CASE AND ACTUATOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a case and an actuator device capable of making a rigidity, an impact resistance, and a chemical resistance compatible with each other. SOLUTION: This actuator device comprises the case 4 forming a storage chamber 4a and functional parts disposed in the storage chamber 4a of the case 4. The case 4 is formed by injection-molding a resin composition including polybutylene terephthalate resin(PBT) of 40 to 70% and acrylonitrile-butadiene- styrene resin(ABS) of 60 to 30% to make the rigidity, impact resistance, and chemical resistance of the case 4 compatible with each other.
