A worm gear reduction mechanism characterized in that an intermediate shaft is provided, and spiral teeth formed on a worm of the intermediate shaft are set in the same winding direction as spiral teeth formed on a worm on the drive side.

Claims

[Scope of utility model registration request]

In a worm gear reduction mechanism that performs deceleration via two or more sets of worm gears, an intermediate shaft that integrally includes a worm wheel that meshes with a worm on the driving side and a worm that meshes with a worm wheel on the driven side is interposed. A worm gear reduction mechanism, characterized in that the helical teeth formed on the worm of the intermediate shaft are set in the same winding direction as the helical teeth formed on the driven side worm.
