The protrusion 66 is arranged between the electric wire 21 and the exterior member 25 in the radial direction of the electric wire 21.

Therefore, since the protruding portion 66 of the retainer 61 is arranged between the exterior member 25 and the electric wire 21, the end portion 25c of the exterior member 25 is suppressed from coming into contact with the insulating coating 23 of the electric wire 21. Therefore, the electric wire 21 can be protected from friction between the electric wire 21 and the end portion 25c of the exterior member 25.

The protrusion 66 of the first retainer member 62A and the protrusion 66 of the second retainer member 62B have a semi-cylindrical shape, and the first retainer member 62A and the second retainer member 62B form a cylindrical protrusion. This cylindrical protrusion is inserted into the exterior member 25 from the end 25c of the exterior member 25. Therefore, the electric wire 21 protruding from the end portion 25c of the exterior member 25 is covered with the cylindrical protruding portion, so that the electric wire 21 is suppressed from being exposed and the electric wire 21 can be protected.

Further, when a part of the protruding portion 66 is exposed from the exterior member 25, the exterior member 25 can be fixed to the retainer 61 by wrapping the protruding portion and the exterior member 25 with tape, and the exterior member 25 can be fixed to the retainer 61.

Note that FIG. 6 shows a state in which the second split retainer 61B is fixed. In FIG. 6, the electric wire 21 and the seal member 51 are omitted. Then, the first retainer member 62A and the second retainer member 62B are locked to each through portion 43 by the first division retainer 61A. Therefore, the number of steps is reduced as compared with the case where the first retainer member and the second retainer member are respectively locked to each through portion 43.

Further, a plurality of first retainer members 62A for fixing each exterior member 25 are connected by a first connecting member 68A, and a plurality of second retainer members 62B for fixing each exterior member 25 are connected by a first connecting member 68A.
