Claims

[Scope of utility model registration request]

a carrier that is rotatably attached to the main body and rotates forward and backward at a certain angle; a sun gear fixed to the main body concentrically with the rotation center of the carrier;
A planetary gear that meshes with the sun gear and is rotatably attached to the carrier, a slide pin that is attached eccentrically to the rotational axis of the planetary gear, and a groove in which the slide pin engages with a radius of a swinging arm that extends in the direction and is rotatably attached to the main body concentrically with the center of rotation of the carrier, and a first output arm that is provided integrally with the swinging arm and has a slide pin formed at its tip. and a second output arm, the base end of which is rotatably connected to the main body, a slide pin formed at the distal end, and a groove in the radial direction in which the slide pin of the output arm slidably engages. and a slider that is supported for reciprocating linear movement and has a groove in which a slide pin of the second output arm slidably engages in a direction perpendicular to the direction of movement of the slider. A linear drive device characterized in that the first output arm and the second output arm intersect perpendicularly at a conveyance end.
