However, even if the bolt 3 is not loosened, the bolt 3 can be pulled (impactly) by pulling the handle 15 so that each bolt 3 is pulled through the through hole 13 or the notch hole 11. It is possible to detach from. Thus, since the protector 1 can be removed without removing the bolt 3, maintenance performance and disassembly (disassembly) workability are improved.

  In the above-described embodiment, the through-hole 13 that is a fixed portion near the center of gravity and the brackets 7 to 10 on the peripheral wall side are provided, but either one, that is, the brackets 7 to 10 on the peripheral wall side or the notch 14 near the center of gravity. It is also effective to provide only the attached through hole 13.

  In these cases, it is possible to provide two through-holes 13 with notches instead of one and provide a pulling handle 15 for each through-hole. The shape of the handle 15 is not limited to the U shape, and may be an arc shape or a belt shape. Further, the fixed portion near the center of gravity is limited to the conventional through-hole 13 having no notch (the bolt 3 needs to be removed), and brackets 7 to 10 with the notch 11 are provided on the peripheral wall side (the bolt 3 is not required to be removed). It is also possible. Each bolt 3 may vary in size between the brackets 7 to 10 and the through hole 13.

  In the above-described embodiment, the protector 1 for constantly supplying power is used as the resin component. Instead of this, as a resin component, a cage-shaped resin protector for accommodating and protecting the wire harness in the vehicle body or the like, Use power supply resin protectors that are placed on dynamic doors, slide seats, etc. to absorb the extra length of the wire harness, resin electrical junction boxes or resin junction blocks that are fixed to the vehicle body, etc. Needless to say, each resin component can be easily removed without removing the bolts. Also in these resin parts, it is possible to use only the outer peripheral side cutout hole 11 or only the through hole 13 with the cutout 14 on the inner side.

  Further, in each resin part, the pull handle 15 is abolished, and the bolt 3 is removed from the notch hole 11 and the notched through hole 13 while the resin part is peeled off with a tool such as a flat-blade screwdriver or a tire wrench. It is also possible to disengage. It is also possible to provide a hole or the like for putting a finger or the like and pulling it instead of the handle 15.

  Moreover, in the said embodiment, although the notch 14 was formed in the shape of a pointed mountain (notch), it is also effective to provide several slits radially as a notch, or to provide the cut | interval without a gap radially. It is. It is also possible to provide the bolt 3 on the mounting side in advance as an implantable type, insert the bolt into the notch hole 11 or the through hole 13, and tighten it with a nut (not shown) on the protector side.
