<P>PROBLEM TO BE SOLVED: To provide a locking bolt which allows a locking operation to be performed only from the front side of a to-be-fixed member even when the space at the rear side of the to-be-fixed member is narrow and small, while, even in the case of a necessity to frequently separate the to-be-fixed member, it allows for the easy separation thereof, and which is capable of being re-used. <P>SOLUTION: The locking bolt is composed of: a bolt 2 in which a through hole 22b is formed from a head part 2 down to the tip end; a nut 3 in which a first female screw 31b into which the male screw 22a of the bolt is screwed in is formed, a bottom plate part 32 is formed at the tip end side, and a second female screw 32a whose pitch is different from that of the first female screw is formed at the central part of the bottom plate; and a small bolt 1 which is inserted into the through hole from the head part of the bolt, and whose tip end is screwed into the second female screw. The bolt is inserted through the front surface side of the to-be-fixed member and screwed into the first female screw of the nut formed on the rear surface side thereof for tightening, and then the small bolt is screwed into the second female screw formed on the bottom plate part of the nut to be finally locked. <P>COPYRIGHT: (C)2012,JPO&INPIT |
