Next, an embodiment of the holder of the present invention will be described with reference to FIGS.
In the drawings, members (components) having the same or corresponding functions are denoted by the same reference numerals and description thereof is omitted as appropriate.

As shown in FIG. 7, the holder 10 according to the present embodiment includes, for example, a held member 18 such as a PC coat tube formed by extrusion coating polypropylene (PP) resin such as a fuel pipe or a brake tube of a vehicle, a sensor harness, or the like. This is applied to a portion held by the covered cable 60.

As shown in FIGS. 1 and 2, the holder 10 of the present embodiment is made of a material such as a resin material having elasticity, and the held member 12 having a long shape such as a cylindrical shape or a columnar shape is provided. A holding unit 14 for holding is provided. Moreover, the holding part 14 has an opening 16 for inserting the held member 12 in a direction (arrow B direction in FIG. 1) intersecting with the longitudinal direction (arrow A direction in FIG. 1 or the direction opposite to the arrow A). The opening 16 is formed along the longitudinal direction of the held member 12.

As shown in FIG. 3, the holding portion 14 has a U-shape when viewed from the longitudinal direction of the held member 12, and the holding portions 14 are arranged in parallel across the opening 16 and face each other. A pair of opposing wall portions 20 and 22 (inner peripheral opposing surfaces) as inner peripheral opposing surfaces, and an arcuate bottom wall portion 24 that connects one end (lower end in FIG. 3) of these

opposing wall portions

20 and 22; It has.

As shown in FIGS. 4 and 5, inclined ribs 30 are formed on one of the opposing wall portions 20 so as to protrude. The inclined rib 30 has an angle θ1 toward the longitudinal direction of the held member 12 (the direction of arrow A in FIG. 5) with respect to the vertical insertion direction of the held member 12 from the opening 16 (the direction of arrow B in FIG. 5). Inclined. The inclination angle θ1 is set to 30 degrees, for example.

As shown in FIG. 5, the tip end 30A of the inclined rib 30 has an acute angle, and as an example, in this embodiment, the cut surface shape intersecting with the longitudinal direction of the inclined rib 30 is a triangle.

As shown in FIG. 4, inclined ribs 32 project from the other opposing wall portion 22 of the holding portion 14 at a position facing the inclined rib 30. The inclined rib 32 is formed at the same inclination angle θ 1 as the inclined rib 30, and the tip 32 A has the same acute angle as the inclined rib 30. In addition, the inclined rib 30 and the inclined rib 32 extend to the bottom wall portion 24, and the inclined rib 30 and the inclined rib 32 are connected to each other at the bottom wall portion 24.

Therefore, when the held member 12 is inserted from the opening 16 into the holding portion 14 in the direction of arrow B in FIG. 5, the insertion force B is perpendicular (compressed) to the shearing direction force F1 on the

inclined ribs

30 and 32. A directional force F2 is generated. For this reason, holding member 12 is held by holding member 12 being inserted into holding portion 14 while inclined

ribs

30 and 32 having sharp edges 30A and 32A bite into the outer peripheral portion of held member 12. The insertion force into the portion 14 can be reduced.

For this reason, when the held member 12 held by the holding portion 14 tries to rotate in a direction intersecting the longitudinal direction (direction of arrow R in FIG. 7), one of the inclined rib 30 and the inclined rib 32 draws a spiral. Trying to rotate, but the other receives rotation on the side. For this reason, the load in the rotation direction of the held member 12 held by the holding portion 14 is increased, and rotation is prevented.

Therefore, the inclined rib 30 and the inclined rib 32 prevent the held member 12 held by the holding portion 14 from moving in the longitudinal direction (the direction of arrow A in FIG. 1 or the direction opposite to the arrow A). It is possible to prevent rotation in the direction intersecting the longitudinal direction (the direction of arrow R in FIG. 7).

As shown in FIG. 1, the holder 10 includes a lid 40 that closes the opening 16 of the holder 14. The lid 40 is connected to the one opposing wall 20 side of the holding unit 14 by a hinge 42, and the lid 40 is in the open position shown in FIGS. 2 and the closed position shown in FIG.

When 44 and 46 slide, it bends in the direction once separated. Further, when the locking piece 44 is pressed to the holding portion 14 side, the locking

pieces

44 and 46 get over each other, so that the locking

pieces

44 and 46 are restored to their original state by their own elasticity. For this reason, as shown in FIG. 7, the engaging

pieces

44 and 46 are engaged with each other so that the opening portion 16 of the holding portion 14 is closed with the lid portion 40.

It should be noted that a plurality of convex portions 48 are formed on the outer surface of the one opposing wall portion 20 in the holding portion 14, and a plurality of notches 49 are formed in the lid portion 40. Further, when the lid portion 40 is set to the closed position, the convex portion 48 of the holding portion 14 enters the notch 49 of the lid portion 40. For this reason, when a force in a direction away from the holding portion 14 (the direction of arrow D in FIG. 7) acts on the lid portion 40 in the closed position, the convex portion 48 abuts on the peripheral portion of the notch 49, thereby The part 42 can be prevented from being damaged.

As shown in FIG. 7, the portion of the lid 40 that closes the central portion in the width direction of the opening 16 is an arcuate curved surface 40 A along the outer periphery of the held member 12. On the curved surface 40A, ribs 50 project from the circumferential direction.

As shown in FIG. 6, the rib 50 has a sharp tip 50A, and as an example, in the present embodiment, the cut surface shape intersecting with the longitudinal direction of the rib 50 is a triangle.
