Furthermore, the protruding portion 130 is formed to protrude toward the holding space portion 113, so that at least a part of the holding space portion 113 is formed into a pair of divided holding space portions 113 </ b> A and 113 </ b> B in the stacking direction Z. This is the part to be divided (area division). Here, the holding space 113 is entirely divided into a pair of divided holding spaces 113A and 113B. The pair of divided holding space portions 113A and 113B are space portions constituting the holding space portion 113, and can hold the end portion of the corrugated tube C, respectively. In other words, the holding space portion 113 is divided into the divided holding space portions 113A and 113B by the protrusions 130, so that the corrugated tubes C are stacked and held in multiple steps (here, two steps) along the stacking direction Z. A holding space is formed. Here, the divided holding space portion 113 </ b> A constitutes a space portion that is located on the bottom 20 c side with respect to the projecting portion 130 in the stacking direction Z. On the other hand, the divided holding space portion 113 </ b> B constitutes a space portion that is located on the opposite side of the projecting portion 130 from the bottom portion 20 c side, that is, on the holding portion cover portion 112 side.

The shape is formed. More specifically, each protrusion 130 is formed in a substantially isosceles trapezoidal shape when viewed along the axial direction X (see FIG. 3).

  Next, the operation when the protector 1 is assembled will be described with reference to FIGS. 7, 8, 9, 10, and 11.

  In the protector 1 configured as described above, the base member 20 and the cover member 30 are not assembled, and the routing member W, the corrugated tube C, and the insertion space portion 40 in the base member 20 are opened. And assembled with each other. In the protector 1, as illustrated in FIG. 7, the end portion of the corrugated tube C into which the routing material W is inserted is inserted into the holding space portion 113 along the stacking direction Z. In this case, the corrugated tube C is inserted into the holding space 113 in such a positional relationship that the extending direction is along the axial direction X. In this case, first, the first-stage corrugated tube C is pushed into the divided holding space portion 113 </ b> A of the holding space portion 113. At this time, the protector 1 is further pushed into the divided holding space 113 </ b> A from the state in which the first-stage corrugated tube C is pressed along the stacking direction Z and is in contact with each protrusion 130. Thereby, as shown in FIG. 8, the protector 1 causes the end portion of the corrugated tube C to spread the flexible arm portion 121 of the flexible portion 120 outward in the width direction Y via the protrusions 130. The protrusions 130 are elastically deformed while being bent, and the projections 130 are retracted from the holding space 113 side, and the end portions of the corrugated tubes C get over the projections 130. As a result, as shown in FIG. 9, the protector 1 is housed and held in the one-side divided holding space 113 </ b> A with the end portions of the first-stage corrugated tube C sandwiching the protrusions 130. The flexible arm portion 121 of the flexible portion 120 is elastically returned to the original position, and returned to the position where each protrusion 130 protrudes toward the holding space portion 113.

  Next, as illustrated in FIG. 9, in the protector 1, the end portion of another corrugated tube C into which the routing material W is inserted is inserted into the holding space portion 113 along the stacking direction Z. Also in this case, the corrugated tube C is inserted into the holding space 113 in such a positional relationship that the extending direction is along the axial direction X. In this case, the second-stage corrugated tube C is pushed into the divided holding space portion 113B of the holding space portion 113. At this time, as shown in FIG. 10, the protector 1 divides the other corrugated tube C across the protrusion 130 at a position where the corrugated tube C of the second stage contacts the protrusion 130 and does not get over the protrusion 130. It is stored and held in the holding space 113B.

  Then, as shown in FIG. 11, the protector 1 has the cover member 30 locked to the base member 20 via the locking mechanisms 50 and assembled to each other and held in the closed position. In this state, the protector 1 is configured so that the end portion of the corrugated tube C is in the holding space portion 113 (divided holding space portions 113A and 113B) of the holding portion 110, and the meshing portion 114 (base portion side meshing portion 114a, cover portion side meshing). In a state in which dropping is restricted by the portion 114 b), they are stacked and held along the stacking direction Z. And the protector 1 will be in the state by which the routing material W exposed from the edge part of each corrugated tube C was penetrated in the main-body part insertion space part 13 of the main-body part 10, and was wired.

  Further, in the state shown in FIG. 11, the protector 1 is configured such that, in each locking mechanism 50, each locking projection 112 a is inserted into each locking hole 111 b, and each locking claw 112 b corresponds to each locking piece 111 a. It is in a state of being locked to the end surface on the bottom 20c side in the stacking direction Z. In this state, the holding portion cover portion 112 of the cover member 30 is positioned on the distal end portion side of the flexible arm portion 121 with respect to the stacking direction Z, partitions the holding space portion 113 together with the holding portion base portion 111, and Each locking protrusion 112a inserted into the stop hole portion 111b comes into contact with the distal end portion of the flexible arm portion 121. As a result, the holding portion cover portion 112 restricts the locking protrusions 112a from falling to the outside in the width direction Y of the flexible arm portion 121 (the side opposite to the holding space portion 113). That is, in this case, each locking projection 112a constitutes a locking mechanism 50 that locks the holding portion base 111 (base member 20) and the holding portion cover 112 (cover member 30), and a flexible arm. It is also used as a fall regulation unit that regulates the fall of the part 121.

  In the protector 1, the wire harness WH, and the holding mechanism 100 described above, the holding space portion 113 in the holding portion 110 is divided and held in a pair by the protruding portion 130 that protrudes from the flexible portion 120 toward the holding space portion 113. The space portions 113A and 113B are divided and configured. The protector 1, the wire harness WH, and the holding mechanism 100 hold the corrugated tubes C stacked on the holding space 113 by holding the corrugated tubes C with respect to the divided holding spaces 113A and 113B. can do. At this time, the protector 1, the wire harness WH, and the holding mechanism 100 are arranged such that the corrugated tube C is inserted into the holding space portion 113 along the stacking direction Z and the protruding portion is in contact with the protruding portion 130 while bending the flexible portion 120. The vehicle passes over 130 and is stored and held in the divided holding space 113A on one side with the protrusion 130 interposed therebetween. Thereafter, the protector 1, the wire harness WH, and the holding mechanism 100 are further positioned such that another corrugated tube C is inserted into the holding space portion 113 along the stacking direction Z and abuts the protruding portion 130 and does not get over the protruding portion 130. Thus, the protrusion 130 is held and held in the other divided holding space 113B. In this state, the protector 1, the wire harness WH, and the holding mechanism 100 are arranged in the corrugated tube C along the stacking direction Z with the protruding portion 130 as a partition portion on one side and the other side of the pair of split holding space portions 113A and 113B. Can be laminated and held. In this case, the protector 1, the wire harness WH, and the holding mechanism 100 are configured such that the projecting portion 130 that functions as a partitioning portion is interposed between the pair of corrugated tubes C and functions as a load receiving portion between them. It can suppress that the load of the other corrugated tube C acts on the corrugated tube C, and can suppress that each corrugated tube C is crushed. Thereby, the protector 1, the wire harness WH, and the holding mechanism 100 can be laminated and held on the holding unit 110 in a state where the appropriate outer shape of each corrugated tube C is maintained, and a stable holding force can be ensured.

Therefore, it can suppress more reliably that each corrugated tube C is crushed, and can hold corrugated tube C more appropriately.

  Further, in the protector 1, the wire harness WH, and the holding mechanism 100 described above, the protrusion 130 is formed in a tapered shape toward the holding space 113, so that the corrugated tube C is divided into the holding space 113A. The flexible portion 120 can be easily bent through the protrusion 130 when pushed. Furthermore, the protector 1, the wire harness WH, and the holding mechanism 100 are formed so that the protruding portion 130 is tapered toward the holding space portion 113, so that the protruding portion 130 is interposed between the pair of corrugated tubes C. It can be set as the structure which is easy to receive a load by interposing. As a result, the protector 1, the wire harness WH, and the holding mechanism 100 can improve the workability at the time of assembly and improve the production efficiency, and more reliably suppress the collapse of each corrugated tube C. The corrugated tube C can be held more appropriately.

  Further, the protector 1, the wire harness WH, and the holding mechanism 100 described above are configured so that the flexible portion 120 includes the flexible arm portion 121 that is supported by the holding portion 110 in a cantilevered manner. Since the part 120 can be configured to be easily bent with a smaller force, the workability at the time of assembly can be further improved, and the production efficiency can be further improved.

  Further, in the protector 1, the wire harness WH, and the holding mechanism 100 described above, the holding portion 110 includes the holding portion base portion 111 and the holding portion cover portion 112, and the holding portion cover portion 112 is the holding portion base portion. In the state assembled to 111, the locking projection 112 a of the holding unit cover 112 abuts against the tip of the flexible arm 121 and can be prevented from falling outward in the width direction Y. As a result, the protector 1, the wire harness WH, and the holding mechanism 100 can reliably maintain the state in which the pair of split holding space portions 113A and 113B are separated by the protrusion 130 provided on the flexible arm portion 121. The corrugated tube C can be held more appropriately.

  Further, the protector 1, the wire harness WH, and the holding mechanism 100 described above restrict the corrugated tube C from dropping from the holding unit 110 along the axial direction X by the meshing unit 114 provided in the holding unit 110. can do. As a result, the protector 1, the wire harness WH, and the holding mechanism 100 can hold the corrugated tube C more reliably.
