Conventional worms have a uniform diameter, and the worm and the worm wheel mesh at one point. Therefore, it is not possible to cope with a case where a certain contact area is required between the worm and the worm wheel, such as a case where electrical connection is made via a worm gear. The present invention has been devised to secure a contact area between the worm and the worm wheel in such a case. The present invention will be described with reference to the drawings.
The diameter of the worm is continuously changed from the both ends of the worm to the center of the worm so that the diameter of the worm is adjusted to the outer circumference of the worm wheel (2). Change continuously towards the center of the worm wheel. This allows the worm to be in constant contact with multiple teeth of the worm wheel,
A contact area can be secured. In the drawings, the diameter of the center portion of the worm is reduced. However, when the worm wheel is provided at the end of the worm, the diameter of the worm end is the smallest.
