A speed reducer is provided with: a first bearing mounted to a support member; an output member supported by the first bearing and rotating about a first rotation axis; an internal gear connected to the output member and rotating with the output member about the first rotation axis; a second bearing mounted to the support member radially outside the first bearing; and a pinion gear which is supported by the second bearing, rotates about a second rotation axis different from the first rotation axis, and meshes with the internal gear. At least part of the second bearing is located closer to theinternal gear than a plane which passes through the far end of the first bearing relative to the internal gear in an axial direction parallel to the second rotation axis and which is perpendicular tothe second rotation axis.

    减速器具备:第1轴承,其安装于支承构件;输出构件,其支承于第1轴承,且以第1旋转轴为中心旋转;内齿齿轮,其与输出构件连结,且与输出构件一起以第1旋转轴为中心旋转;第2轴承,其在比第1轴承靠径向外侧的位置安装于支承构件;以及小齿轮,其支承于第2轴承,且以与第1旋转轴不同的第2旋转轴为中心旋转,并与内齿齿轮啮合。第2轴承的至少一部分位于比通过第1轴承的在与第2旋转轴平行的轴向上远离内齿齿轮的端部且相对于第2旋转轴正交的平面靠内齿齿轮侧的位置。
