The other side of the second cable 12 is inserted into a guide tunnel 14a formed by a cover 14 attached to the front surface of the upper front part 2, and is slidable within this guide tunnel 14a. That is, the second cable 12 passes through the two holes 16 and 17 provided in the opening wall 15 of the guide tunnel 14a and enters the guide tunnel 14.
a, and is prevented from coming out of the guide tunnel 14a by two holes 16 and 17 in the opening wall l5. Near the other end of the guide tunnel 14a of the upper front portion 2, a hook l8 is rotatably provided with a pin 19. An arm 20 is provided on the hook 18 so that it can be operated by a user. A spring 2l is provided between the arm 20 and the inner wall surface of the cover l4, and urges the tip of the hook 18 against the inner wall surface of the cover l4.

An inclined surface 18a is formed at the tip of the hook 18. That is, when the second cable 12 slides and its end 12a passes between the slope 18a of the hook 18 and the inner wall surface of the cover 14, it is automatically latched by the bias of the spring 21. The end of the second cable 12 is U
It has a hard end 12a in the shape of a letter.

The base 8 in contact with the rear part 3 of the upper is connected to the rear part 3 of the upper.

The ends 81 and 82 of the foot 80 are rounded.
is the installation side of the first cable 10. When the upper is open, the foot 80 is in the groove 2 like the base 28.
2 and along the bottom surface of the groove 22. When locking, the operation is exactly the same as in the previous example, but the tightening lever 7
0 around the end 81 to tighten the second cable, and when the tightening lever 70 is returned in the direction of arrow F2 as shown in FIG. 2, the end 82 will tighten as shown in FIG. The difference is that it separates from the outer surface of the upper.

Note that the second cable 12 may be automatically hooked and fastened by other methods. The hook 18 may be elastically provided with a lock tongue-like member, such as a door latch, so that the hook 18 can be moved in and out. A hook may be provided at the end of the second cable 12. Also cables 10, 1
2 may form a single arm without forming a buckle, and the end of the cable 12 may be provided with a ring. Furthermore, it goes without saying that the present invention can also be applied to a device in which only the upper rear portion 3 is rotatable relative to the shell.

[Effects of the Invention] Since the ski boots according to the present invention are as described above, the closing and locking means of the upper of the boots has been improved so that the upper can be accurately closed and locked with one hand, and the upper can be fully closed when the foot is put on. This has the effect of allowing it to be opened.
