PROBLEM TO BE SOLVED: To solve the problem that a pin having been press-fitted into a disc-shaped member is inclined with respect to an axial line of the disc-shaped member.SOLUTION: A speed reducer comprises: a speed reduction mechanism configured to convert rotation force transmitted from an input part at a predetermined speed reduction ratio; a plurality of pins to which the rotation force converted by the speed reduction mechanism is transmitted; and a base part where each pin is press-fitted into a plurality of open holes. The base part has an inside region part that is a disc-shaped member and positioned close to a center of the base part in the periphery of the open hole, and an outside region part positioned at an opposite side to the inside region part with the open hole interposed therebetween. The base part is configured such that a difference between a load applied to the pin from the inside region part and a load applied to the pin from the outside region part is not more than a predetermined value.SELECTED DRAWING: Figure 4 【課題】円板状部材に圧入されたピンが円板状部材の軸線に対して傾斜してしまう。【解決手段】減速機を、入力部から伝達された回転動力を所定の減速比で変換する減速機構と、減速機構によって変換された回転動力が伝達される複数のピンと、複数の貫通穴に各ピンが圧入された基部とを備える構成とする。基部は、円板状部材であり、貫通穴の周囲において基部の中心寄りに位置する内側領域部と、貫通穴を挟んで内側領域部の反対側に位置する外側領域部とを有する。基部は、内側領域部からピンに掛かる荷重と、外側領域部からピンに掛かる荷重との差が所定値以下となる構成を持つ。【選択図】図４
