摘要:
A rotary reciprocating drive actuator includes: a movable body including a shaft portion and a magnet fixed to the shaft portion; a fixing body including a core assembly, the core assembly including a core body and coils, the core body having magnetic poles, the core assembly being disposed such that the magnetic poles face an outer periphery of the magnet; and a pair of shaft supports configured to sandwich the core assembly in an extending direction of extension of the shaft portion and support the shaft portion at opposite sides of the core assembly such that the shaft portion is rotatable, in which a magnetic flux passing through the core body is generated by energization of the coils, causing reciprocating rotation of the movable body about an axis of the shaft portion by electromagnetic interaction between the magnetic flux and the magnet.
