2. Description of the Related Art Conventionally, as a mounting structure for a front lid of this type, as shown in FIG. 4, a frame member 2 is provided at a front portion of a bus so as to extend in a vehicle width direction, and a front outside constituting a front surface of the bus. The front surface of the skeletal member 2 is covered with the outer plate main body 4a of the plate 4, and a through hole 4b is formed substantially at the center of the outer plate main body 4a.
Further, the upper rear surface of the front lid 9 for closing the through hole 4b so as to be openable and the surface of the outer plate body 4a are connected to the hinge arm 6.
There is known a mounting structure for a front lid connected by a front lid. In the mounting structure of the front lid, the base end of the hinge arm 6 is mounted on the upper back surface of the front lid 9, and the hinge bracket 7 is mounted on the surface of the outer plate body 4a above the through hole 4b. A hinge pin 8 is attached to the hinge bracket 7 so as to extend in the vehicle width direction. A tip of the hinge arm 6 is attached to the hinge pin 8 so as to be rotatable. The hinge bracket 7 has a function as a grip that can be gripped by hand. Further, a flange portion 4c is formed at the upper edge of the through hole 4b, and the base end of the water guide member 3 having a substantially U-shaped cross section, the tip of which is in close contact with the back surface of the front lid 9, is attached to the flange portion 4c.

When cleaning the glass 5b fitted in a, the operator can support his / her own body by gripping the hinge bracket 7 (grip), so that the glass 5b can be cleaned in a stable posture. Further, rainwater or the like flowing down the surface of the outer plate body 4a accumulates in the water guide member 3, flows along the water guide member 3, and is discharged from drain holes (not shown) on both sides of the through hole 4b. You. As a result,
The inside of the bus does not get wet with rainwater.

[0004]

However, in the above-described conventional front lid mounting structure, an excessive load is applied to the front lid because the front lid is supported by the relatively low-strength outer plate body via the hinge arm. When acting on a hinge arm or a hinge arm, the outer plate body may be deformed.
Further, in the above-described conventional front lid mounting structure, the hinge bracket and the hinge arm are exposed, which impairs the appearance and restricts the mounting position of the glass cleaning grip. Also, with the above-mentioned conventional front lid mounting structure, in order to reduce the number of machining steps for parts,
Although it is preferable to manufacture hinge brackets and hinge arms by aluminum die casting, if the model of the bus is changed, the shape does not match, the conventional hinge brackets cannot be used, and expensive aluminum die casting metal is used. A new mold has to be manufactured, which raises the problem of increasing the manufacturing cost. Furthermore, in the above-mentioned conventional front lid mounting structure, since the hinge arm projects from the rear surface of the front lid to the surface of the front outer plate, it is necessary to cut out the water guide member at the portion where the hinge arm penetrates. There was also a problem that the sealing performance against rainwater and the like was impaired.

A first object of the present invention is to lift up the front lid or hinge arm so that the mounting portion of the front lid is not deformed even when an excessive load is applied to the front lid or the hinge arm. An object of the present invention is to provide a mounting structure for a front lid. A second object of the present invention is to provide a flip-up front lid capable of mounting a glass cleaning grip at a position suitable for the cleaning operation, regardless of the mounting position of the hinge arm, without impairing the appearance of the front of the vehicle. An object of the present invention is to provide a mounting structure. A third object of the present invention is to provide a mounting structure for a flip-up front lid that can open the front lid with a relatively large opening. A fourth object of the present invention is to suppress an increase in manufacturing cost even if a model change of a vehicle is performed, and to reliably prevent rainwater or the like flowing down the surface of the outer panel body from entering the vehicle. It is an object of the present invention to provide a flip-up front lid mounting structure that can be mounted.
