Claims

[Scope of utility model registration request]

(1) A rotary drive shaft, a linearly moving actuating rod that meshes with the rotary drive shaft through gears and racks, and an auxiliary actuating rod that is arranged parallel to the actuating rod and spaced apart from it by a certain distance; 1. A linear drive device comprising: a mechanism that connects the two operating rods together; and a bearing box that slidably supports the two operating rods.

(2) A gear provided on the drive shaft by making a part of the bearing that supports the drive shaft protrude in the axial direction within the bearing box, and fitting the protruding bearing part into a hole provided in the bearing box. 2. The linear drive device according to claim 1, wherein the actuating rod is meshed with rack teeth provided on the operating rod.
