the joining structure, a foam resin is used for the first resin and a foam resin or a non-foam resin is used for the second resin. The joining part has a welding recess in a surface of the plate surface part. In an internal corner of a reverse surface, there is a padding section formed by melt-flowing and solidifying of at least the first resin out of the first resin and the second resin.

Joining structure, method of producing same, and wire exterior cover

Provided are a joining structure, a joining method, an exterior body for a wire harness, and a wire harness capable of firmly joining members having different physical properties while reducing the thickness of a joint part. The joining structurejoins a first membermade of a first resin and a second membermade of a second resin, wherein: the second resin has physical properties having a higher foaming ratio than the first resin; and a recessed joint partis provided which reaches at least the inside of the first memberfrom the outer surface side of the second member in a state in which the first memberand the second memberare superimposed. Furthermore, a method for manufacturing the joining structurecomprises the steps of: superimposing a first membermade of a first resin and a second membermade of a second resin having physical properties having a higher foaming ratio than the first resin; and joining the first memberand the second memberby forming the recessed joint partby pressing and hot-melting the second memberuntil the recessed joint partreaches at least the inside of the first memberfrom the outer surface side of the second member

Joining structure, joining method, exterior body for wire harness, and wire harness

An electric wire outer cover is provided which is to be fitted around an electric wire and which has a tubular housing portion where the electric wire is to be housed, the housing portion being formed of a sheet, the housing portion being formed in a folded state. Further, walls forming the housing portion include a first wall having a projection formed therefrom and a second wall having a hole formed therein, and the housing portion is formed by engagement between the first wall and the second wall through melting of the projection that has passed through the hole and welding of the melted projection to the second wall.

Electric wire outer cover and covered wire harness

A wire exterior body and an exterior-covered wire harness, capable of reducing vibration noise generated by vibration of the exterior body attached to a vehicle or the like and the wire harness in the exterior body, caused by vibration of the vehicle or the like, are provided. A wire exterior body to be attached to an outer periphery of a wire, formed by bending a resin sheet, includes a plurality of wall parts extending along the extending direction of the wire and forming an accommodating part for accommodating the wire. At least one of the plurality of wall parts has a protruding part protruding from the at least one wall part.
