Document Type and Number:
WIPO Patent Application WO/2017/094523
Kind Code:
A1
Abstract:
Provided is a resin bush capable of slidably supporting a shaft when the bush has been fitted in a housing; particularly, a resin bush suitable for use in an environment in which the effects of a difference in thermal expansion coefficients are likely to be prominent, such as a high-temperature environment, even when the housing and the shaft are made of a material such as a metal that has a different thermal expansion coefficient from that of the resin bush. In the resin bush (1), which is molded by extrusion molding, a slit (12) is formed from one axial end surface (11a) towards another end surface (11b). A recessed section (13) for a gate (a gate position), which is provided to the one axial end surface (11a), is provided in a position that is deviated from being symmetrical with the slit (12), at least with respect to a center axis O of a bush main body (10). The resin used for the material of the bush (1) is a resin having excellent heat resistance and chemical resistance, such as a PPS resin or a PEEK resin.
