It is generated according to the offset amount X ₁ between the pin 8 and the end 5R,
These forces are expressed as follows.

F ₁ · X ₁ ≦ F ₂ · X ₂ = μF ₁ · X ₂ (2) Here, μ is the friction between the bottom plate 5 A and the contact surface of the body 2 as in the above formula (1). It is set to a predetermined value according to the coefficient, and in order to maintain the balance of the moment, this inter-surface friction coefficient μ must be maintained.

Therefore, when the bottom plate 5A and the body 2 are brought into contact with each other by interposing the seat surface seal 110 as in the above-mentioned conventional example, the space between the surfaces depends on how the seat surface seal 110 is applied, for example, the application thickness. Although the coefficient of friction μ varies, as in the present embodiment, the bottom plate 5A and the body 2 are directly brought into contact with each other, and the seal 10 for adhesion and rust prevention is formed on the body 2 side.
By applying the female hinge 5 after applying it to 2, 23, it is possible to prevent the seal 10 from flowing into the groove 22, 23 and keep the inter-surface friction coefficient μ constant. The balance of the moment can be maintained, the female hinge 5 constituting the lower hinge 4 can be surely prevented from rotating, and the displacement along the body 2 can be prevented, so that the door 1 can be quickly moved to a predetermined position. In the above-mentioned conventional example, an adhesive seal 110 is entirely applied between the body 2 and the female hinge 95, and a rust preventive seal 111 is further provided along the end portion 95R. Although it was applied, in the present invention, the groove 2 near the end 5R of the bottom plate 5A is used.
Since it is sufficient to apply the seal 10 only to the Nos. 2 and 23, the seal 10 of the groove 22 performs adhesion and the seal 10 of the groove 23 performs rust prevention, the amount and type of the seal used can be reduced as compared with the conventional example. As a result, the reduction of manufacturing cost can be further promoted.

Further, in the above embodiment, the case where the bottom plate 5A is extended to the rear of the vehicle body is shown, but as shown in FIG. 4, as in the above embodiment, the "U" shaped reinforcing portion 53 is provided. Instead of providing it, the protrusion 50 may be a female hinge 5'which rises from the end 5R 'of the bottom plate 5A in the same manner as in the conventional example, and in this case also, the end 5R pin is formed in the same manner as described above. By setting the ratio of the offset amount X ₁ and the protrusion amount Y ₁ of 8 in the same manner as in the above formula (1), it is possible to prevent the door 1 from rotating during assembly and improve productivity and quality at the same time. It becomes.
