The riding surface 48B is inclined so as to increase. The protruding end surface of the protrusion 48 is a surface parallel to the outer surface of the elastic plate 49. This protruding end surface is located on the inner side of the outer surface of the first trunk portion 11A of the first half component 20A.

Next, an operation for fixing a bundle of electric wires to an object to be fixed will be described.
Here, the engagement component 30 is placed on the mounting portion 40 of the first half component 20A as shown in FIG. 2 (the posture in which the pair of elastic engagement pieces 32 face each other in the axial direction of the first trunk portion 11A). The case where it attaches to will be described.

  First, the engaging component 30 is set to a predetermined mounting posture (a posture in which the pair of elastic engaging pieces 32 are opposed to each other in the axial direction of the first trunk portion 11A), and the overhanging plate 34 is moved to the first branch portion 12A. When approaching, the overhanging plate 34 is arranged to face the insertion portion 45. When the engaging plate 30 is moved to the mounting portion 40 side so that the overhanging plate 34 extends along the outer surface of the first branch line portion 12A, the overhanging plate 34 is first inserted into the insertion portion 45. . At this time, since the engaging component 30 can be inserted so that the overhanging plate 34 extends along the outer surface of the first branch line portion 12A, alignment when the engaging component 30 is attached can be easily performed.

  The overhang plate 34 is smoothly guided into the insertion portion 45 by the guide plate taper surface 47 and the surrounding wall taper surface 46. Further, one second protrusion 37B of the pair of second protrusions 37B reaches the outside of the guide plate 42, and the guide plate 42 is inserted between the projecting plate 34 and the second protrusion 37B.

  When the engaging part 30 is further inserted, the engaging leg 31 is inserted into the mounting groove 41. At this time, the engaging leg 31 is smoothly drawn into the mounting groove 41 by the engaging leg taper surface 43. In addition, one end side of the overhanging plate 34 reaches the riding surface 48 </ b> B of the protrusion 48, and gradually rides on the protrusion 48.

  When the overhanging plate 34 rides on the protrusion 48 of the elastic plate 49, the elastic plate 49 is elastically displaced inward (side that widens the distance from the guide plate 42). In addition, the second protrusion 37 </ b> B arranged on the rear side in the insertion direction of the second protrusion 37 </ b> B reaches the outside of the guide plate 42, and the overhanging plate 34 is between the second protrusion 37 </ b> B and the guide plate 42. Will be inserted.

  When the engaging component 30 reaches a predetermined position (a position where the overhang plate 34 is completely accommodated in the insertion portion 45), the surface on the hinge portion 27 side of the peripheral surface of the recess 36 of the overhang plate 34 is the protrusion 48. As a result, the elastic plate 49 is elastically restored, and at the same time, the recess 36 and the protrusion 48 are fitted. Then, the engagement surface 48A of the protrusion 48 is in a state of facing the peripheral surface of the recess 36, and the overhang plate 34 is accommodated in the insertion portion 45 (sandwiched between the guide plate 42 and the elastic plate 49). ), And the displacement in the pulling-out direction from the insertion portion 45 is restricted. Further, the guide plate 42 is sandwiched between the second projecting portions 37 </ b> B and the overhang plate 34, and rattling between the engaging component 30 and the mounting portion 40 is suppressed. Furthermore, since the 2nd protrusion part 37B is distribute | arranged to the diagonal position of the engaging component 30, it is controlled reliably that the engaging component 30 inclines in an insertion direction. Thus, the engagement component 30 is held in a state of being attached to the attachment portion 40.

  Next, the protector 10 is attached to the branch part of an electric wire. Then, when the engaging leg 31 of the engaging part 30 is inserted into the fixed hole, the elastic engaging piece 32 is elastically deformed by sliding contact with the hole edge of the fixed hole, and elastic when the engaging leg 31 is inserted to a predetermined position. Returning, the locking portion 33 is locked to the hole edge of the fixed hole, and the engagement leg 31 is prevented from coming off. Thus, the bundle of wires is fixed to the fixed object.

  In the present embodiment, the engaging component 30 is attached to the protector 10 at a stage before the protector 10 is engaged with the branch portion of the electric wire. However, the present invention is not limited to this. For example, the protector is attached to the branch portion of the electric wire. After the attachment, the engaging part 30 may be attached to the protector 10.

  In the protector 10 of the present embodiment, the engaging component 30 can be attached by selecting not only the posture described above but also the posture. For example, the posture in which the pair of elastic engagement pieces 32 are arranged opposite to each other in the axial direction of the first branch line portion 12A (the orientation of the engagement component 30 is 90 with respect to the axis of the engagement leg 31 compared to the above-described posture. In the case of mounting with a changed posture), it is mounted as follows.

  The engagement component 30 is set to a predetermined mounting posture (a posture in which the pair of elastic engagement pieces 32 are opposed to the axial direction of the first branch line portion 12A), and the overhanging plate 34 is moved to the first branch line portion 12A in the same manner as described above. The engaging component 30 is moved to the mounting portion 40 side so as to be along the outer surface of the mounting portion 40. Then, the overhang plate 34 is first inserted into the insertion portion 45, and then the engagement leg 31 is inserted into the attachment groove 41. In addition, the pair of first projecting portions 37 </ b> A reaches the outside of the guide plate 42, and the guide plate 42 is inserted between the first projecting portion 37 </ b> A and the overhanging plate 34. In addition, the overhang | projection board 34 and the engagement leg 31 are each smoothly inserted by the guide plate taper surface 47, the surrounding wall taper surface 46, and the engagement leg taper surface 43 similarly to the above-mentioned.

  When the engaging part 30 is further inserted, the overhanging plate 34 rides on the riding surface 48B without being caught by the projection 48, and the elastic plate 49 is elastically displaced inward (side where the gap with the guide plate 42 is expanded). . When the engaging component 30 reaches a predetermined position (a position where the overhang plate 34 is completely accommodated in the insertion portion 45), the overhang plate 34 is elastically restored, and at the same time, the recess 36 and the protrusion 48 are fitted. To do. Thus, the overhang plate 34 is accommodated in the insertion portion 45 (sandwiched between the guide plate 42 and the elastic plate 49), and the displacement from the insertion portion 45 in the drawing direction is restricted. At this time, the guide plate 42 is sandwiched between the first projecting portions 37 </ b> A and the projecting plate 34, and rattling between the engaging component 30 and the mounting portion 40 is suppressed. Thus, no matter how the engagement component 30 is attached, rattling between the engagement component 30 and the attachment portion 40 can be suppressed by the first protrusion 37A or the second protrusion 37B. Thus, the engagement component 30 is held in a state of being attached to the attachment portion 40.

When attaching, etc., if the engaging leg 31 faces the opposite side to the fixed hole, the worst protector must be reattached, which is troublesome. However, according to this embodiment, since it is only necessary to reattach the engaging part 30 to the half part on the opposite side, flexibility when fixing the protector to the fixed object is great.
Moreover, in the state which does not attach the engaging component 30, it can be used in order to hold | maintain the branch direction of an electric wire simply, and it becomes rich in versatility.

  As described above, according to the present embodiment, when the engagement component 30 is attached to the attachment portion 40, any attachment posture in which the engagement component 30 changes its orientation by 90 degrees with respect to the axis of the engagement leg 31. Even so, the engaging leg 31 is inserted into the mounting groove 41, and the overhang plate 34 is inserted into the insertion portion 45 between the guide plate 42 and the elastic plate 49. Then, when the overhanging plate 34 rides on the protrusion 48 of the elastic plate 49, the elastic plate 49 is elastically displaced in a direction that widens the distance from the guide plate 42, and the engagement component 30 is brought into a predetermined position. When it reaches, the concave portion 36 of the overhanging plate 34 reaches the position of the protruding portion 48 and the elastic plate 49 is elastically restored, and at the same time, the concave portion 36 and the protruding portion 48 are fitted. Thus, the overhanging plate 34 is sandwiched between the guide plate 42 and the elastic plate 49 and the displacement in the pulling-out direction is restricted, so that the engaging component 30 is held in the state where it is attached to the attachment portion 40. Is done.

  In this way, the engagement component 30 can be attached to the attachment portion 40 in any attachment posture in which the orientation is changed by 90 degrees, so that the orientation of the engagement component 30 can be arbitrarily selected. And can be versatile.
