Description

TECHNICAL FIELD The present invention relates to a seal structure for a swing wing vehicle, and more particularly to a seal structure for sealing a gap between a wing and a swing.

(Prior Art) Conventionally, at least a part of a roof and a part of a side wall of a box-shaped carrier are configured by wings having an L-shaped cross section, and a lower part of the side wall of the box-shaped carrier is configured by a tilt, and a roof of the wing is formed. BACKGROUND ART There is known a swinging wing vehicle capable of opening and closing a side portion of a box-shaped luggage carrier by rotation around a side end portion and rotation around a lower end portion of a tilt.

By the way, in this type of swing-equipped wing vehicle, while the wing is rotated downward about its rotation axis, the swing is rotated upward about its rotation axis,
The side of the box-shaped carrier will be closed.However, when the side of the box-shaped carrier is closed, it is unavoidable that there is a gap between the lower end of the wing and the upper end of the tilt. If left unattended, rainwater or the like may enter the inside of the box-shaped cargo bed through the gaps and contaminate the cargo. Therefore, in such a swing-equipped wing vehicle, generally, a lower end member having a blind portion that covers the upper outer surface of the swing is provided at the side wall side end of the wing, and the first lower end member provided on the lower surface of the lower end member is generally provided. The rubber seal member is elastically brought into contact with the upper end surface of the tilt, and the second rubber seal member provided on the inner side surface of the blind end portion of the lower end member is elastically brought into contact with the upper outer surface of the tilt so that the wings It is practiced to seal the gap between it and the tilt.

(Problem) However, in such a seal structure for a swinging wing vehicle, the conventionally proposed first and second rubber seal members are not necessarily suitable for such a seal structure, and the seal function and the seal are not necessarily required. The reality is that it is difficult to say that the function sustainability is sufficiently satisfactory.

For example, in the seal structure disclosed in Japanese Utility Model Laid-Open No. 59-112232, the first rubber seal member has a thick hollow structure, while the second rubber seal member has a thick flat plate structure. The first rubber seal member is elastically brought into contact with the upper end face of the tilt on the flat surface formed on the lower surface thereof, while the second rubber seal member is tilted on the flat surface on one side of the flat plate portion. The upper outer surface is elastically abutted to seal the gap between the wing and the tilt, but both the first and second rubber seal members having such a structure are The rubber is easily deteriorated by compression fatigue at an early stage and is likely to be permanently deformed into a compressed shape, so that the sealing function of these rubber seal members is likely to be damaged at an early stage.

(Solution) Here, the present invention has been made in view of such circumstances, and the gist of the present invention is to provide the first rubber seal member in the seal structure of the swing wing vehicle as described above. A hollow portion fixed to the lower end surface of the lower end member, and a tongue portion of a predetermined length that extends obliquely downward from the inner portion of the lower surface of the hollow portion toward the outside of the box-shaped carrier. The second rubber seal member has a flat plate-like fixed part fixed to the blind part of the lower end member, and obliquely upward and obliquely downward from the fixed part toward the inside of the box-shaped carrier. And a pair of tongue pieces extending in an inverted eight-shape, and the tongue pieces of the first rubber seal member in a state in which the sides of the box-shaped carrier are closed by the wings and the tilt. However, between the bottom surface of the lower end member and the above The second rubber seal member is elastically pressed against the upper outer surface of the tilt at the pair of tongue pieces while the upper and lower surfaces of the tilt are elastically pressed while compressing the empty portion vertically. I have done so.

(Operation / Effect) According to such a seal structure, the tongue portions of the first and second rubber seal members are respectively deformed in the shearing direction to contact the contact surfaces of the corresponding tilts. Since the tongues are brought into contact with each other, the tongue portions are not deteriorated early due to compression fatigue, and therefore, it is also preferable that the sealing function of each of the first and second rubber seal members is early deteriorated. It is avoided by.

Moreover, in the seal structure according to the present invention, the tongue piece is extended from the lower surface of the hollow portion of the first rubber seal member, and the tongue piece portion compresses the hollow portion between the lower end member and Since the tongue piece is pressed against the end surface, the tongue piece is pressed against the upper end surface of the tilt with a sufficiently large pressing force due to the compressive deformation of the hollow part, and thus the tongue piece and the tilt An excellent sealing function is obtained between the end face, that is, between the first rubber seal member and the upper end face of the tilt.

Further, in the seal structure according to the present invention, the second rubber seal member is brought into contact with the upper outer surface of the tilt by the two upper and lower tongue portions, and the second rubber seal member and the upper outer surface of the tilt are separated from each other. Since the sealing function is doubly exerted between them, an excellent sealing function can be obtained even between the second rubber sealing member and the upper outer surface of the tilt.

Thus, according to the seal structure according to the present invention, the early deterioration of both the first and second rubber seal members can be satisfactorily avoided, and the gap between the first rubber seal member and the upper end face of the tilt is prevented. , And between the second rubber seal member and the upper outer surface of the tilt, an excellent sealing function can be obtained. Therefore, the gap between the wing and the tilt can be sealed with excellent sealing performance and over a long period of time.
