The pawl 32 is slidably coupled to the support base 21 in a forward and backward direction so as to be positioned in front of the winding drum 10 so that a rear end of the pawl 32 is engaged with the ratchet 31.

The elastic member 33 is connected to the rear end of the pawl 32 and uses a coil spring to press the pawl 32 backward.

At this time, the pawl 32 is configured to be fixed so that its distal end portion is resiliently engaged with the ratchet 31 so that the connection member D wound on the circumferential surface of the winding drum 10 is not rotated in the unwinding direction.

That is, the ratchet 31 is formed in a wedge shape inclined clockwise. When the winding drum 10 is rotated in the clockwise direction around the connecting member D, the pawl 32 is elastically retracted So that the winding drum 10 is freely rotated and the winding drum 10 is not rotated in the counterclockwise direction in which the connecting member D is disengaged.

Therefore, when the user presses the upper end of the lifting shaft 23 downward with the heel, the nut member 25 rotates counterclockwise. At this time, the nut member 25 is rotated by the one- And the winding drum 10 are mutually fixed and the winding drum 10 is rotated together with the nut member 25 to wind the connecting member D by pulling it.

On the other hand, when the user lifts the heel, the lifting shaft 23 is pushed upward by the elastic member 24 and the nut member 25 is rotated in the clockwise direction. At this time, The fixing of the nut member 25 and the winding drum 10 is released and the winding drum 10 is fixed by the fixing means 30 so that the winding drum 10 is not rotated, (25) is idling.

Therefore, when the user repeatedly depresses the lifting shaft 23 with the heel, the lifting shaft 23 is lifted and lowered so that the winding drum 10 is rotated in the counterclockwise direction, The shoe strap C is pulled while being wound around the circumferential surface of the shoe 10 so that the shoe is tightened.

5, the fixing unit 40 has a front end fixed to the sole A and a rear end configured as a wire connected to the pawl 32 of the fixing unit 30. The outsole When the toe portion of the shoe is bent upwardly, the pulling wire pulls the pawl 32 to pull the pawl 32 and the ratchet 31 out of engagement with each other, .

The rear end of the releasing means is connected to the pawl 32 and the front end of the releasing means extends forward along the space portion 2 formed in the inside of the sole A, As shown in FIG.

Therefore, when the tip of the sole A is bent upward toward the center of the toe portion, the distance between the front portion of the shoe and the pawl 32 is extended, so that the releasing means 40 is pulled toward the front of the shoe , Whereby the pawl 32 is pulled forward and the engagement between the pawl 32 and the ratchet 31 is released.

At this time, when the user generally walks in the state of wearing the shoe, the unlocking means 40 is rotated at a slightly larger angle with respect to the angle at which the front portion of the shoe is bent, that is, 40 are configured to pull the pawl 32.

A separate insole 3 is provided at the upper part of the sole A so that the tightening mechanism E is obscured.

A cushioning member (50) is provided in the recess (1).
