Abstract

PROBLEM TO BE SOLVED: To prevent the separation of a lid part even against strong external force by bringing jaw parts into contact with the lower part of the fitting part of the back plate of an insertion hole by a pair of engaging piece parts to hold fitting and bringing the side wall inner surface of a seal stopper or a seal stopper part into contact with a pair of the engaging piece parts from both sides to engage the same with them. SOLUTION: An engaging groove 141 extending in a longitudinal direction is formed to the lower end part of the insertion piece part 140 of a lid part 100 to provide a pair of engaging piece parts 142, 143 branched in a bifurcated state. Jaw parts 144, 145 protruding in a mutually approaching direction are formed to the mutually opposed inside side surface parts of a pair of the engaging piece parts 142, 143. A fitting part 242 having a flange part 243 provided to the leading end thereof and permitting a pair of the engaging piece parts 142, 143 to fit is provided to the back plate 241 of the insertion hole 240 of a cap main body 200. A seal stopper 300 is formed into a recessed shape consisting of a peripheral wall having side walls 311, 312 and a bottom wall 320. The insertion piece part 140 is inserted in the insertion hole 240 to be attached to the cap main body and the insertion hole 240 is covered with the seal stopper 300 from below to produce a hinge cap 10.
