Abstract
提供一种能够防止壳体变形的减速机。环状的第一壳体（11）具有第一面（11a）、第二面（11b）、第一侧面（11c）以及第一开口（11d）。环状的第二壳体（12）具有第二开口，第二开口共有通过第一开口的中心的轴。环状的内齿齿轮（13）固定于第二壳体，具有内齿（13a）。柔性的筒状的外齿齿轮（14）配置于内齿齿轮的内侧，其轴向上的一端固定于第一壳体，且具有一部分与内齿齿轮啮合的外齿（14a）。椭圆形的波动发生器（19）配置于外齿齿轮的内侧，使外齿齿轮旋转。环状的加强部件（40）具有第三面（40a）、第四面（40b）、第二侧面（40c）以及第三开口（40d），并且使第三开口的中心与第一开口的中心一致而将第四面固定于第一壳体的第一面。加强部件（40）的面刚性比第一壳体（11）的面刚性高。
