Shown in). In this state, the engaged portion 24 of the operating member 20 is sandwiched in the vertical direction by the upper portion of the container body 101 and the fitting portion 13 of the cover member 10, so that the operating member 20 is stable. Further, since the stopper portion 21a is in contact with the lower end surface of the projecting plate portion 14, the operating member 20 does not wobble.

Further, since the engaged portion 24 of the operating member 20 is sandwiched in the vertical direction by the upper portion of the container body 101 and the fitting portion 13 of the cover member 10, the engaged portion 24 of the operating member 20 and the engaged portion 24 The engagement of the cover member 10 with the engaging convex portion 12 does not have to be so strong, and for example, the engaging force is sufficient to temporarily fix the cover member 10. As a result, the force that must be applied when engaging the engaged portion 24 and the engaging convex portion 12 can be reduced, so that the assembly work of the cap 1 becomes easy. Further, since the engaging force can be small, the engaging convex portion 12 can be made small.
