<p>PROBLEM TO BE SOLVED: To increase a sealing performance between a joint main body and a cap, and also confirm the degree of cap screwing. SOLUTION: An electrodepositing branch connection 1 comprises a joint main body 2 which is provided with a drilled hole 21, branch pipe takeout port 22, and a saddle part 23 in the internal surface of which a heating wire is buried and a cap which is provided with a female screw 33 to be screwed into a male screw 27 provided on the joint main body and plugs the drilled hole 21. Also a first O-ring 5 which is brought in pressure contact with the upper end surface 26 of the joint main body for sealing is installed on the inner bottom part 31 of the cap, and a second O-ring 6 which is brought in pressure contact with the inner peripheral surface 34 of the cap for sealing is installed on the body part 25 of the joint main body. Thus, when the cap 3 is screwed into the joint main body 2 and the second O-ring is hidden inside the bottom end 32 of the cap and becomes invisible, the first O-ring 5 is also sealed.</p> |
