    Abstract: An electromotive unit includes a linear motor, a motor case containing the linear motor, a movable element connected with the linear motor and reciprocatingly driven with respect to the motor case, and a sealing material sealing the gap between the movable element and the opening of the motor case. The sealing material includes a contact portion contacting the movable element; and a recessed portion formed around contact portion, having a ring-shaped groove facing the outside of the motor case, and elastically deformable according to reciprocating movement of the movable element. This aspect provides an electromotive unit that hardly generates noise while the movable element is being reciprocatingly driven; and a small-size electrical appliance including the electromotive unit.

    Abstract: 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.

    Abstract: An oscillatory linear actuator includes an electromagnet that changes a magnetic field periodically, a first movable body, a second movable body, a holder, and a coupling spring. The first movable body is disposed on one side in the first direction of the electromagnet, includes a permanent magnet, and acts on a target object. The permanent magnet reciprocates in a second direction intersecting with the first direction by the electromagnet. The second movable body is juxtaposed to the first movable body and reciprocates in the second direction. The holder holds the first and second movable bodies to provide space between the first and second movable bodies and the electromagnet and to allow the first and second movable bodies to move in the second direction. The coupling spring is disposed on one side in the first direction of the holder and couples the first movable body and the second movable body.
