PROBLEM TO BE SOLVED: To extend the biting-in dimension for claws, and obtain a sufficient fitting strength by a method wherein at one part of the opening of a container, protruding claw parts are provided, and a protruding part which is fitted in the tip ends of the claw parts is formed on a lid, and the claw parts are slid to the protruding part, and pressed. SOLUTION: A protruding part 6 which presses the tip ends of claw parts 3, 3 protruding from a container 1 made of a thermo-setting resin is provided on a lid 2 made of a thermo-setting resin. Thus, the tip ends of the claw parts 3, 3 which are inserted from an insertion hole 9 of the lid 2, are slid to both sides and pressed by a tapered part 7 of the protruding part 6. For this reason, even when a flexible dimension of the claws is small, the biting-in of the corner parts 4, 4 of the claws to the corner parts 5, 5 of the lid 2 becomes larger, and a sufficient fitting strength can be obtained. In addition, by the protruding part 6 of the lid 2, the claws of the container 1 can be prevented from returning. |
