In order to prevent the seal member from coming off the groove in the above structure, a method is adopted in which the opening of the groove is deformed so as to be narrow or both are adhered with an adhesive. ing. However, if the deformation of the groove is small, the seal member is easily detached. In particular, it is difficult to return the seal member to the groove because the seal member is in a string shape, and if the deformation of the groove is large, the seal member is detached from the groove. Work becomes difficult and there is a risk that the seal member may be cut off at the edge of the groove. Further, even if an adhesive is used, the adhesive is used in sewage, so that the adhesive effect is not sufficiently exhibited, and the seal member is detached in a short time, so that it is difficult to hold the seal member in the groove.

Accordingly, the present invention provides a sewage lid for a garbage truck that facilitates the work of attaching and detaching the seal member and allows the seal member to be securely held in the groove.
