Claims

[Claims for Utility Model Registration] (1) In a reduction gear body that includes a gear train and a main plate that pivotally supports the gear train inside an outer housing, the housing has a plurality of seats on its inner peripheral surface. is integrally formed, and a groove is formed at a position equal to or slightly apart from the end face of the base plate, and a tomewa is fitted into the groove with the base plate in contact with the seat. A speed reducer characterized in that the base plate is fixed. (2) A small hole is formed in the end face of the seat on the inner peripheral surface of the casing, and a half-cut dowel that fits into the small hole is formed in the part of the base plate to be abutted opposite to the small hole in the seat, so that both The speed reducer according to claim 1 of the utility model registration claim, characterized in that the speed reducer is configured such that it is fitted and fixed. (3) A small protrusion is formed on the end face of the seat on the inner peripheral surface of the casing, and a small hole that fits into the small protrusion is formed in a portion of the base plate to be abutted opposite to the small protrusion of the seat, so that the two are connected. The speed reducer according to claim 1, which is characterized in that it is configured to be fitted and fixed.
