[Problems to be solved by the device]

 However, this conventional bush requires further improvement mainly in the following three points. First, in this conventional bush, a first bush having a first locking projection on the outside of the tubular locking portion and a second bush having a second locking projection on the inside of the tubular locking portion. Since the two bushes together form the bush, the first bushes or the second bushes cannot form the bushes. Therefore, it was necessary to take care not to select bushes that do not engage with each other when assembling the windshield. For example, consideration has been given to classifying both bushes and arranging them near the line, ensuring space for them near the line, and also color-coding both bushes separately. A solution was desired. Secondly, even if such consideration is taken, there is an inevitable inconvenience of selecting bushes that cannot be locked. Thirdly, dividing the bush member that constitutes the bush into two types of parts necessitates the production of two types of molds for the production of the parts, which impedes the cost reduction of this type of bush.

Therefore, the present invention solves the problem of the above-mentioned bush, that is, there is no possibility that bush members that do not engage with each other will be selected at the time of assembling the wind glass. The purpose of the present invention is to provide a bush made of bush members that can be produced at low cost without any consideration to prevent selection, and that are inserted into the mounting holes of the windshield and then locked with each other in the holes. is there.
