The body 11 has a hole H, The insertion groove 15 into which the rims E of the ribs 15 are inserted is formed. A through hole (17) connected to the pleated hose (20) is formed in the body (11). The side wall 18 of the tee positioned at the front of the insertion groove 15 has an outer side surface 19 directed toward the rear side (toward the corrugated tube) so as to be easily inserted into the hole H, . That is, the thickness of the side wall 18 is formed to be thicker toward the outer side toward the rear side.

The cap 30 includes a body 31 formed to receive a door connector DC and a flange F of a door connector DC is formed on an inner side surface 33 of the body 31 An insertion groove 35 to be inserted is formed.

Generally, the door connector DC is formed to fit into the insertion groove 35 because the flange F is formed along the circumference of the front end.

The use of the background art will be described as follows.

The door connector DC is passed through the through hole 17 of the body 11 through the corrugated hose 20 and the cap L is connected to the door through the through hole 17 of the body 11, 30). Then, the head 10 is inserted into the hole H of the door from which the electric wire L is drawn out. The outer side surface 19 of the side wall 18 is inclined toward the outer side toward the rear side and the opening 13 is formed inside the side wall 18 so that the side wall 18 is inwardly H), and then expanded to the outside room in its original shape and restored. Then, the edge E of the hole H is fitted into the insertion groove 15 formed on the outer side of the side wall 18. [

Since the door connector DC is connected to the body connector BC, the mounting of the grommet 1 for the vehicle door is completed. At this time, the longitudinal section of the cap 30 comes into contact with the front surface of the main body connector BC .

The background art has the following problems.

First, when the vehicle door is opened to the maximum extent as required, the pleated hose 20 is pulled and the body 11 is pulled. There is a problem that the side wall 18 is detached from the hole H of the door while it is broken as shown in Fig.

Secondly, there is a problem in that during the rainfall or washing, water seeps between the longitudinal section of the cap 30 and the front surface of the main body connector BC, causing a short circuit.
