The elastic body is to connect the front / rear plates (100,200), in one embodiment of the present invention is made of a coil spring 300 that can be twisted or bent, the coil spring 300 is in the width direction of the skateboard Both ends are fixedly installed on the front and rear plates 100 so as to be spaced apart from each other by a predetermined interval.

Therefore, it is possible to easily change the direction simply by rotating the front plate 100 in the advancing direction during the change of direction, it is returned to its original state by removing the force applied to the front plate (100). At this time, at both ends of the coil spring 300 is provided with a shaft diameter portion 310 is reduced at a predetermined interval to reduce the diameter, respectively, when fixed to the front / rear plates (100,200) by a fixing bracket 30 to be described later, It is configured to be firmly fixed without being separated in the axial direction in the rear plate (100,200).

In addition, the protective tube 500 of the flexible rubber or synthetic resin material is fitted to the circumferential portion of the coil spring 300, so that the appearance may be neat.

And both ends of the coil spring 300 is firmly fixed to the front / rear plates (100, 200) by a fixing bracket (30). The fixing bracket 30 extends horizontally in the opposite direction from each other at an end of the locking portion 32 having a cross-shaped U-shape opening, and a flange portion 34 having a coupling hole at the center thereof. Is made of. Therefore, in the state in which the engaging portion 32 of the fixing bracket 30 is fitted to the shaft diameter portion 310 of the coil spring 300, a fixture such as a screw is used to pass through the through hole of the flange portion 34. It is fixed to the rear plate (100,200).

Accordingly, the coil spring 300 is fixed to the front and rear plates 100 and 200 in a state where the fixing spring 30 is locked, thereby preventing the coil spring 30 from being separated in the axial direction. have.

According to this configuration, the skateboard is divided into front and rear plates (100,200), and the front and rear plates (100,200) are connected to each other by the coil spring 300, so that the front and rear plates (100,200) Not only can it be twisted in the opposite direction but it can also be bent.

Therefore, the skateboard is driven while the user's feet are placed on the front / rear plates 100 and 200, respectively, and only the front plate 100 is rotated in the direction of travel when the direction is changed in one direction during driving. The direction is simply switched, and even when the direction is changed again to the other direction, only the front plate 100 can be simply rotated in the direction to proceed, so that the direction can be easily switched.

At this time, the front plate 100 is elastically restored by the coil spring 300 when the direction is changed in the other direction in the state of switching the direction by rotating the front plate 100 to one side, by this elastic restoring force By rotating the front plate 100 in the other direction with a relatively small force can be switched direction. In this case, when the front plate 100 is rotated while being inclined upward in the advancing direction, the front plate 100 can be quickly switched with little force.

In addition, if the user simply rotates the front plate 100 to the left and right in order to improve the driving force while driving, in particular, the driving force is improved by only rotating the front plate 100 while twisting.
