A gearbox includes a first split body and a second split body, and shaft protrusions are formed on split surfaces of the first split body and the second split body and through holes are formed in the split surfaces. A second recess on the second divided body side includes a second arc-shaped portion formed concentrically with an axial center of the worm wheel, and an upper linear portion and a lower linear portion linearly extending from both ends of the second arc-shaped portion toward the first divided body side. A first recess on the first split body side includes a first linear portion extending linearly in a direction orthogonal to the intersecting direction, and an upper arc-shaped portion and a lower arc-shaped portion formed so as to be continuous with both ends of the first linear portion.
一种齿轮箱包括第一分割主体和第二分割主体,并且轴突起形成在第一分割主体和第二分割主体的分割表面上并且通孔形成在分割表面中。位于第二分割主体侧上的第二凹部包括与蜗轮的轴中心同心地形成的第二弧形部分以及从第二弧形部分的两端朝向第一分割主体侧直线地延伸的上直线部分和下直线部分。位于第一分割主体侧上的第一凹部包括在与交叉方向正交的方向上直线地延伸的第一直线部分以及被形成为与第一直线部分的两端连续的上弧形部分和下弧形部分。
