Description of the Related Art In an electric vehicle operated by an operator who is not in the vehicle, a steering wheel operation such as an operation of pushing or pulling a gate-shaped operation handle of the electric vehicle is detected by the operator. However, there is a configuration in which when the steering wheel operation is detected, the electric motor outputs the electric power to drive the vehicle.

る。However, when the above-mentioned folding is realized by detaching the operation handle from the body frame, not only the pushing force of the operator but also the weight of the occupant seated on the seat is exerted on the operation handle. Therefore, there is a concern that the rigidity of the operating handle is insufficient, that is, the operating handle is easily deformed. This is because, since the frame is foldable, when the occupant sits on the seat, the left and right frames are slightly tilted inward, and as a result, weight is added to the operation handle. In particular, when the steering wheel operation is detected, if the rigidity of the steering wheel is insufficient, there is a concern that the detection accuracy of the steering wheel operation cannot be sufficiently obtained.

As a result, a substantially rectangular shape that is long in the vehicle width direction is formed as a whole, and as a result, the rigidity of the entire operation handle 3 can be increased, and the deformation of the operation handle 3 due to the operation force or the weight of the occupant can be suppressed, and the operation force can be reduced. It is possible to improve the detection accuracy of.

The oblique side is formed, and the reinforcing pipe 23 forms the bottom side. Also from this point, the rigidity of the entire operation handle 3 can be increased. In addition, the left and right grips 31, 31 of the operation member 20 have the apex at the center in the vehicle width direction,
Since the right hypotenuse is formed, the helper can easily grip the grips 31, 31 and improve the operability.

きる。Furthermore, when viewed from the rear side, the brake lever 34 is located above the reinforcing pipe 23 and is a part of the operating member 20 and the grip 31 forming the oblique side.
Since it is located on the front side of the grip 31 and overlaps with the grip 31, it is easy to operate the brake lever 34 while holding the tilted left and right grips 31, 31, and
The brake lever 34 and the hand holding it are the reinforcement pipes 2.
3 does not interfere, and the operability can be improved also from this point.

Since the inner member 24 is connected to the inner member 24 by the outer member 25 so as to be relatively movable,
4, the frame member 21, 21 and the reinforcing pipe 23 can form the above-described rectangular shape in plan view to increase the rigidity as a whole. Since the external member 25 is movable relative to the internal member 24 having a rectangular shape having high rigidity, the operating force is detected by the relative movement.
The accuracy of detecting the operating force can be improved.
