【Example】

 Next, an embodiment of the protector according to the present invention will be described.

FIG. 1 shows a protector 27 according to the embodiment. In the figure, the protector 27 is composed of a protector body 29, a lid body 43 for closing the protector body 29, and a locking means 45 for locking the lid body 43 to the protector body 29.

From both sides of the bottom portion 31 of the protector body 29, bellows-shaped and expandable / contractible side walls 33 are integrally formed with the bottom portion 31. These side walls 33 are formed with a predetermined gap 35 so that the side walls 33 can easily expand and contract at the bent portion of the protector body 29. The upper ends of the side walls 33 are connected to each other by the upper connecting body 34. Corresponding to the gap 35 between the side walls 33, a locking portion 37 is integrally projected from the side portion of the bottom portion 31.

The locking portion 37 has a cylindrical locking frame portion 39 that projects laterally from the bottom portion 31, and a side wall 33 that projects from the inner wall of the locking frame 39 toward the bottom portion 31. On the other hand, the locking claw 41 has an inclined surface formed on the opposite side.

On the other hand, the lid 43 is formed in a shape following the shape of the protector main body 29 and has a flat plate-shaped wire pressing portion 47 having a width larger than the width between the side walls 33. It is composed of a side wall portion 48 that is bent in a vertical direction, and a plurality of locking arms 49 that project from the side wall portion 48 at a predetermined interval corresponding to the locking portion 37. These locking arms 49 are formed with a plurality of stages of locking projections 51. When the locking arms 49 are inserted into the locking frame 39, the locking claws 41 have a plurality of levels of engagement. The locking arm 49 is locked to one of the stop projections 51 so that the locking arm 49 is selectively locked at a plurality of positions. Further, a pair of positioning protrusions 43a is provided between the locking arms 49 in the same direction as the locking arms 49.
