摘要： PROBLEM TO BE SOLVED: To obtain improvement of falling-out preventing force of a seal cap and facility of attaching and removing work at the same time.
SOLUTION: The seal cap 7 has a closing part 11 fitted in an intake port 3 and a discharge port 5 under pressure. The closing part 11 is pressed against inner wall surfaces of the intake port 3 and discharge port 5 with its own elasticity. An expansion part 14 is then reduced in diameter by closing a pair of handles 15 of a clip 8 and is fitted in a concave part 12 of the seal cap 7. When the handles 15 are released, the expansion part 14 is expanded and its outer peripheral surface presses an inner peripheral surface of the concave part 12. Strong falling-out preventing force of the seal cap 7 is generated by multiplier effect of elastic force of the closing part 11 and biasing force of the expansion part 14. When the seal cap 7 is removed, contact pressure against the inner peripheral surface of the concave part 12 is relaxed by closing the handles 15 to reduce the diameter of the expansion part 14 and the clip 8 can be simply removed. The seal cap 7 can be easily removed by gripping a knob part 10 and pulling up it.
