Abstract
A female snap button detachably receives a projection of a male snap button in a projection-receiving space. The female snap button includes an annular protrusion rising from a base and defining the projection-receiving space. In the annular protrusion, there are formed thick-walled portions with the thickness from the inner surface of the protrusion to the radially outer side being relatively thick and thin-walled portions with the thickness being thinner than that in the thick-walled portions. The thick-walled portions and the thin-walled portions are arranged alternately in the circumferential direction.

A female snap button made of synthetic resin which detachably receives a projection of a male snap button in a projection-receiving space, comprising:
- a disk-like base, and
- an annular protrusion rising from the base and defining the projection-receiving space above the base,
- wherein the annular protrusion includes thick-walled portions with the thickness from an inner surface of the protrusion to a radially outer side being relatively thick and thin-walled portions with the thickness being thinner than that in the thick-walled portions, the thick-walled portions and the thin-walled portions being arranged alternately in a circumferential direction,
- wherein the thin-walled portions are depressed radially inward between two circumferentially adjacent thick-walled portions.
