As a result, the cover member is locked to the container body. In the inside of the container body, the locked portion is pressed against the locking portion by a contained object such as a wire harness.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 to 4 show a protector provided with a locking mechanism for a cover member according to the present invention.

In the figure, reference numeral 10 is a protector body as a container body,
Side walls 12 and 12 are provided on both sides of the bottom plate 11 along the longitudinal direction, and are formed to have a generally U-shaped cross section.

Further, reference numeral 20 in the drawing denotes a cover member, which is the protector body 1
The side plate 22 having a height lower than that of the side wall 12 is provided on both sides of the cover plate 21 that covers the upper end opening of 0 along the longitudinal direction, and the side plate 22 is also formed into a substantially U-shaped cross section as a whole. Can be detachably attached.

The protector configured as described above is provided with a lock mechanism for the cover member 20 that does not easily come off during transportation or the like.

That is, a plurality of locking protrusions 13 serving as locking portions are provided at positions near the upper ends of the inner surfaces of the side walls 12, 12, respectively (in the drawing, two protrusions are provided near one end and the other end in the longitudinal direction of the sidewall 12).
4 pieces in total) are provided. A locking tongue piece 23 is provided on the inner surface of the lid plate 21 at a position facing each locking projection 13, and the locking projection 13 is engaged with the locking tongue piece 23 in a disengageable manner. A locking hole 23a is provided as a locking portion.

Here, the locking projection 13 has a slanted surface 13a and a flat surface 13a.
b and the right-angled surface 13c are continuously provided. Also,
The locking tongue piece 23 faces the side plate 22 with a space corresponding to the plate thickness of the side wall 12. Further, the bottom plate 11 is provided with a hole 11a into which a tool such as a screwdriver for removing the locking tongue 23 from the locking projection 13 is inserted near the side wall 12, and the wire harness-containing article W is located inside the hole 11a.
Hole 11 into which a substantially U-shaped jig 30 for converging and holding
b is provided. Further, the lid plate 21 has holes 21a, 21 through which the upper ends of the two legs 31, 31 of the jig 30 pass.
a is provided.

In order to converge and fix the wire harness W with the protector, first, as shown in FIG. 1, the two legs 31 and 31 of the jig 30 are inserted into the holes 11b on the jig base, and the protector main body 10 is inserted. Make it protrude inside. Next, as shown in FIG. 2, the wire harness W is housed between the two legs 31 and 31, and the cover member 20 is then put on the protector body 10. At this time, the leg 31 secures a space into which the locking tongue 23 is inserted inside the protector body 10 (see FIG. 3). In this state, the locking projection 13 is locked in the locking hole 23a. In this case, first of all, the locking tongue piece 23 is formed by the slope 13a.
Bends away from the inner surface of the side wall 12. Then, when the free end of the locking tongue 23 rides on the flat surface 13b and reaches the right-angled surface 13c, it is returned to the vertical state by the restoring elastic force of the locking tongue 23 itself, and the locking hole 23a is engaged. It is locked to the stop projection 13. After the locking projection 13 is locked in the locking hole 23a in this way, the legs 31 and 31 are pulled out from the hole 11b. As a result, the wire harness W is released from the restraint of the legs 31 and 31 inside the protector body 10, and the locking tongue piece 23 is pressed against the inner surface side of the side wall 12 by the wire harness W as shown in FIG. The stop hole 23a is pressed against the locking projection 13 side).

If the lock mechanism (locking projection 13, locking tongue 23, locking hole 23a) that locks the cover member 20 is hidden inside the protector body 10 as described above, there is no possibility that it will be caught by another object. Absent. Further, since the locking tongue piece 23 is pressed against the inner surface side of the side wall 12 by the wire harness W, the locking between the locking hole 23a and the locking projection 13 is reliably maintained even when vibration or the like is applied.

To remove the cover member 20 from the protector body 10, a tool such as a screwdriver may be inserted through the hole 11a to bend the locking tongue piece 23 in a direction away from the inner surface of the side wall 12.

In the above embodiment, the locking projection 13 is formed on the inner surface of the side wall 12.
Although the locking tongue 23 is provided with the locking hole 23a, the locking recess is provided on the inner surface of the side wall 12, and the locking tongue 23 is detachably engaged with the locking recess. A locking protrusion that stops may be provided.

[Effects of the Invention] As described above, according to the locking mechanism of the cover member of the present invention, since the locking portion and the locked portion are inside the container body, for example, the locked portion is caught on another object. Therefore, there is no risk that the locked portion will come off the locking portion. Moreover, since the locked portion is pressed against the locking portion side by the elastic force and the contained object and locked to the locking portion, the cover member can be removed even if a large external force is applied to the cover member. There is no.

Therefore, the cover member can be securely fixed to the container body. Moreover, since the contained object (wire harness) is held by the jig for converging and holding the contained object when the cover is attached, the cover member can be easily locked.
