Abstract

PROBLEM TO BE SOLVED: To provide a bolt that does not easily loosen as it is even when screwing is stopped at any position during screwing and is optimal to a level adjuster used for a table, although a bolt has a mechanism in which it does not easily loosen by fastening and thus a double nut is used for fixing it during fastening, but fastening operation of the double nut is complicated. SOLUTION: In this bolt having a locking mechanism, a groove 3 is provided over the entire length of a screw part 2 of the strong bolt 1 made of steel or the like, a filler 4 having high elasticity and coefficient of friction such as rubber is inserted into the groove 3, the filler 4 has a diameter slightly larger than root diameter of the screw part 2 and contact with a screw thread 6 of a counter female screw 5.

2. Description of the Related Art Many conventional locking mechanisms have a devised nut side, which is inconvenient when a counterpart body is provided with a tapped hole. In many cases, a spring seat is used so as not to be loosened, but there is no effect unless tightened, and it is useless in a loosened state. Therefore, in many cases, the male screw side or the female screw side is made of a resin having a large friction coefficient, but this resin made has a drawback in that the strength is weak.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 and 2. A U-shaped groove (3) is provided over the entire length of a screw portion (2) of a steel bolt (1). A rubber filler (4) is inserted into the groove (3), and the filler (4) is slightly larger than the root diameter of the screw portion (2), and the thread (6) of the mating female screw (5) is formed. ).
The groove (3) also needs to have the shape shown in FIG. 3 so that the filler (4) does not fall off without the adhesive.
