Document Type and Number:
Japanese Patent JP2016070322
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a speed changer having a structure capable of restricting a leakage of grease toward an input side member, restricting an increasing of manufacturing cost and restricting a reduction in productivity.SOLUTION: One preferred embodiment of a speed changer of this invention comprises a bracket to which an input side member is attached and a speed changing part. The speed changing part comprises a planetary rotating member constituting a planetary speed changing mechanism together with a sun rotating member, and a washer for supporting the planetary rotating member from one side. A bracket main body part of the bracket comprises the first partition wall for partitioning the input side member and a speed changing part, the second partitioning wall part protruded from the other surface of the first partitioning wall part and having an annular inner surface and a supporting part positioned inside in a radial direction of the second partitioning wall part to support the washer from one side. The first partitioning wall part and the supporting part are a part of a single member. An inside in a radial direction of the second partitioning wall part is provided with a clearance. The clearance is connected to a space where the sun rotating member and the planetary rotating member are arranged.SELECTED DRAWING: Figure 1
