6 is an exploded perspective view showing the configuration of a second pumping member in a shoe having a forced ventilation structure proposed in another preferred embodiment of the present invention.

Referring to the embodiment of Figure 6, the pumping member of the present embodiment is installed in the arch portion of the shoe (part corresponding to the inner arch of the foot), the worm 38 and the corresponding worm wheel 37 is installed, It has a structure which rotates the fin 38 externally and raises and lowers the support body 33.

That is, a worm wheel 37 is formed below the support 33 supporting the spring 34, and a worm 38 is formed to be engaged with the wheel. The worm 38 is exposed to the outside as shown in the head so that it can rotate outside of the body. The worm wheel 37 has an insertion groove into which the support is inserted, and a fastening screw portion 39 is formed in the insertion groove to be screwed with the thread of the outer surface of the support, and the outer surface of the worm wheel is fastened with the worm. Threads in the vertical direction are formed.

Due to this configuration, when the user (wearer of the present invention) rotates the wheel in one direction, when the worm wheel 37 is rotated, the support 33 inserted into the inner insertion groove of the worm wheel according to the fastening screw portion 39 As it rotates along, it rises or falls.

On the other hand, as shown, in the present embodiment, the height adjustment opening 35 has a bolt shape in which the groove 35a is formed in the lower portion, not the angular bolt shape, the fastener 45 in the lower portion of the groove 35a. It is configured to be inserted and fixed to the projection jaw (45b) of the).
