The pipe is connected to each other in a direction intersecting the axial direction and has a main body and a lid that cover the end of the pipe, and at least one of the main body and the lid is provided with a protector-side locking portion. When the main body part and the lid part are connected, the protector-side locking part is fitted in a concave-convex manner from a direction intersecting the axial direction, and the protector is displaced in the circumferential direction and the axial direction of the pipe. A restricting portion on the pipe side for regulating is provided.

According to this configuration, the protector has the main body and the lid, and the electric wire can be routed along the main body, and the lid can be connected to the main body in that state, so the electric wire is passed toward the inside of the protector. It does not require work, and has excellent workability in assembly. When the lid is connected to the main body, the protector-side locking part engages with the pipe-side locking part in a concavo-convex manner in a direction intersecting the axial direction, and the protector is displaced in the circumferential and axial directions with respect to the pipe. Since it is held in a regulated state, it is not necessary to provide a specially complicated connecting structure to the pipe and the protector as the positional deviation regulating means, and the protector can be reliably coupled to the pipe.

[2] The pipe is preferably an extruded product made of resin. For example, the pipe-side locking portion may be formed from the pipe of the extruded body without any trouble, as long as it has a form in which the protector-side locking portion is fitted in the recess and projection.

As shown in FIG. 9, the main body side lock portion 36 has a substantially L-shaped form in a front view that protrudes substantially horizontally from the outer surface of the side wall 34 and then stands substantially vertically. The connecting portion (base end portion) can be flexibly deformed inward and outward with the fulcrum as a fulcrum. The main body side lock portion 36 has a lock hole 37 which penetrates in the vertical direction and whose lower portion is opened laterally.

As shown in FIG. 9 and FIG. 10, on the inner peripheral surface (upper surface) of the main body side wrap portion 33, the main body side as a protector side locking portion is provided at a position at the center of the left and right which is the lowermost portion and near the end edges. The protrusion 38 is provided so as to project. The main body side protrusion 38 has a flat cross-section with a circular cross section, and the upper surface (the front end surface in the protruding direction) is formed in an arc shape having the same curvature as the inner surface of the lower half of the main body side wrap portion 33. The main body side protrusion 38 can be fitted into the hole 21 of the pipe 20 with substantially no space. The protrusion size of the main body side protrusion 38 is made slightly smaller than the thickness of the peripheral wall of the pipe 20.

The lid 32 has a horizontal plate-shaped lid-side wrap 39 capable of covering the lap region 22 of the pipe 20 from above. The lid-side wrap portion 39 has a substantially rectangular shape in a plan view and has a size capable of closing the upper surface opening of the main body-side wrap portion 33. As shown in FIGS. 7 and 8, a pair of side edge portions 41 protruding downward are provided on both left and right sides of the lid side wrap portion 39 over the entire length in the axial direction. As shown in FIG. 6, the both side edge portions 41 are arranged so as to cover the upper ends of the both side walls 34 of the main body side wrap portion 33 from both sides, and the lid side wrap portion 39 is left and right with respect to the main body side wrap portion 33. It plays a role of restricting displacement in the direction.

Lid-side lock portions 42, which are paired with each other in the axial direction, are provided at the lower ends of the both side edge portions 41 so as to project. The lid-side lock portion 42 has a rectangular plate shape, and a claw-shaped lock protrusion 43 is provided on the outer surface so as to project. As shown in FIG. 2, the lock protrusion 43 can be fitted into the lock hole 37 of the main body side lock portion 36.

As shown in FIGS. 7 and 8, on the lower surface of the lid-side wrap portion 39, a lid-side projection portion 44 serving as a protector-side locking portion is provided so as to project at a position in the center of the left and right and near the end edge. There is. Like the main body side protrusion 38, the lid side protrusion 44 is formed in a flat trapezoidal shape having a circular cross section. As shown in FIG. 5, the lower surface of the lid-side protrusion 44 has an arc shape symmetrical to the upper surface of the main-body-side protrusion 38. Further, the projecting dimension of the lid-side projecting portion 44 is made slightly smaller than the thickness of the peripheral wall of the pipe 20, similarly to the main body-side projecting portion 38.

On the lower surface of the lid-side wrap portion 39, a lid-side restriction portion 45 is provided so as to project closer to the edge than the lid-side protrusion 44. The lid-side restricting portion 45 has a plate-like shape that extends in the left-right direction and has a divided central portion, and has a lower surface curved with the same curvature as the lower surface of the lid-side protruding portion 44.

Next, the assembly structure of the wire protection member 10 of the first embodiment will be described. At the time of assembly, the plurality of electric wires 90 are inserted into the pipe 20 and are routed along the inner surface of the main body portion 31, and the main body side wrap portion 33 is externally fitted to the lap region 22 of the pipe 20 before and after that. It Then, the lower half portion of the pipe 20 is arranged along the inner surface of the lower half portion of the main body side wrap portion 33, and the main body side protrusion 38 of the main body side wrap portion 33 is in the hole 21 on the lower half portion side of the pipe 20. It is inserted in a fitted state from below (see FIGS. 4 and 5). Since the main body side protrusion 38 is inserted into the hole 21 and can come into contact with the hole edge of the hole 21, the displacement of the main body 31 with respect to the pipe 20 in the axial direction and the circumferential direction is restricted. At this time, the tip of the main body side protrusion 38 does not reach the inside of the pipe 20 and does not come into contact with each electric wire 90. Further, the side surface portion of the main body side restricting portion 35 is arranged so as to be able to contact the upper half portion of the pipe 20 from both the left and right sides, and the main body side wrap portion 33 is in a state in which it is restricted from coming out of the pipe 20.

Then, the lid 32 is put on the body 31 from above. As the upper surface opening of the main body 31 is closed by the lid 32, the lock protrusions 43 of the respective lid-side locks 42 are elastically fitted and locked in the corresponding lock holes 37 of the main-body-side lock 36, and the lids are closed. The part 32 is integrally held by the body part 31 (see FIG. 2).

Further, when the lid portion 32 is integrally held by the main body portion 31, the lid-side projection portion 44 of the lid-side wrap portion 39 is inserted into the hole 21 on the upper half portion side of the pipe 20 from above to fit the lid portion. The displacement of 32 in the axial direction and the lateral direction with respect to the pipe 20 is restricted (see FIG. 5 ). Further, the lower surface portion of the lid-side restricting portion 45 is arranged so as to be able to contact along the outer peripheral surface of the upper half portion of the pipe 20.

In this way, the protector 30 is formed by connecting the main body portion 31 and the lid portion 32 in the separation-restricted state. Further, when the body portion 31 and the lid portion 32 are connected, the lap region 22 of the pipe 20 is sandwiched between the body portion 31 and the lid portion 32, and the body side protrusion 38 and the lid side protrusion 44 respectively correspond to the corresponding holes 21. The protector 30 is fixed to the pipe 20 in a positioned state by being fitted and inserted in the vertical direction.

After that, the electric wire protection member 10 is arranged along the bottom surface of the floor of the vehicle, and is attached to the vehicle via a mounting portion (not shown). At this time, the flat upper surface of the lid portion 32 is disposed substantially parallel to the vehicle along the lower floor surface of the vehicle. Therefore, the protector 30 can be installed on the underside of the floor of the vehicle in a stable posture, and a large wire insertion space inside the protector 30 can be secured.

As described above, according to the first embodiment, the protector 30 has the main body portion 31 and the lid portion 32, the electric wires 90 are routed along the main body portion 31, and the lid portion 32 is attached to the main body portion 31 in that state. Since they can be connected, it is not necessary to pass each electric wire 90 toward the inside of the protector 30, and the workability of assembling is excellent.

Further, when the lid portion 32 is connected to the main body portion 31, the lap region 22 of the pipe 20 is sandwiched between the main body portion 31 and the lid portion 32, and the main body side projection portion 38 and the lid side projection portion 38 serving as protector side locking portions. It is possible to prevent the protector 30 from being displaced in the circumferential direction and the axial direction with respect to the pipe 20 by the concave-convex fitting of the portion 44 in the hole 21 as the corresponding pipe-side locking portion from the vertical direction (the direction intersecting the axial direction). Since it is held in a regulated state, the protector 30 can be reliably coupled to the pipe 20 without providing a specially complicated coupling structure for the pipe 20 and the protector 30 as the positional deviation regulating means.

Further, since the pipe side locking portion is merely provided as the hole 21, the extrusion molded body of the pipe 20 can be formed without any trouble.
Further, both the main body 31 and the lid 32 are provided with the main body-side protrusion 38 and the lid-side protrusion 44 serving as protector-side locking portions, so that the protector 30 can be reliably and stably attached to the pipe 20. Be connected.

Further, a body-side lock portion 36 and a lid for holding the body portion 31 and the lid portion 32 in a connected state are provided at both axial ends of the body-side wrap portion 33 and the lid-side wrap portion 39 which overlap the lap region 22 of the pipe 20. Since the side lock portion 42 is installed, even if foreign matter or the like interferes with the main body side wrap portion 33 and the lid side wrap portion 39 to generate a large stress, the stress causes the main body side lock portion 36 and the lid side lock portion. 42 can withstand, and the protector 30 can be more effectively prevented from being displaced with respect to the pipe 20.

Further, the pipe side locking portions are holes 21 and 21B penetrating the peripheral wall of the pipe 20, the holes 21 and 21B are provided at both axial ends of the pipe 20, and the holes 21 and 21B provided at both axial end portions thereof. One of the holes 21B has a long hole shape that is long in the axial direction, and has a shape in which the main body side protrusion 38 and the lid side protrusion 44 can be loosely fitted in the axial direction. When the protectors 30 are connected to both ends, even if an axial assembly error occurs between the protector 30 and the pipe 20, the main body side protrusion 38 and the lid side protrusion 44 are formed in the one hole 21B. It is fitted with play in the axial direction (see Figure 4). Therefore, the assembling error between the protector 30 and the pipe 20 is absorbed, and the main body side protrusion 38 and the lid side protrusion 44 can be reliably fitted into the holes 21 and 21B, respectively.
