Abstract
Official abstract text for this publication.
A speed reduction mechanism includes a bearing mechanism arranged on an axis of an output mechanism and including ball bearings that are arranged in parallel with each other in an axial direction of a differential case. The differential case is rotatably supported by the ball bearings of the bearing mechanism such that the entirety of an outer periphery of one of the ball bearings faces an inner periphery of a first housing element that accommodates the differential case and that is made of a material having a stiffness lower than a stiffness of a material of a rotation force applying member, and the entirety of an outer periphery of the other one of the ball bearings faces an inner periphery of the rotation force applying member.
First claim
Opening claim text (preview).
What is claimed is: 1. A speed reduction mechanism, comprising: a rotary shaft with an eccentric portion; an input member that is an external gear rotatably arranged on an outer periphery of the eccentric portion of the rotary shaft and having a plurality of through-holes arranged around an axis of the input member at equal angular intervals; a rotation force applying member that is an internal gear meshed with the input member and having teeth of which the number is larger t…
