  Further, if the lock piece is inserted into the vehicle fixing portion when the lid is fixed to the main body, space saving in the locked state can be realized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
FIG. 1 is a perspective view showing an embodiment of a holder according to the present invention, FIG. 2 is a view showing an open state of the holder shown in FIG. 1, (a) is a plan view thereof, and (b) is a plan view thereof. FIG. 3 is a front view showing a closed state of the holder shown in FIG. 1, FIG. 4 is a cross-sectional view showing an engagement state of the stay with the holder shown in FIG. 1, and FIG. (B) is a state diagram before a stay is inserted.

  The holder 1 is an integrally molded product made of a synthetic resin such as polypropylene, and has a semicircular cross-sectional main body 2 on which the wire harness W is placed as shown in FIGS. 1 and 2. On the inner peripheral surface of the main body 2, two ribs 2 a that engage with grooves of a corrugated tube (not shown) sheathed on the wire harness W are formed in an arc shape. A vehicle fixing portion 4 is connected to the free end of the main body 2. As shown in FIG. 4, a lock piece insertion hole 7 is formed in the vehicle fixing portion 4, and a lock piece engaging projection 9 is provided at the back of the lock piece insertion hole 7. Further, a stay insertion hole 8 having an H-shaped cross section is formed in the vehicle fixing portion 4, and a stay locking projection 10 is provided in the stay insertion hole 8 so as to be elastically swingable in the directions of arrows M and N. ing.

  Further, as shown in FIGS. 1 and 2, a semicircular cross-sectional lid 3 is rotatably connected to the main body 2 by a hinge 5, and a wire harness W is provided on the inner peripheral surface of the lid 3. Two ribs 3a that engage with a groove of a corrugated tube (not shown) that is packaged in the shape of an arc are formed in an arc shape. A lock piece 6 is connected to the free end of the lid 3.

  On the other hand, as shown in FIG. 5, the stay 12 has a substrate 12a having a U-shaped cross section, and a rectangular engagement hole 12b is formed in the substrate 12a.

  Since the holder 1 and the stay 12 have the above-described configuration, the following procedure is used when the wire harness W is attached to the vehicle using the holder 1.

  First, as shown in FIGS. 1 and 2, the wire harness W is placed on the main body 2 with the lid 3 of the holder 1 being opened.

  Next, the lid 3 is closed and the lock piece 6 is inserted into the lock piece insertion hole 7. Then, since the lock piece 6 is hooked on the lock piece engaging projection 9 and locked, the holder 1 is fixed to the wire harness W.

  Finally, the vehicle-side stay 12 is inserted into the stay insertion hole 8 of the vehicle fixing portion 4. Then, as shown in FIG. 4A, the stay 12 is positioned behind the lock piece 6 (rightward in FIG. 4A), and the engagement hole 12b is hooked on the stay locking projection 10 and fixed. It becomes a state. At this time, as described above, the stay insertion hole 8 has an H-shaped cross section and the stay 12 has a U-shaped cross section. The holder 1 can be attached in either the forward or reverse direction.

  As a result, the wire harness W is attached to the vehicle via the holder 1, and the attachment work of the wire harness W ends here.

  When the stay 12 is thus inserted into the vehicle fixing portion 4, the stay 12 is positioned behind the lock piece 6 as shown in FIG. 4A, and therefore the clearance C necessary to release the locked state Disappears. As a result, the locked state cannot be inadvertently released, so that the reliability of locking by the lock piece 6 is improved.

  In addition, the holder 1 is removed from the wire harness W before the stay 12 is inserted because a gap C necessary for releasing the locked state is secured as shown in FIG. In this case, the locked state can be easily released without damaging the lock piece 6.

  Further, when the lid 3 is closed and fixed to the main body 2, as shown in FIG. 3, the lock piece 6 enters the vehicle fixing portion 4, thereby realizing space saving in the locked state. Can do.

<Other embodiments>
In the above-described embodiment, the combination of the stay insertion hole 8 having an H-shaped cross section and the stay 12 having a U-shaped cross section has been described. Even when the stay 12 having an L-shaped cross section is combined, the holder 1 can be attached to the stay 12 in either the forward or reverse direction. Alternatively, a stay 12 having a U-shaped cross section may be combined with a stay insertion hole 8 having a U-shaped cross section in order to prevent erroneous assembly of the holder 1. In this case, since there is no possibility that the holder 1 is erroneously attached to the stay 12 in the reverse direction, a malfunction caused by the incorrect assembly of the holder 1 (for example, the holder 1 is damaged and forced to be reattached). In addition, it is possible to avoid that the wire harness W interferes with other components in the vehicle.

  In the above-described embodiment, the case where the wire harness W is attached to the vehicle has been described. However, a linear body other than the wire harness W (for example, hoses such as a washer hose, pipes such as a heat pipe) is mounted on the vehicle. The present invention can also be applied to the case of attaching to the case.

  The present invention can be widely applied to various industrial fields such as automobiles, airplanes, trains, manufacturing plants, electrical appliances, and OA equipment.
