One of the pipe and a shaft portion of the operation member inserted into the pipe has a first annular contact surface, and a second annular contact surface that have different diameters A packing capable of elastic deformation and configured to effect waterproofing between the pipe and the shaft portion is mounted. In operation, the packing is selectively brought into contact with the first and second contact surfaces such that the packing is pressed harder on one of the first and second contact surfaces than on the other.
