Further, on the front side of the handle post 26 of the electric vehicle 10, a front basket 45 as a box-shaped storage basket is attached at a position lower than the handle unit 30 via upper and lower support brackets.

On the other hand, the handle unit 30 of the electric vehicle 10 is provided with a cover 47 so as to cover the upper part of the accelerator lever 33. As shown in FIG. 2, the cover 47 is composed of a rectangular plate that cantilevers protrude outward from the operation box 31 of the steering wheel unit 30 to the left and right sides in the vehicle width direction. The cover 47 is preferably composed of a transparent or translucent resin plate.

The handlebar 32 extends outward on both the left and right sides (in the vehicle width direction) at the front portion of the operation box 31, and bends in the front-rear direction from both the left and right outer ends, and from the front end portion of the bent portion. The steering wheel is composed of a grip portion extending inward in the vehicle width direction. The grip portion of the handlebar 32 is a rear side portion of the operation box 31 of the vehicle, and the handle shafts are arranged on both the left and right sides of the vehicle in a substantially linear manner in the horizontal direction of the vehicle.

The accelerator lever 33 constitutes the main part of the accelerator device 50 of the electric vehicle 10. The accelerator lever 33 is provided so as to project in a crank shape from both the left and right sides of the operation box 31 in the vehicle width direction. The accelerator lever 33 is located near the front side of the vehicle in the grip portion. The lever operating portion 51 forming the tip portion of the accelerator lever 33 is arranged in a substantially parallel relationship with the grip portion (grip shaft) of the handlebar 32. In the handle unit 30, the driver puts his / her hand on the grip portion of the handlebar 32 and pushes down the operation portion 51 of the accelerator lever 33 while grasping the grip portion (as shown from the solid line position A to the chain line position B in FIG. 3). The electric vehicle 10 is driven by operating the lever (rotating from top to bottom).

When the driver releases the lever operating portion 51 of the accelerator lever 33, the accelerator lever 33 is automatically returned to the solid line position A (original position) by the spring-forced force of a spring (not shown), and is braked and stopped. It has become.

By the way, the accelerator device 50 of the electric vehicle 10 is configured as shown in FIG. In the accelerator device 50, each output signal of the forward / backward changeover switch 35, the adjustment dial 36, and the accelerator lever 33 is input to a travel control unit 52 such as a CPU.

In addition, the cover structure that covers the upper part of the accelerator lever 33 reliably prevents the electric vehicle 10 from accidentally traveling due to unintentional contact with a third party such as a driver or a caregiver, or an object around the steering wheel. can do. Since the electric vehicle 10 has a cover structure that covers the upper part of the accelerator lever 33, access to the accelerator operating portion is restricted, so that there is an effect that the driver can be instructed to operate the accelerator lever 33 in the correct riding posture.

[Action of the first embodiment]
Next, the operation of the accelerator device of the electric vehicle will be described.

When operating the accelerator device 50 of the electric vehicle, the driver sits on the seat 22 of the seat 21 of the electric vehicle 10 shown in FIG. 1 and operates the switches of the operation box 31. The forward / backward changeover switch 35 switches between forward and reverse, and the dial operation of the adjustment dial 36 adjusts the forward travel speed to the required speed in several stages, for example, in the range of 2 km / hour to 6 km / hour. Set. Then, by turning on the key switch 44, the vehicle's preparation for running is completed.

When the vehicle is ready to run, the driver inserts his hand through the gap between the grip of the handlebar 32 (of the steering handle) behind the steering wheel unit and the cover 47, as shown in FIGS. 5 and 6. , Grip the grip and access the accelerator lever 33. The handle unit 30 has a space in which a hand for operating the accelerator lever 33 from the direction of arrow P can be inserted. Then, as shown in FIG. 6, the driver pushes down the lever operation portion 51 of the accelerator lever 33 with the index finger and the middle finger of the hand while holding the grip portion of the handlebar 32, so that the accelerator lever 33 is the handlebar 32. It rotates around the grip part of the vehicle and is pushed down from the top to the bottom, and the vehicle starts running.

When the driver releases the lever operating portion 51 of the accelerator lever 33, the accelerator lever 33 automatically returns to the original position (solid line position A in FIG. 3) by the restoring force of the spring, and the vehicle is stopped.

In the first embodiment, the accelerator lever 33 is configured in a crank shape, but if the lever is arranged side by side in the vicinity of the grip portion on the handlebar 32 and is pushed down, the accelerator lever 33 The bar shape is not limited to the crank shape, and various shapes can be considered.
