PROBLEM TO BE SOLVED: To provide a linear actuator which eliminates the risk of catching wiring connected to a plurality of coils on an inner circumferential surface of a main body part when inserting a yoke into the inner circumferential surface of the main body part.SOLUTION: A linear actuator 100 comprises: a first tube 10 with which a plurality of coils 41 held by a cylindrical yoke 40 are provided insides; a rod 30 which is freely movable in an axial direction within the yoke 40; and a plurality of permanent magnets 31 which are held side by side with the rod 30 in the axial direction and disposed oppositely to the plurality of coils 41. On an inner circumferential surface of the first tube 10, a groove 16 for accommodating wiring 44 connected to the plurality of coils 41 therein is provided in a direction of an axial line.SELECTED DRAWING: Figure 1 |
