The cables 10 and 11 are connected to the second introduction port 58.
In the longitudinal direction (almost horizontal direction) of the slide door 1
Displacement according to the open / close position of the is allowed. At that time, the boot member 59 on the cable guide 30 side is not
While being elastically deformed in the displacement direction (left-right direction in FIG. 3), the closed state of the opening of the introduction port 58 is maintained. Similarly, the boot member 59 on the cable guide 40 side is elastically deformed in the displacement direction of the cable 11 (vertical direction in FIG. 9), while being introduced into the inlet port 5.
The closed state of the opening 8 is maintained. Therefore, in each of the cable guides 30 and 40, it is possible to prevent rainwater and dust from entering the case 50 through the introduction port 58.

Further, the through hole 59 in the boot member 59.
Since the cross-sectional shape of E is the same circular cross-section as the cables 10 and 11, it is possible to set a small gap between the cables 10 and 11 and the through hole 59E or to eliminate the gap. As a result, it is possible to prevent rainwater and dust from entering the case 50 through the through holes 59E along the cables 10 and 11.

The boot member 59 has a displacement direction (almost horizontal direction) of the cables 10 and 11 in the introduction port 58.
Has a sufficient degree of freedom with respect to elastic deformation, and the elastic deformation in the vertical direction is suppressed by the amount of reinforcement by the upper and lower ribs 59D. That is, the rib 59D is used for the cable 1
While allowing elastic deformation of the boot member 59 in the 0 and 11 displacement directions, the boot member 59 is reinforced and rigidity is increased. As a result, when the gap between the outer peripheral surfaces of the cables 10 and 11 and the inner peripheral surface of the through hole 59E is reduced or eliminated, the influence of the frictional force between them can be avoided. That is, when the boss 59B tries to move leftward or rightward in FIG. 8 as the cables 10 and 11 move in the lengthwise direction due to the frictional force between them, the rib 59D causes the boss 59B to move. It is possible to suppress the movement of the boss portion 59B by regulating the position of. For example, being pulled by cables 10 and 11,
When the boss portion 59B is about to be wound into the case 50 from the left to the right in FIG. 8, the rib 59D can prevent the boss portion 59B from being wound.

Further, the cable guides 30 and 40 are mounted at fixed positions on the vehicle body side so that the boot member 59 is located below, thereby making it difficult for water and dust to enter the case 50 through the through hole 59E. be able to. Further, by setting the posture in which the cables 10 and 11 enter the through hole 59E to be upward, the invasion of water that travels along the cables 10 and 11 and tries to enter the case 50 is prevented, and a higher waterproof function is provided. Can be demonstrated.

The water that has entered the space S of the case 50 can be discharged to the outside through the water drain hole 52D.
In order to smoothly discharge the water, the cable guides 30, 40 are mounted in the front-rear direction and the width direction of the vehicle body so that the inner bottom surface of the lower case member 52 is inclined downward toward the drain hole 52D. It is desirable to tilt it.

(Other Embodiments) The cross-sectional shape of the through hole 59E in the boot member 59 may be substantially the same as the cross-sectional shape of the cables 10 and 11, and may have, for example, a circular cross section and an oval cross section. . In short, it suffices that the gap between the inner peripheral surface of the through hole 59E and the outer peripheral surfaces of the cables 10 and 11 can be reduced or eliminated.
