PROBLEM TO BE SOLVED: To standardize each combined and integrated connection structure of a body member as an outer shell body part and a hold member to a standard to give a general-purpose property. SOLUTION: A metallic material or a comparatively hard synthetic resin material is used as a constituent material for a body member 10, and a synthetic resin material which is slightly less hard than the above-mentioned material is used as a constituent material for a hold member 30. A fixed stepped part 19 in which a seal member 40 and a pressing member 45 are overlapped sequentially and are provided internally and a receive inner peripheral face 21 which is provided continuously with the fixed stepped part 19, is opened in an end part, and on which an engaging groove 23 is peripherally provided in a proper section are formed in an internal space 20 of the body member 10. An outer peripheral face fitted and inserted into the receive inner peripheral face 21 and an engaging rising bar fitted and engaged in the engaging groove 23 in a fitted and inserted condition are formed in the hold member 30 combined and connected with a connection opening end 22 in one end part of the body member 10. Furthermore, a pressing end face pressing and fixing the seal member 40 and the pressing member 45 which are internally provided in a fitted and inserted condition is formed. |
