A cover made of a joining member made of synthetic resin filled between the member 43 and the outer circumference of the cover member 43 and the circumference of the opening 20 described above so that water does not smudge between them. Is formed in the area between the two members including the distal end portion 53, which is fitted to the opening portion 20 of the case body 11 and the two members in the fitted state and the elasticity within the defect A detection switch case and a method for manufacturing the same, wherein the elastic bonding member 55 made of synthetic resin is disposed in a charged state.

4.발명의 중요한 용도.4. Significant uses of the invention.

방수성을 확실히 유지할 수 있음과 동시에 케이스의 강도를 높일 수 있다. 또한 케이블을 방수하기 위한 특별한 케이부쉬부가 줄어들어서 제조공정수가 증가하는 일도 없다.The waterproofness can be maintained securely and the strength of the case can be increased. In addition, there is no increase in the number of manufacturing processes due to the reduced number of special k-bush parts for waterproofing cables.
