The left and right front wheels 23 are rotatably provided in the portion 22, and the left and right two rear wheels 24 are rotatably provided in the traveling device body 21. A steering handle 26 is attached to a turning shaft 25 of the steering section 22 by a pin 27. By operating the handle 26 to turn the front wheel 24, the traveling direction of the traveling device main body 21 is changed in the left-right direction. be able to. By swinging the handle 26 about the pin 27, the vertical position of the distal end of the handle 26 can be arbitrarily adjusted according to the height of the operator's hand.

In the illustrated embodiment, the front wheels 23
And two rear wheels 24 are provided, but one of the front wheel 23 and the rear wheel 24 may be one wheel. Further, although the steering section 22 is provided in front of the traveling device main body 21, it may be provided in the rear.

A heating coil 31 is provided in a spiral shape on a heating surface of the traveling device main body 21 facing the floor plate 13, and a ferrite 32 is fixed to the back side of the heating coil 31. A pusher 33 is incorporated in the traveling device main body 21 to apply a pressing force toward the floor plate 13 to the heating coil 31.

As the pressing device 33, a coil spring is provided in a cylinder to apply a pressing force to the heating coil 31, or a pressing force is directly applied by using an elastic body such as a spring or rubber without using a cylinder. Or a pressing force may be applied using a pneumatic cylinder or a hydraulic cylinder.

One of the front wheel 23 and the rear wheel 24 has
A driving device such as a motor is connected, and the traveling device main body 21 can be automatically driven by the motor. However, the operator can hold the handle 26 and run without incorporating the driving device. You may do it.

A power supply unit 34 having a transformer for transforming a commercial power supply to reduce the voltage and a rectifier for rectifying an alternating current from the transformer to a direct current is connected to the traveling device main body 21 via a cable 35.

A high-frequency generator for generating a high-frequency current of a predetermined frequency, for example, about 20 to 30 hHz from a direct current from the power supply unit 34 is provided in the traveling device main body 21, and the high-frequency current is supplied to the heating coil 31. Has become. The magnetic field supplied to the heating coil 31 and generated in the heating coil 31 passes through the ferrite 32, so that the magnetic field does not enter the traveling device main body 21.

The floor plate 13 shown in FIG. 1 has an adhesive layer 1 on both sides.
The conductive sheet 15 formed with the conductive sheets 4a and 14b is used to adhere to the floorboard base 12. However, a conductive powder such as iron powder is used as a conductive heat generating member, and the conductive powder and the adhesive are used. The mixture may be interposed between the floorboard 13 and the floorboard base 12. Further, instead of the conductive sheet 15, a mesh-shaped member formed by knitting a conductive wire may be used as the conductive heating member.
