That is, the bracket 274 is moved by the wire cable 276, and the bracket 274 moves the second sprocket 256, the large gear 254a, the small gear 254b, and the reverse rotation gear 272. ) May move in the axial direction along the second wheel 24 rotation axis 252.

In this case, the worm gear or the helical gear 282 of the shaft member 280 is separated from the large gear 254a and engaged with the reverse rotation gear 272.

Accordingly, the rotational force transmitted from the pedal 30 rotates the second sprocket 256 and the small gear 254b associated with it. In addition, as the small gear 254b rotates the reverse rotation gear 272 in the reverse direction, the reverse rotation force is transmitted through the shaft member 280.

As described above, the rotational force transmitted in the reverse direction rotates the main gear 222 and the driven gear 224, which are the rotation transmission body 220, in the reverse direction. Therefore, the main gear 222 and the driven gear 224 is rotated in engagement with the concave-convex portion 314 provided on the inner surface of the hula hoop 300 in the reverse direction of the hula hoop 300 guided by the guide portion 230. Let's go.

In addition, the power transmission unit 250 in the present embodiment has been described as being provided to the rotating shaft of the second wheel 24 of the bicycle 10, the installation structure of the power transmission unit 250 and the shaft member 280 and The connection structure of the hula hoop body 310 is not limited thereto.

For example, the power transmission unit 250 may be provided adjacent to the handle 12.

In addition, the shaft member 280 of the power transmission unit 250 may be connected in the lateral direction or the upper direction of the hula hoop 300, for this purpose, the cutout portion 312 of the hula hoop body 310 is a side or top surface Can be provided.

Therefore, the present embodiment can easily fit the hula hoop 300 by the user through this structure, it can provide ease of installation.

In addition, in this embodiment, the power transmission unit 250 has been described as the power is transmitted as the user rotates the pedal 30, but the motor driving unit (not shown) mounted on one side of the bicycle 10 It is also possible to be connected by rotation.

Therefore, the occupant can automatically rotate only the hula hoop 300 by using the rotational force of the motor driving unit in the saddle 28, thereby performing the hula hoop 300 without straining other joints or muscles. It is also possible. Therefore, the occupant may exercise the waist or the belly fat without worrying that the legs may worsen due to the increase in the leg muscles due to the exercise of the bicycle 10.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents. It will be clear to those who have knowledge.
