Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for positioning a windshield glass when disposing the windshield glass in an opening of a vehicle body.

[0002]

2. Description of the Related Art As shown in FIG. 5, a stopper 13 having a base 11 and a locking portion 12 fixed to the upper edge of an opening 10 for attaching a windshield glass of a vehicle body, and a stopper 13 are arranged in the opening 10. There has been proposed a windshield glass positioning device including a spacer 15 having a pawl portion 16 fixed to the lower surface of the windshield glass 14 (Japanese Utility Model Publication No. 3-42411).

In the above positioning device, the claw portion 16 of the spacer 15 has the locking portion 12 of the stopper 13 when the windshield glass 14 moves in the vertical direction orthogonal to the surface thereof.
It moves in the hole 17 provided in the. Then, when the pawl portion 16 abuts on the hole end, it prevents the windshield glass 14 from moving more than a predetermined amount in the vertical direction. Further, the contact surface 18 of the spacer 15 on which the pawl portion 16 is provided comes into contact with the locking portion 12 and prevents the predetermined movement or more when the windshield glass 14 moves downward along the surface. .. Thereby, the windshield glass is positioned.

[0004]

The amount of movement of the windshield glass 14 in the downward direction orthogonal to that surface is caused by the pawl portion 16 abutting against the prepared hole end of the hole 17 of the engaging portion 12, or Even if the hole 17 is extended to the base portion 11, the claw portion 16 of the spacer 15 is restricted by hitting the base portion 11, and the allowable amount of downward movement from the design level value of the windshield glass is small. Therefore, when a force in a direction orthogonal to the surface is applied to the windshield glass 14 in order to mount, for example, a wind molding before the urethane adhesive 19 is cured, a local stress is generated and the windshield glass 14 is Cracks may occur.

Therefore, it is an object of the present invention to provide a vehicle windshield glass positioning device capable of increasing the amount of downward movement of the windshield glass from the design level value.

[0006]

According to the present invention, there is provided a stopper having a base portion and a locking portion which are fixed to an upper edge of an opening for attaching a windshield glass of a vehicle body, and a windshield glass arranged in the opening portion. And a spacer fixed to the lower surface of the windshield glass. The spacer has a pawl portion that engages with the locking portion of the stopper and prevents movement beyond a predetermined value when the windshield glass moves in an upward direction orthogonal to the surface thereof. The base portion of the stopper has a driven inlet into which the pawl portion of the spacer can enter when the windshield glass moves in a downward direction orthogonal to its surface.

[0007]

When the windshield glass has a variation in the size in the downward direction orthogonal to the surface thereof, the claw portion of the spacer penetrates into the driven inlet of the base portion of the stopper to absorb the variation.

As a result of an increase in the allowable amount of downward movement from the design level value of the windshield glass, even if the windshield glass has a variation in the downward dimension orthogonal to its surface, the spacer and the stopper come into contact with each other. Can be substantially avoided. This makes it possible to prevent the windshield glass from being in a locally stressed state and prevent the windshield glass from cracking.

Since it is possible to prevent the windshield glass from being in a locally stressed state, the work of assembling the windshield after positioning the windshield glass can be carried out without requiring special skill, and workability is improved. Can be improved.
