摘要
An oscillatory linear actuator includes an electromagnetic core block including an electromagnet (electromagnetic part), and a magnetic block that holds permanent magnets so that the permanent magnets face the electromagnet with a predetermined space in between. The electromagnetic core block integrally includes a core, a coil bobbin, and a base, the core and the coil bobbin forming the electromagnet, and the base holding the core and the coil bobbin. The magnetic block includes the permanent magnets and a frame that holds the permanent magnets so as to allow the permanent magnets to oscillate freely and holds the electromagnetic core block. The frame has a guide portion that guides the electromagnetic core block to adjust a positional relation of the permanent magnets and the electromagnet, and the base is fixed to the frame inside the guide portion.
