Therefore, as mentioned above, after the wheel 25 protrudes out of the sole B, the roller blade can be enjoyed in that state.

Next, the storage of the wheel assembly 20 after use as a roller blade proceeds in the reverse order of the above-described drawing, and rotates the body 31 of the operating lever 30 upward by 180 ° to return to the initial position. Then, the withdrawal-side fixing pin 35 on the upper side moves downward, and the storage-side fixing pin 34 on the lower side moves upward and the receiving wire 41 is pulled so that the front and rear wheels 26 ( 27 are folded and received inside the housing 10. Therefore, it can also function as a normal shoe without a roller blade at the bottom of the sole B. FIG.

On the other hand, Fig. 11 shows another embodiment of the above-described operating lever 30 '. This forms assembly grooves 31a 'and 31b' at 180 ° intervals on the outer circumferential surface of the discoid body 31 'having the handle 32' and ratchet wheels 36 'and 37' thereon. An accommodating side and an extracting side spool 34 'and 35' having a rotatable side are rotatably mounted to fix one end of the accommodating and extracting wires 41 and 42 of the wheel drive wire 40. At this time, the teeth of each ratchet wheel (36 ', 37') is configured to face in the opposite direction for smooth operation of the wheel drive wire (40). In addition, the body 31 'is provided with ratchet 38' (39 ') which elastically latches and positions the teeth of each ratchet wheel 36' (37 '), and each spool 34 (35) is provided. The tool insertion grooves 34a 'and 35a' into which tools such as a driver can be inserted are formed.

In this embodiment, the wheel drive wire 40 is stretched due to the frequent use of the roller blades, so that a tool such as a driver may be used to store or pull out the spool 34 'and 35' of the operating lever 30 '. Insert the tool insertion grooves 34a 'and 35a' and turn them in the winding direction so that the wheel drive wire 40 is wound around the spools 34 'and 35' as much as the wheel drive wire 40 is stretched. It can be adjusted tightly.

As described above, according to the present invention, the roller blade is normally stored in the sole of the shoe and worn like a normal shoe, and the roller blade can be easily taken out and used only when necessary. And roller blade functions. Therefore, there is no need to separately provide shoes and roller blades as in the prior art, and in particular, there is no need to carry the roller blades separately, and there is no need to wear shoes and roller blades alternately depending on the location conditions.

Therefore, the present invention has a very excellent effect of greatly improving the functionality and economy and convenience of shoes.
