1. A locking device especially for use in locking disk brake of motor cycle comprising:

  • a body having a first side, a second side adjacent to said first side, and a slot of a length and substantially perpendicular to said first side;

    said body being divided by the slot into a first portion and a second portion having a width smaller than said first portion, said first portion having a tunnel parallel to said first side;

    a locking bolt disposed in said body such that said locking bolt can be caused by an external force to move from a first position to a second position so as to seal off an opening end of said slot of said body, said locking bolt having an outer diameter so dimensioned as to permit said locking bolt to pass through one of heat-radiating holes of a disk brake of a motor cycle, said length of said slot being sufficient to receive said disk brake;

    said locking bolt being disposed in a front segment of said tunnel, a locking apparatus being fastened in a rear segment of said tunnel;

    a locking apparatus housed in said body and provided with a lock core capable of remaining at a third position or a fourth position at such time when said locking apparatus is in an unlocking state or in a locking state, said lock core being at said third position at such time when said locking bolt is caused to move to remain at said first position, and further said lock core being at said fourth position at such time when said locking bolt is caused to move to remain at said second position;

    wherein said locking bolt is so disposed that the axis of said locking bolt is parallel to said first side; and

    wherein said lock core is coupled with said locking bolt in such a manner that the axes of said lock core and said locking bolt are parallel to each other,wherein said second portion is provided with a slanted through hole in communication with a locking hole;

    wherein dust deposited in said locking hole is forced out through said slanted through hole when said locking bolt is inserted into said locking hole.
