In the following, for convenience of explanation, each direction is newly defined as indicated by arrows in FIGS. 4 and 5 separately from the directions in the explanation of FIGS. 1 to 3.

  The harness holding member 35 has a groove shape having a path opening 44, a path member 40 formed so as to be able to accommodate the wire harness 34, and an elastically deformable groove shape having a cover opening 45. A cover 41 provided so as to cover the path opening 44 by allowing the opening 45 side to enter the path member 40 from the path opening 44 and a plurality of protrusions projecting inward from the inner side surface of the path member 40 The engagement protrusion 42 and a plurality of engagement holes 43 provided on the side surface of the cover 41 so as to engage with the engagement protrusion 42 when the cover 41 enters the inside of the path member 40 are provided.

  The wire harness 34 is connected to electrical components such as the fans 30a and 30b and the control board 31, and is configured by bundling a plurality of electric wires used for power supply and signal communication.

  The path member 40 extends along the arrangement path of the wire harness 34 (the front-rear direction in FIGS. 4 and 5). The path member 40 is formed integrally with the wiring guide member 6 by, for example, an insulating resin material. Specifically, the path member 40 has a bottom portion 40a that forms part of the wiring guide member 6, and a pair of left and right wall portions 40b that extend upward from the left and right ends of the bottom portion 40a. Therefore, the path member 40 is formed to have a groove shape having the path opening 44 above.

  The cover 41 is made of, for example, a permeable film material (for example, PET resin). The cover 41 is a member fitted to a part of the extending path member 40. Specifically, the cover 41 has a ceiling portion 41a that can be fitted into the path opening 44, and a pair of left and right side portions 41b that extend downward from the left and right ends of the ceiling portion 41a. . Therefore, the cover 41 is formed in a groove shape having a cover opening 45 below. That is, the cover 41 is configured to have a shape in which the path member 40 is made slightly smaller and inverted in the vertical direction when viewed from the front.

  A pair of left and right engaging projections 42 project from the inner side surfaces of the pair of left and right wall portions 40b so as to be substantially opposed (only one on the right side is shown in FIGS. 4 and 5). Although illustration is omitted, a plurality of the pair of engaging protrusions 42 are provided on each wall portion 40b of the path member 40 at a predetermined interval. Each engagement protrusion 42 is provided at the substantially vertical center of the wall 40b. Each engagement protrusion 42 is formed in a substantially rectangular parallelepiped shape.

  A pair of engagement holes 43 are formed on both side surface portions 41 b of the cover 41 so as to correspond to the pair of left and right engagement protrusions 42 arranged to face each other. Each engagement hole 43 is a rectangular opening, and is formed through substantially the center of the side surface portion 41b in the vertical direction.

  Next, a procedure for causing the harness holding member 35 to hold the wire harness 34 will be described. Here, it is assumed that the cover 41 is attached to a pair of engaging protrusions 42 provided at an arbitrary position of the extending path member 40.

  First, an operator connects a connector (not shown) connected to an end of the wire harness 34 to a predetermined electronic component, and accommodates the wire harness 34 in the path member 40 from the path opening 44 ( (See FIG. 4). That is, the wire harness 34 is disposed in a space surrounded by the bottom portion 40a and each wall portion 40b.

  Subsequently, the operator deforms each side surface portion 41 b of the cover 41 inward with the cover opening 45 facing the path opening 44, and causes the cover 41 to enter the path member 40. The operator pushes the ceiling 41a of the cover 41 and moves the cover 41 downward. As the cover 41 advances (moves downward), the lower end portion (the end portion on the cover opening 45 side) of each side surface portion 41b of the cover 41 comes into contact with the inclined surface 42a of each engagement protrusion 42. When the cover 41 further advances, the lower end portions of the side surface portions 41b of the cover 41 slide on the inclined surfaces 42a of the engagement protrusions 42, and the side surface portions 41b of the cover 41 are subjected to their own elastic force. Deforms further inward.

Thereby, each engagement protrusion 42 engages with each engagement hole 43, and the cover 41 is attached so as to close the path opening 44 of the path member 40. In this state, the wire harness 34 is accommodated in the accommodation space S surrounded by the path member 40 and the cover 41. As described above, the wire harness 34 is held by the harness holding member 35.

  According to the harness holding member 35 according to the first embodiment described above, the cover 41 has elasticity, has a shape in which the path member 40 is substantially reversed, and is engaged by entering the inside of the path member 40. The protrusion 42 engages with the engagement hole 43 and is attached to the path member 40 in a state in which separation is restricted. Therefore, a high degree of dimensional accuracy is not required in the manufacture of the cover 41, and the cover 41 can be manufactured simply by setting a thickness having an elastic force capable of maintaining the engaged state. Thereby, the manufacturing cost of the cover 41 can be reduced. Further, the wire harness 34 can be held in the path member 40 so as not to be detached by a simple procedure of inserting the cover 41 into the path member.

  Moreover, since the cover 41 has transparency, an operator (user) can check the wire harness 34 in the path member 40 without removing the cover 41.

As shown in FIG. 11, the harness holding member 70 includes a path member 40, an elastically deformable groove-shaped cover 71, and a plurality of engagement protrusions 72 that protrude inward from the inner surface of the path member 40. And an engaging portion 73 configured by a part of the cover 71 engageable with the engaging protrusion 72 when the cover 71 enters the inside of the path member 40. Since the cover 71 is the same as the cover 41 according to the first embodiment except that the engagement hole 43 is omitted, a detailed description thereof is omitted.

  Each engagement protrusion 72 is provided so as to face the upper end portions of the pair of left and right wall portions 40b. Since each engagement protrusion 72 is the same as the engagement protrusion 42 according to the first embodiment except for the arrangement position, detailed description thereof is omitted.

  Next, a procedure for causing the harness holding member 70 to hold the wire harness 34 will be described. Here, it is assumed that the cover 71 is attached to a pair of engaging protrusions 72 provided at arbitrary positions of the extending path member 40.

  First, the operator accommodates the wire harness 34 in the path member 40 from the path opening 44, deforms the side surfaces 41 b of the cover 71 inward, and causes the cover 71 to enter the path member 40. At this time, the lower end portion of each side surface portion 41b slides on the inclined surface 42a of each engagement protrusion 72, and each side surface portion 41b of the cover 71 is deformed further inward against its own elastic force. To do.

  And if the cover 71 moves to the lower side of each engagement protrusion 72, each side part 41b will return to an original position with an own elastic force (refer FIG. 11). At this time, the lower end portion of each side surface portion 41 b of the cover 71 is in contact with the bottom portion 40 a of the path member 40, and the upper surface of the ceiling portion 41 a of the cover 71 is in contact with the lower surface 72 a of each engagement protrusion 72. Therefore, a part of the upper surface of the ceiling portion 41 a is an engaging portion 73 that engages with the engaging protrusion 72. As described above, the wire harness 34 is accommodated in the accommodation space S, and the wire harness 34 is held by the harness holding member 70.

  According to the harness holding member 70 according to the third embodiment described above, the cover 71 has elasticity, and enters the inside of the route member 40 so as to cover the route opening 44. Therefore, a high degree of dimensional accuracy is not required in manufacturing the cover 71, and the cover 71 can be manufactured simply by setting a thickness having an elastic force capable of maintaining the engagement with the engagement protrusion 72. Thereby, the manufacturing cost of the cover 71 can be reduced. Further, the wire harness 34 can be held on the path member 40 so as not to be detached by a simple procedure of inserting the cover 71 into the path member 40.

<Modification of Third Embodiment>
Next, a harness holding member 80 according to a modification of the third embodiment will be described with reference to FIGS. 10 and 12. Here, FIG. 10 is a perspective view showing the harness holding member 80, and FIG. 12 is a cross-sectional view schematically showing the harness holding member 80. In the following, for convenience of explanation, each direction is defined as indicated by an arrow in FIG. In the following description, the same reference numerals are given to the same configurations as those of the harness holding member 70 according to the third embodiment described above, and the description thereof is omitted.

  In the harness holding member 70 according to the third embodiment described above, the cover 71 is formed in a groove shape. However, in the harness holding member 80 according to this modification, the cover 81 is formed in a thin plate shape. Is different.

  As shown in FIG. 10, the harness holding member 80 according to the modification of the third embodiment is provided on a part of the wiring guide member 7 (next to the left of the harness holding member 70). As shown in FIG. 12, the cover 81 omits the pair of left and right side portions 41 b from the cover 71 and is configured only by the ceiling portion 41 a.

  In order to cause the harness holding member 80 to hold the wire harness 34, the cover 81 is disposed so as to be sandwiched between the wire harness 34 in the path member 40 and the lower surface 72a of each engagement protrusion 72 (see FIG. 12). . Therefore, a part of the upper surface of the cover 81 serves as an engaging portion 82 that engages with the engaging protrusion 72. Thereby, the wire harness 34 is held by the harness holding member 80.

  In the harness holding members 35 and 50 according to the above-described third embodiment and modifications thereof, the number of the engagement protrusions 72 that hold the one cover 71 or 81 is arbitrary.

  In addition, in description of each above-mentioned embodiment (a modification is included), although the wire harness 34 which bundled the some electric wire was hold | maintained, it is not limited to this. The harness holding members 35, 50, 60, 70, 80 can hold arbitrary cord-like bodies (wires) such as at least one electric wire or optical fiber cable.

  The above description of each embodiment (including modifications) of the present invention describes preferred embodiments of the harness holding members 35, 50, 60, 70, and 80 according to the present invention.
