FIG.

First, an operator sets the grommet 100 in the grommet holding part 20 (refer Fig.6 (a)).
Here, the worker fits the grommet 100 into the grommet fitting groove 22 so that the positioning projection 110b of the grommet 100 fits into the positioning groove 22c.
Thereby, the grommet 100 is hold | maintained by the grommet holding | maintenance part 20 with a predetermined attitude | position.

  Thereafter, the worker sets the connector C in the connector holding portion 10 (see FIG. 6B).

Thereafter, the worker brings the grommet holding portion 20 and the wire guide portion 30 into contact with each other (see FIG. 6C). More specifically, the worker slides the wire guide portion 30 toward the grommet holding portion 20 until it abuts on the grommet holding portion 20.
As a result, the corresponding wire guide grooves 34 of the wire guide portion 30 are arranged to be close to the respective wire insertion holes 110 a of the grommet 100 held by the grommet holding portion 20.

  Thereafter, the operator holds the pair of branch pieces 120b, 120b of the grommet 100 in a state of being bent in a direction away from each other by the pair of guide pins 23, 23 (see FIG. 7D). Thereby, since the electric wire W can be inserted in the grommet 100 in a state where the electric wire W is exposed from the cylindrical portion 120 of the grommet 100, the operator can easily insert the four electric wires W into the grommet 100. .

  Thereafter, the worker stretches the four electric wires W extending from the connector C (see FIG. 7 (e)). More specifically, the worker extends the four electric wires W to the periphery of the grommet holding portion 20. At this time, each electric wire W is extended so that each electric wire W may not cross. In this embodiment, the operator stretches each wire W so that the two wires W inserted into the lower wire guide groove 34 and the two wires W inserted into the upper wire guide groove 34 are separated. .

Thereafter, the worker inserts the two electric wires W into the lower electric wire guide groove 34 of the electric wire guide portion 30 (see FIGS. 8 (f), (g), (h)). Here, the two lower wire guide grooves 34 are grooves formed in the wire guide main body portion 31, and the groove opening 34 a is closed by the movable lid portion 32. Therefore, the two electric wires W are guided to the electric wire insertion holes 110 a of the grommet 100 without being separated from the lower electric wire guide grooves 34.
The two electric wires W are inserted into the grommet 100 so as to be pulled out from the cylindrical portion 120 with a length that allows the operator to hold the electric wires W, as shown in FIG.

Thereafter, the worker inserts the two wires W into the two upper wire guide grooves 34 of the wire guide portion 30 (see FIGS. 9I and 9J).
Here, the two upper wire guide grooves 34 are grooves formed in the movable guide groove 33, and the groove opening 34 a is closed by the movable lid 32. Therefore, the two electric wires W are guided to the electric wire insertion holes 110 a of the grommet 100 without being separated from the upper electric wire guide grooves 34.
In addition, as shown in FIG.9 (j), the two electric wires W are cylindrical with the length which an operator can hold | grip each electric wire W similarly to the two electric wires W inserted in the lower electric wire guide groove 34. The grommet 100 is inserted so as to be pulled out from the section 120 side.

Thereafter, the operator slides the grommet holding portion 20 toward the connector holding portion 10, and causes the grommet holding portion 20, the wire guide portion 30, and the connector holding portion 10 to abut on adjacent members in the sliding direction ( (See FIGS. 10 (k) and (l)).
Here, when the grommet holding portion 20 is slid toward the connector holding portion 10, the wire guide portion 30 is also slid toward the connector holding portion 10 together with being pushed by the grommet holding portion 20.
Further, the operator slides the grommet holding portion 20 toward the connector holding portion 10 until the wire guide portion 30 abuts on the positioning contact portion 13 of the connector holding portion 10.
Further, when the wire guide portion 30 abuts on the positioning contact portion 13 of the connector holding portion 10, the grommet holding portion 20 is positioned and disposed. Thereby, the grommet 100 is positioned and arranged with respect to the four electric wires W.
In addition, the grommet holding | maintenance part 20 and the electric wire guide part 30 slide in the state where the four electric wires W were settled in each electric wire guide groove 34 of the electric wire guide part 30, and the four electric wires W are made into linear form, In addition, since the state of holding in the predetermined position can be maintained, the four electric wires W are not twisted or entangled.

  Then, an operator pulls each electric wire W in order to take looseness of each electric wire W in the state which the grommet holding | maintenance part 20, the electric wire guide part 30, and the connector holding | maintenance part 10 contact | abutted in the slide direction. See FIG. 10 (m)).

Thereafter, the operator removes the pair of branch pieces 120b of the grommet 100 from the respective guide pins 23 (see FIG. 11 (n)).
Here, the four electric wires W are cylindrical portions by elastically restoring the branch portions 120b, 120b to make the distance between the pair of slits 120a, 120a small, so that the cylindrical portion 120 of the grommet 100 makes Fits within 120.

Thereafter, the operator slides the grommet holding portion 20 away from the wire guide portion 30, thereby removing the grommet 100 from the grommet holding portion 20 (see FIG. 11 (o)).
Here, when the grommet holding portion 20 is slid away from the wire guide portion 30, the grommet 100 is pulled out from the opening 22a formed in the wall of the grommet fitting groove 22 on the side of the wire guide portion 30.
Thus, only by sliding the grommet holding portion 20 away from the wire guide portion 30, the grommet 100 is naturally pulled out from the opening 22a formed in the wall of the grommet fitting groove 22 on the side of the wire guide portion 30. Therefore, the mounting position of the grommet 100 is difficult to shift.
Further, by removing the grommet 100 from the grommet holding portion 20 before removing the four electric wires W from the electric wire guide grooves 34 of the electric wire guide portion 30, it is possible to prevent the attachment position of the grommet 100 from being shifted by a later operation. .

  Thereafter, the operator grasps the product from both sides of the wire guide portion 30 (see FIG. 12 (p)). Thereby, each electric wire W can be removed from each electric wire guide groove 34, without applying a load to the four electric wires W.

Thereafter, the operator can take out each electric wire W from the groove opening 34a of each electric wire guide groove 34 by moving the movable guide groove portion 33 (see FIG. 12 (q)).
Here, the operator rotates the movable guide groove 33 around the axis of the hinge 35. Then, the movable lid portion 32 is also rotated in the same direction while being spaced apart from the movable guide groove portion 33, so that the two lower wire guide grooves 34 of the wire guide main body portion 31 and the movable guide groove portion 33 2. A gap is formed between each of the upper wire guide grooves 34 and the movable lid portion 32. As a result, the wires W can be removed from the wire guide grooves 34 whose groove openings 34 a are closed by the movable lid 32.

  Thereafter, the worker takes out four electric wires W from the electric wire guide portion 30 (see FIG. 12 (r)).

  Finally, the operator completes this operation by removing the connector C from the connector holding portion 10.
