抵抗が生じるので、大きな操作力量が必要であり、操作
性が悪かった。However, when the waterproof cap 30 is rotated at the time of attachment / detachment as described above, rotation occurs between the support cylinder 12 and the inner cylinder 31 that sandwich the O-ring 32. A strong tensile force acts on the O-ring 32 in the circumferential direction, and the O-ring 32 is broken or partially broken, which deteriorates the sealing effect and causes water leakage. In addition, since a large resistance is generated by the O-ring 32 during the rotating operation, a large amount of operation force is required and the operability is poor.

い。In this way, the waterproof cap 30 is attached to the electric connector 10, and the reverse operation is performed when detaching the electric cap 10. However, since the outer cylinder 33 is rotatable about the axis with respect to the inner cylinder 31, the electric connector 10 is rotated. It is not necessary to rotate the inner cylinder 31 at all when the waterproof cap 30 is attached to or detached from the inner cap 31.
