Claims

[Scope of Claim for Utility Model Registration] (1) A main body casing of a reducer having an opening at one end and a locking protrusion on the inner circumference of the opening, and an opening in the main body casing. In order to cover the main body, a lid body is fitted into the opening and the back side abuts the protrusion of the main body casing, and a surface of the lid body such that a part of the hole faces the outer peripheral surface of the lid body. a circular arc hole formed on the side, one fitting groove formed on the peripheral wall of the circular arc hole, and another fitting groove formed on the inner peripheral side of the opening of the main body casing corresponding to the one fitting groove. A lid fixing device for a reducer, comprising a fitting groove, and a retaining ring that is removably fitted into the other fitting groove and one fitting groove to prevent the cover from coming off. (2) Utility model registration claim (1), wherein a regulating member is attached to the bottom of the arcuate hole of the lid body, and is located radially inside the retaining ring and restricts the diameter of the retaining ring from contracting. Lid body fixing device for the described reducer.
