DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention applied to a battery type forklift, particularly a reach lift, will be described below with reference to the drawings. First, in FIG. 1, the reach lift lifts and lowers a cargo handling device 14 including a fork in front of a vehicle body 13 supported by wheels 11 and 12, and includes a mast device 15 capable of moving forward and backward in the longitudinal direction of the vehicle body 13. ing. The main body of the vehicle body 13 includes a rear driver's seat 16 and a front battery storage room 17. A hole 18 is formed in a side plate (outer body plate) 20 of the battery storage chamber 17, and a battery plug can be inserted and removed from the hole 18 when charging the battery. The battery plug door (hereinafter referred to as “closing door”) 19 allows the hole 1 to be closed.
8 is closed.

The structure of the closing door 19 will be described in detail with reference to FIGS. On the back surface (inside the vehicle body) of the closing door 19, the hinge portions 21a,
1b, and a stopper portion 22 is provided so as to be biased to the other side. The closing door 19 and the hinge 2
1a, 21b and the stopper portion 22 are integrally formed of a synthetic resin material. The hinge portions 21a and 21b are formed in a clip shape having an opening in a direction parallel to the closing door 19 (see FIG. 3). In this embodiment, the inner peripheral surface of the clip shape has an elliptical shape. The major axis of the ellipse is parallel to the closing door 19. The stopper 22 has a clip shape having an opening in a direction perpendicular to the closing door 19. The hinges 21a and 21b and the stopper 22
Round bar anchors 23 and 24 for mooring are respectively provided (see FIGS. 2 and 4). That is, the round bar anchor 2
3 and 24 are arranged at positions corresponding to the hinge portions 21a and 21b and the stopper portion 22, respectively, and their respective ends are fixed to the vehicle body outer plate 20 at the peripheral portion of the hole 18 by welding. Further, the hinge portion 21b protrudes downward by a dimension G of a holding gap between an inner peripheral edge of the hole 18 and an outer peripheral edge of the closing door 19, and the protruding portion is a lower end of the closing door 19. The lower edge of the hinge portion 21b is in direct contact with the inner peripheral edge of the hole 18 when assembled. Reference numeral 25 denotes a through hole through which an operator hooks a finger or the like when opening and closing the closing door 19.

Next, the operation of this embodiment will be described. The closing door 19 having the above-described configuration is attached to the outer plate 2 of the vehicle body 13.
When assembling to zero, the clip openings of the hinge portions 21a and 21b are pushed into and fitted to the round bar anchor 23 provided facing the hole 18. Next, the closing door 19 is rotated about the round bar anchor 23, and the clip opening of the stopper portion 22 is now
Is pushed into and fitted to the round bar mooring member 24 arranged facing the vehicle body, and the closing door 19 is fitted into the hole 18 so that the hole is flush with the vehicle body outer panel 20. 18 is closed. At this time, the downward projecting portion of the hinge portion 21b is
8 can be kept in contact with the inner peripheral edge of the closing door 19, and the gap between the inner peripheral edge and the outer peripheral edge of the closing door 19 can be kept constant.
The dimensional error of the distance between the round bar anchor 23 and the round bar anchor 24 can be absorbed by the inner peripheral surfaces of the elliptical clip-shaped hinge portions 21a and 21b. That is, at the position moved in the major axis direction of the ellipse by the dimension error, the round bar anchor 2
The mooring state is achieved in a state where 3 is held. When the closing door 19 is to be opened for charging or the like, if the operator puts a finger or the like in the through hole 25 and pulls it forward, the round bar anchor 24
Is stopped, the closing door 19 is rotated about the round bar anchor 23, and the hole 18 is opened. Further, when it is desired to remove the closing door 19 from the vehicle body outer panel 20, if the closing door 19 is continuously pulled in a direction parallel to the closing door 19, the hinge portion 21 is removed.
Since the mooring state of the a and 21b is released, the closing door 19
Is removed.

The effects that can be expected from the above embodiment will be described below.

(A) Since the closing door and various parts related to the closing door are integrally formed of a synthetic resin material, the number of parts can be reduced, thereby reducing costs and assembling man-hours. Can be reduced.

(B) The lower end of the hinge portion is projected downward by the amount of space between the inner peripheral edge of the hole formed in the outer panel of the vehicle body and the outer peripheral edge of the closing door. Since the holding gap can be maintained, the opening / closing operation of the closing door can be smoothly performed, and the holding gap can be kept constant, so that the appearance is excellent.

(C) Since the clip-shaped inner peripheral surface of the hinge portion has an elliptical shape, it is possible to absorb a dimensional error in manufacturing, whereby the closing and opening operations of the closing door can be performed smoothly. In addition, it is possible to prevent the closing door from being deformed due to an excessive force.

The present invention is not limited to the above embodiment, but can be implemented as follows. In the above embodiment, the present invention is applied to the battery plug door of a battery-powered forklift. However, the present invention can also be applied to a general vehicle and an inspection window or the like. Further, the present invention is not limited to the vertical side plate, and may be a slanted or horizontal body plate. However, in this case, as specified in claim 2, in addition to projecting the lower end of the hinge portion downward by the set size, the upper end (the other end) of the hinge portion also rises by the set size in the same manner. It is necessary to protrude from the outer peripheral edge of the closing door toward (the other end). In the above embodiment, the clip opening direction of the hinge portion is directed to the outer peripheral edge of the closing door, but the opposite direction may be directed to the center portion of the closing door. In the above-described embodiment, the lower end of the hinge portion is projected downward by the amount of the space between the inner peripheral edge of the hole and the outer peripheral edge of the closing door, and the lower end surface is brought into contact with the inner peripheral edge of the hole. However, apart from the hinge portion, at the outer peripheral lower end edge of the closing door, when the closing door pivots, the portion of the possessed gap is only partially near the inner peripheral edge of the hole at all times. The present invention can be implemented even if the protrusions are provided. In the above-described embodiment, the hinge portion is divided into two upper and lower portions. However, the number of hinge portions can be reduced to one or three or more. The embodiment of the present invention is possible even if the number is more than one.

[0021]

As described above, according to the present invention, since the closing door and various parts related thereto are integrally formed of a synthetic resin material, the number of parts can be reduced, thereby reducing costs. This has a remarkable effect that it is possible to reduce the number of assembly steps as well as to reduce the number of assembly steps.
