- the mounting legs are connected to each other in an annular shape by arc-shaped reinforcing ribs on the outer surface of the gear housing, and are connected to reinforcing ribs that extend radially from the support cylinder. Thereby, the rigidity of the gear housing is increased.
- the reinforcing rib has a structure in which the tip side is easily tilted simply by being erected in a plate shape from the outer surface of the gear housing. Therefore, in order to ensure the rigidity of the rib, for example, it is necessary to increase the thickness of the rib, which increases the material and weight of the gear housing.

That is, since the tip of the side wall 11f in the standing direction is connected by the upper wall 11i of the bulging portion 11e, the rigidity is increased. Therefore, the shape of the gear housing 11 is simpler than the conventional configuration in which a plurality of reinforcing ribs are provided.

Since the support cylinder part 11j is connected to the bulging part 11e, the bulge part 11e can increase the rigidity of the support cylinder part 11j.
- the support cylinder portion 11j includes an outer cylinder 11k extending outward from the upper wall 11i, and an inner cylinder 11l extending inward from the upper wall 11i and communicating with the outer cylinder 11k. That is, the upper wall 11i of the bulging portion 11e is connected at an intermediate position in the extending direction of the support cylinder portion 11j.

The output shaft 13 can be firmly supported.
- the support cylinder portion 11j needs to secure rigidity capable of receiving a force (reaction force from the load) in a direction orthogonal to the axis applied to the output shaft 13, and in particular, a base end of the support cylinder portion 11j. A large force is applied to the tip. And, in order to ensure rigidity in the support cylinder part that protrudes greatly outward from the upper wall 11i and supports it, for example, the number of ribs that reinforce the support cylinder part is increased or the wall thickness is increased to achieve high rigidity. Need to design.
- the outer cylinder 11k and the inner cylinder 11l both require a small amount of protrusion from the upper wall 11i.
- the rigidity of the support tube 11j can be ensured even if the support cylinder portion 11j is designed to have a relatively low rigidity without increasing the number of the members or increasing the thickness. Therefore, for example, even when the internal ribs 11m and 11n that reinforce the support cylinder portion 11j (inner cylinder 11l) are provided as in the present embodiment, the number of ribs is reduced or the wall thickness is reduced.
- the shaft 13 can be firmly supported. As a result, the material and weight of the gear housing 11 can be reduced, and consequently the cost manufacturing cost of the gear housing 11 can be reduced.
- the side wall 11f of the bulging part 11e and the inner cylinder 11l are connected by a plurality of internal ribs 11m and 11n in the internal space expanded by the bulging part 11e. Therefore, the rigidity of the inner cylinder 11l and the side wall 11f can be enhanced mutually. Further, when a rib is provided outside the housing to reinforce the support cylinder portion 11j, for example, water may be collected in a portion surrounded by the rib. However, in the internal ribs 11m and 11n, Avoided.

Can do. That is, the bearings 14a and 14b are provided only on both sides where a large force is applied to the support cylinder portion 11j, that is, excluding the intermediate portion. Therefore, compared with the case where a bearing is provided in the whole axial direction including the intermediate part of the support cylinder part 11j, for example, material cost can be reduced without providing a bearing wastefully.
- a space for storing lubricating oil can be provided between the intermediate portions, that is, between the bearings 14a and 14b, for example, scattering of the lubricating oil expanding at high temperatures. Can be reduced.

- the side wall 11f may be changed to any other shape as long as the attachment feet 11d can be connected to each other.
- the side wall 11f may be disposed so as to connect the attachment feet 11d in an annular shape. That is, the side wall 11f may be formed so as to bulge in a columnar shape toward the outside, that is, concentrically with the support cylinder portion 11j.
- the mounting foot portion 21 of this example is formed so that the triangle having the apex thereof deviates from the support tube portion 22 that supports the output shaft 13, that is, does not overlap when viewed from the tip of the mounting foot portion 21.
- the bulging portion 23 is formed so that the upper wall 23b has a substantially rhombus shape when viewed from the tip of the mounting foot portion 21 so that the side wall 23a connects the plurality of mounting foot portions 21 and the support tube portion 22. Yes. In this way, the material and weight of the gear housing 11 can be reduced while increasing the rigidity of the support tube portion 22 together with the mounting foot portion 21.

- the shape of the upper wall 26b becomes a substantially triangular shape.
- the support cylinder part 25 is formed so as to have an inner cylinder (not shown) in the internal space expanded by the bulging part 26. Even in this case, the material and weight of the gear housing 11 can be reduced while increasing the rigidity of the support cylinder portion 25 together with the mounting foot portion 24.

- the configuration of the internal ribs 11m and 11n may be arbitrarily changed. For example, the position corresponding to each attachment foot portion 11d, that is, the internal rib (vertex connection rib) 11m extending toward each vertex of the triangle may be omitted.
- Inner ribs (side connecting ribs) 11n extending toward the center positions between the mounting feet 11d, that is, the centers of the respective sides of the triangle may be omitted. Or an internal rib may be provided in the position different from the said internal rib 11m, 11n.
