Next, attach the window glass 17 to each of the guide rails 18 and 1.
The rails 23 are lowered while being guided by 9, and / or the rails 23 are raised by the elevating mechanism 22, so that the rails 23 approach each other in the vertical direction.

At this time, the rail 23 is movable in the front-rear direction with respect to the front-rear rollers 43, 43. Therefore, the movement of the rail 23 causes the rail 23 to move in the front-rear direction of the vertical portion 59 of the notch 57. The position in the direction is made to coincide with the bolt 33, and the bolt 33 is further brought close to the bolt 33.

Then, the bolt 33 causes the vertical direction portion 5 to move.
It is inserted in 9 and guided. Next, by moving the rail 23, the bolt 33 and the laterally facing portion 58 of the notch 57 are fitted to each other, so that the bolt 33 moves into the bolt hole 3.

The rear lower end and the rear of the rail 23 are fastened together. Then, the assembling of the window glass 17 and the rail 23 of the elevating mechanism 22 is completed.

That is, according to the above construction, when the window glass 17 and the rail 23 of the elevating mechanism 22 are assembled, the positioning of the window glass 17 and the rail 23 with respect to each other is simply performed by simply bringing them close to each other. It will be possible by work.

Therefore, the work of assembling the window glass 17 and the rail 23 with each other can be easily performed.

Although the above is based on the illustrated example, the rail 23 and the front and rear brackets 24 and 25 may be integrally formed with each other, and the notch 57 is replaced with the front bracket 24. Alternatively, it may be formed on the rear bracket 25 together with this, and in this case, the same effect as the above can be obtained. Further, the window glass 17 may be directly supported on the stationary side of the vehicle body 1.
