In a seal structure that seals between a hinge portion 12 to which a front lid 11 is rotatably attached and an end finisher 15, a sealing material 14 through which the hinge 12 penetrates has a front side A that is long and a back side B that is short. The overall horizontal cross section is trapezoidal, and has an engaging portion 3 that engages with the upper edge of the front lid at the upper part of the surface on the front side A. A flange 4 protruding rearward is provided on an upper part of an inclined surface 5 connecting the surface of the side B.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seal structure that seals between a hinge part to which a front lid is rotatably attached and an end finisher.

[0002]

[Prior art]

 For example, as shown in FIG. 3, a front lid 11 that rotates in the F direction by a hinge 12 is attached to the front surface of the cab C, corner panels 16 and 16 are attached to both sides of the front lid 11, and an end portion is provided above the front lid 11. A technique is known in which the finisher 15 is provided and the front lid 11, the corner panel 16 and the end finisher 15 are sealed with a sealing material 14.

The sealing material 14 is formed of, for example, with reference to FIG. 4, a hollow portion 14a, a lip portion 14b, and an engaging portion 14c that engages with the upper edge of the front lid 11.

Further, at a portion where the hinge 12 crosses the sealing material 14, referring to FIG. 5, a hinge seal 13 penetrates and is attached to an arm 12 a of the hinge 12, and engages with an upper edge of the front lid 11. It is configured to engage with the portion 13a and come into contact with the sealing material 14.

[0005]

[Problems to be solved by the device]

 However, at the intersection of the seal material 14 and the hinge arm 12a, the seal material is pushed more than other parts and is crushed, so that there is a problem that the seal is insufficient and the appearance is different. is there.

Therefore, it is an object of the present invention to provide a seal structure for a hinge part of an openable front lid that prevents water from entering through the hinge part of the openable front lid.

[0007]

[Means for Solving the Problems]

 According to the present invention, in the sealing structure that seals between the hinge part to which the front lid is rotatably attached and the end finisher, the sealing material through which the hinge penetrates has a long front side and a short back side, and has a horizontal cross section as a whole. It is trapezoidal and has an engaging part that engages with the upper edge of the front lid at the upper part of the front side surface, and the upper part of the rear surface and the inclined surface connecting the front surface and the rear surface. There is a flange that projects rearward.

[0008]

[Action]

 In the seal structure of the hinge part of the retractable front lid configured as described above, the hinge seal through which the hinge arm penetrates has a long engaging part on the front side for engaging with the front lid and A flange is provided on the upper part of the connecting slope.

Therefore, even if the sealing material is pushed on the short back side, the sealing line on the upper end of the lid is continued at the long engaging portion, and the flange engages with the sealing material on the rear side to prevent further intrusion of water. Be done.

Since the sealing line on the upper edge of the lid is continued, the appearance is improved.

[0011]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the drawings, members having the same function are designated by the same reference numerals, and description thereof will be omitted.

In FIG. 1, the hinge seal 1 is an elastic body (for example, rubber) and is formed so that the front side A is long and the back side B is short and the horizontal cross section is trapezoidal.

In addition, a hole 2 through which a hinge arm (not shown) penetrates is provided substantially in the center of the trapezoid, and an upper surface of the front side A is also referred to in FIG. An engagement portion 3 that engages with the end is provided.

A flange 4 protruding rearward is provided on the inclined surface 5 connecting the surface on the front side A and the surface on the back side B and the upper part of the surface on the back side B.

In the hinge seal 1 thus configured, the hinge arm 12 a penetrates the hole 2 and the engaging portion 3 is attached so as to engage with the upper end of the front lid 11.

Therefore, even if the sealing material 14 attached to the lower portion of the end finisher is crushed by the short surface on the back surface side B, the flange 4 of the inclined surface 5 contacts the sealing material 14, so that intrusion of water is prevented. Since the long engaging portion 3 engaging with the front lid 11 covers the deformed portion of the seal material 14 and connects to the undeformed portion of the seal material 14, the invasion of water is primarily prevented. And improve the appearance.

[0018]

[Effect of device]

 Since the present invention is configured as described above, the engaging portion of the hinge seal prevents water from entering and enhances the appearance from the front, and the flange of the inclined surface engages with the seal material. It secondarily blocks the infiltration of water and improves the water honey.
