<Prior art> As is well known, vehicles such as automobiles have a part to which a windshield glass is fixedly attached to the window, and usually an elastic strip-shaped dam made of rubber or the like is attached around the inner outer periphery of the windshield glass. An adhesive is provided on the outside of the dam, and the dam is used to prevent the adhesive from leaking into the interior and preventing precipitation from flowing in.

However, the attachment of the dam to the windshield glass is done by hand, and the attachment work using a simple jig is done manually, which requires a considerable amount of technique and must be done by an experienced person, which makes mass production difficult. It was unsuitable, and there was a problem that the accuracy was not always constant.

To deal with this, for example, as shown in the figure, the holder bracket 4 is engaged with the chain loop 3 stretched over the sprocket 1 and the chain tensioner 2, and the roller 6 is attached to the guide rail 5. The dam 10 is rolled and rolled along the end surface of the windshield glass 7 set on a predetermined support base, and the dam 10 is fed out to the dam holder 9.
An adhesion device has been devised in which the adhesive is adhered to the edge of the windshield glass 7 via a dam guide 11 by a presser roller 12, and the peeled residue 13 is taken up by a take-up roller 14.

<Problems to be Solved by the Invention> However, the bonding of dams using the seed bonding device is limited in the types of windshield glass, lacks compatibility with various types of glass, requires multiple types of devices, and is costly. Not only does this have advantages, but it also has the disadvantage that it is difficult to completely eliminate variations in bonding positions due to the cam copying method, making it difficult to obtain stable quality.

The object of the present invention is to solve the technical problem of adhesion of a dam to the windshield glass of a vehicle based on the above-mentioned prior art, and to detect the position of the windshield glass on the holding stand installed in the frame, and to detect the position of the windshield glass on the holding stand installed in the frame.
