Case and actuator device

摘要

A case is formed by Injection molding of composition of resin and includes an accommodation chamber which is formed therein for holding functional components. The composition of resin contains from 40 to 70 wt % of polybutylene terephthalate resin (PBT) and from 60 to 30 wt % of acrylonitrile-butadlene-styrene (ABS). The case satisfies a superior rigidity, impact load carrying capacity and chemical resistance.
