8A is a plan view of the lift truck 51, FIG. 8B is a side view, and FIG. 9 is a rear view. A lift truck 51 of this type includes a carrier 53 including a pair of forks 52, and a vehicle body 54 having a driving device for driving the carrier 53 capable of moving up and down.
And a rod-shaped handle 56 and the like provided on the rear side of the vehicle body 54 so as to be tiltable around a shaft 55.

The lift truck 5 is provided above the handle 56.
An operation unit for moving the vehicle 1 and operation buttons for raising and lowering the loading platform 53 are arranged. As shown in the figure, the brake is applied between the state where the handle 56 is standing and the state where the handle 56 is laid down, and the brake is released between a certain position and the brake in an intermediate position. It has become.

A cover is provided on the upper and side surfaces of the vehicle body 54 so as to be openable.
It is composed of a top cover 60 and left and right side covers 61 and 62. The upper surface cover 60 is configured such that the handle 56 side is opened at a hinge portion, and the side covers 61 and 62 are double-opening type in which the back side of the vehicle body 54 is opened at the hinge portion at the side of the vehicle body 54. It has become.

[0005]

During maintenance of the vehicle body 54, the top cover 60 and the side covers 61, 6 are provided.
2 are respectively opened, and the cover 60 to 6 can be opened and closed on the upper surface and the left and right side surfaces.
When opening and closing the handle 2, the handle 56 must be tilted. Therefore, there is a problem that a large space is required behind the lift truck 51 during inspection and maintenance.

The top cover 60 can be opened and closed, but each time the top cover 60 is opened and closed, the battery capacity meter 63
It is necessary to attach and remove electric wires of instruments such as, and it is necessary to perform a process for preventing the electric wires after closing the top cover 60 and the side covers 61 and 62 from being attached to a movable device such as a drive device. It is difficult to do this reliably. This is because the upper and lower cover 60 is the first and last in the opening and closing procedure at the time of opening and closing the cover, so that the state of the electric wires after the upper cover 60 is closed cannot be confirmed. In addition, there were cases where instruments such as a battery capacity meter could not be attached due to these reasons.

Further, as shown in FIG. 8 (b), since the upper surface cover 60 is inclined so as to descend toward the handle 56 as shown in FIG.
In order to match the three surfaces of the three members 1 and 62, the accuracy of a single product is required, and the mounting portion (sheet metal welded portion) on the vehicle body also requires the accuracy. For this reason, the cost is high. To compensate for this, the gap between the covers 60 to 62 is made large to reduce the sheet metal accuracy and reduce the cost. However, for this reason, a gap between the covers 60 to 62 is inevitably generated, and there is a problem that the waterproofness is deteriorated accordingly.

The present invention has been made in view of the above points, and has a cover composed of two members, which facilitates attachment / detachment of the cover without falling down of the handle, and a wide space for opening / closing the cover. It is an object of the present invention to provide a lift truck which eliminates the need to secure the lift truck.

[0009]
