Abstract

A reliable and superior joining strength in entire joining parts of resin molded bodies including tilting portions is obtained by devising a shape and a size of each protrusion for welding provided in the joining parts of the resin molded bodies. In a structure of joining resin molded bodies according to the present invention, upper and lower half bodies 10 and 20 are joined with each other by means of a vibration welding method while the upper and lower half bodies 10 and 20 are being pressurized in a state in which joining parts thereof are butted into each other in a substantially entire area of the joining parts. The joining parts of the respective half bodies have vertical portions 11 and 13 and vertical portions 21 and 23 respectively vertical to a pressurizing direction and tilting portions 12 and 22 tilting relative to the pressurizing direction, and protrusions for welding 11E to 13E or 21E to 23E are provided in at least the joining part of one of the half bodies. Further, referring to a butting area of the protrusions in a butted state, the butting area in the vertical portions is set to be narrower than the butting area in the tilting portions.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a joining structure of resin molded bodies by means of a vibration welding method while applying a pressure to the pair of resin molded bodies in a state in which joining parts of the pair of resin molded bodies are butted into each other across a substantially entire area of the joining parts.

[0003] 2. Description of the Related Art

[0004] Conventionally, as a generally known method of joining a pair of resin molded bodies is available a so-called vibration welding method, in which a vibration is applied to the resin molded bodies in a state in which joining parts of the pair of resin molded bodies are butted into each other and pressurized so that the pair of resin molded bodies are joined with each other.

[0005] However, it is a publicly known problem in joining the resin molded bodies with each other by means of the vibration welding method that it is quite difficult to obtain a...
