<P>PROBLEM TO BE SOLVED: To reconcile easily putting-in and hardly coming-out by a simple structure. <P>SOLUTION: By pressing a male body 2 and a female body 1 under the condition that either one between the female body 1 and the male body 2 having a slotted part 3 formed therein is made of a material harder than that of the other one and, in addition, a tongued and grooved part 4 extending to the direction intersecting with the axis line of the one is made on a surface opposing to the other one, the one smoothly enters in the other one without scraping the softer opposing surface of the other one with the tongued and grooved part 4 and the tongued and grooved part 4 bits in the softer opposing surface of the other one, resulting in preventing from coming-out. <P>COPYRIGHT: (C)2007,JPO&INPIT |
