Motor having speed reduction device

摘要

In a motor having a motor body (2) and a speed reduction devise (3) composed of gear housing (21), a worm wheel (24), worm shaft (28) with a worm (28a), and first and second bearings (22a&22b) rotatably supporting the worm shaft on opposite sides of the worm, the first bearing on a side of the motor body inclines a given angle to a bending side of the worm shaft, when the worm shaft is bent by an overload transmitted thereto via the worm wheel. Accordingly, a locally concentrated frictional wear of the bearing is reduced.
