Abstract:
The present invention is configured so that: a heat-resistant hard-material guide pin and an insulating synthetic-resin-material sliding member are integrated; an insert part and an extension part are provided to the sliding member; the thickness of the extension part is less than the thickness of the insert part; an air passage is formed in the extension part, thereby forming a thin-walled deforming part; and when the extension part is subjected to thermal expansion, the surface of the thin-walled deforming part is expanded toward the air passage.
