Claims

[Claims for Utility Model Registration] (1) A coil holding member whose one end side is pivotably supported and a coil holding member which is attached by being wound in opposite directions along the swinging direction of the coil holding member. 1. A movable mechanism having a second coil, an outer yoke extending oppositely to sandwich the movable mechanism along the swinging direction of the movable mechanism, and each of the opposing outer yokes. It is characterized by comprising a fixing mechanism having permanent magnets arranged on the surface so that those facing each other have the same polarity and those adjacent to each other have opposite polarities. Oscillating type linear motor. (2) A hollow portion is formed in the coil holding member along a swinging direction of the coil holding member,
The first and second coils are positioned and attached to the coil holding member so as not to block the hollow portion, and the fixing mechanism further includes:
A utility model registration comprising a center yoke that penetrates the hollow part of the coil holding member, extends along the direction in which the outer yoke extends, and has both ends supported by the outer yoke. An oscillating linear motor according to claim 1. (3) The coil holding member and the fixing mechanism include:
The oscillating linear motor according to claim 1 or 2, wherein both of the motors are formed to have a substantially fan shape. (4) The outer yoke forming the fixing mechanism can be disassembled into a plurality of members with the permanent magnet attached, and the center yoke is
The oscillating linear motor according to any one of claims 1 to 3, which is configured to be assembled or disassembled together with a plurality of members forming the outer yoke. .
