定の位置に保持される。 The method of assembling the plug 35 according to the present invention described above is as follows: First, use the fingers of your hand to press the pair of diametrically opposed upper protrusions 44 and the center axis 46 from the outside.
Transform it in the direction that approaches it. Next, the lower protrusion 44 is brought into contact with the bottom surface of the open top recess 33 to deform the lower protrusion 44 in a direction toward the central axis 46. Since the plug 35 is made of an elastic material and is provided with the slit 52, each protrusion 44 is easily deformed in a direction toward the central axis 46. Release the finger after each protrusion 44 enters the open top recess 33. Each protrusion 44 tends to return to its original state due to its elasticity, so that each protrusion 44
is brought into elastic contact with the wall surface of the top open recess 33. Next, the entire plug 35 is pushed into the top open recess 33 , the protrusion 48 of each protrusion 44 is engaged with the circumferential groove-shaped recess 51 , and the channel-shaped guide 60 is inserted into the top open recess 33 . Fit into the open top 42. In this way, plug 35
is attached to the top open recess 33. At this time, each protrusion 44 has a top open recess 33 due to its elasticity.
The hollow body 36 is held in place by being pressed against the wall of the hollow body 36.
