Provided is a firm retainer that can be engaged with small pressing force, and that can maintain an engaged state without breaking after being secured even when force is exerted to pull out the retainer. The retainer comprises a male body (10) and a female body (20); the male body (10) is provided with an engaging protuberance (14) interposed by a male body shaft part (15) standing upright from a male body base part (13), a flange part (16) on the tip of the male body shaft part (15), and a narrow part (17) smaller in diameter than the flange part (16); the female body (20) is provided with a female body shaft part (24) standing upright from a female body base part (23), the female body shaft part (24) being larger in diameter than the flange part (16) of the male body (10); a shaft hole (25) that opens in an outside surface (22) and accommodates insertion of the engaging protuberance (14) is formed in the female body shaft part (24); a stepped surface (26) that is smaller in diameter than the flange part (16) and that engages with the narrow part (17), and a fitting space (27) into which the flange part (16) is fitted, are formed in the shaft hole (25); a dividing groove (28) is formed such that the portion extending from the female body base part (23) through the stepped surface (26) to part of the female body shaft part (24) is divided into at least two parts along the shaft hole (25); and the male body (10) and female body (20) are engaged using the elastic deformation of the divided stepped surface (26). |
