Claims

[Claims for Utility Model Registration] (1) A case for a reducer in which an output shaft boss and two or more intermediate shaft bosses are formed on at least one side of the case, wherein the center of the output shaft boss and A case for a reduction gear, wherein the distances from the center of each of the intermediate shaft bosses are the same. (2) an output shaft and at least one shaft meshing with the output shaft;
the case has two intermediate shafts, an output shaft boss for mounting the output shaft, and an intermediate shaft boss for mounting the intermediate shaft, the output shaft boss and the intermediate shaft boss for mounting the intermediate shaft. have the same diameter on the left and right sides, so that the output shaft and each of the intermediate shafts can be installed inverted within the case, and an input shaft boss provided on the left and right center line of the case. A speed reducer, wherein torque is transmitted from an input shaft to the intermediate shaft through a bevel gear provided on the intermediate shaft. (3) The speed reducer according to claim 2, wherein there are two or more intermediate shaft bosses, and the distance between the center of the output shaft boss and the center of each intermediate shaft boss is the same.
