An instrument panel () includes a base material portion () made of a base material Mand a different material portion () made of a different material Mhaving a different thermal shrinkage from that of the base material Mand in the instrument panel (), the base material portion () and the different material portion () are connected in a state such that at least a part of the two materials do not overlap.

Resin component, and molding method and molding device for same

Provided are: an instrument panel capable of stably deploying a deployment part; and a method for manufacturing the instrument panel. An instrument panel is provided with: a base part; and a deployment part which is surrounded by the base part, faces an air bag, and includes a tear line, wherein a slit structure including a plurality of slits arranged so as to surround the tear line is formed in the deployment part.

Instrument panel and method for manufacturing instrument panel

An instrument panel () is formed by bonding a base material portion () composed of a base material Mand a different material portion () composed of a different material M. The different material portion () is infiltrated into the base material portion () and the infiltration portion () has a plurality of intermittent recessed portions.

This vibration welding device is a device that vibration welds an airbag holding box and an installment panel having a tear line. The vibration welding device is provided with a support jig that carries and affixes the installment panel during vibration welding. The support jig is provided with a groove that permits thermal expansion during vibration welding of the installment panel at a position differing from the tear line.
