  (Procedure 3 .. Pressing Operation) The sheet member 90 set on the pressing portion 10 is pressed. Specifically, the actuator 70 is operated, and the second pressing member 13 is moved in the direction approaching the first pressing member 12 (the width direction of the mounting surface 11a) by the pair of actuator members 70a. By this movement, the vicinity of the end portions 90 a and 90 b of the sheet member 90 is pressed between the pressing portion 12 b of the first pressing member and the inner pressing surface 13 a of the second pressing member 13. As a result, the sheet member 90 is folded in half in a direction perpendicular to the longitudinal direction with the electric wire 82 interposed therebetween, and the inner adhesive surfaces facing each other with the electric wire 82 in the vicinity of the end portions 90a and 90b are pressed and bonded together. (See FIG. 3B). In addition, the auxiliary pressing portion 12 c performs an auxiliary operation for bonding the inner bonding surfaces of the sheet member 90 to the vicinity of the electric wire bundle just above the electric wire bundle. Further, the side cross-sectional contour on the side away from the pressing portion 12b has a curved shape with R so as not to damage the exterior surface of the sheet member 90 during bonding. Thus, the wire harness 80 with an exterior member in which the sheet member 90 is attached to the electric wire 82 is completed. In addition, the space | interval of the inner side press surface 12a of the 1st press member at the time of adhesion | attachment and the inner side press surface 13a of the 2nd press member 13 is a space | interval of the grade which the outer diameter of the electric wire 82 wrapped with the sheet | seat member 90 does not deform | transform. Is set to

  (Procedure 4 .. Removal operation of wire harness with exterior member) The completed wire harness with exterior member 80 is removed. Specifically, the cylinder 65 of the electric wire holding part 60 is operated, and the fitting member 64 is moved from the electric wire holding position to the retracted position by the actuator member 65a. Thereby, the electric wire 82 in the electric wire holding part 60 is released from the electric wire holding state. Next, the cylinder 51 of the connector holding part 50 is operated, the chuck 52a of the chuck 52 is released by the actuator member 51a, and the holding of the connector 81 is released. Subsequently, the cylinder 42 of the connector transport unit 40 is operated to move the chuck 41 downward, hold the connector 81 with the chuck claws 41a, and then move the chuck 71 upward. Next, another cylinder (not shown) is operated, and the cylinder 42 is conveyed by the actuator member in the take-out direction (the left side of the arrow in FIG. 1). Thereby, the taking-out operation of the wire harness 80 with the exterior member is completed.
