Then, the helical protrusion 10 of the stud bolt 9 and the locking pawl 15 of the locking piece 14 engage in an engagement relationship similar to a ratchet mechanism, whereby the locking portion 8 is locked to the stud bolt 9. Become.

As a result, the positioning and fixing of the P1'' actor to the steel plate body 4 can be accomplished at the same time.

Further, according to this example, when each locking portion 8 of the protector main body 1 is locked IF to a plurality of stud bolts 1-9, between the stud bolt 9 and the locking portion 8 in the longitudinal direction of the protector main body 1. Even if there is a slight positional deviation, the locking can be achieved, so even if the pitch between the axes 8 of the stud bolts 9 is slightly off from the specified value, the big error can be absorbed, Can be installed easily.

In addition, when it is desired to remove the protector that has been attached, the release piece 16 on the upper edge of the locking pawl 15 can be pressed in the opposite direction with the tip of the operator's finger or a release tool. The protector can be easily removed from the steel plate body 4 by bending and opening 14 and disengaging the locking pawl 15 from the helical protrusion 10 of the stud bolt 9.
