Embodiment Construction

[0035] Hereinafter, Embodiment 1 of the present invention will be described in detail using the drawings.

[0036] figure 1 Showing a side view of a single box car, figure 2 shows a plan view representing the installation structure of the sliding door to the vehicle body, image 3 A front view showing the outline of the drive unit (without cover), Figure 4 shows a perspective view representing a detail of the reel, Figure 5 A perspective view is shown showing the snap block fixed to the cable.

[0037] Such as figure 1 As shown, the vehicle 10 is a single box car, and a large opening 12 is provided at a side portion of a body 11 forming the vehicle 10 . Further, a slide door (opening and closing body) 13 for opening and closing the opening 12 is provided on a side portion of the vehicle body 11 . Such as figure 2 As shown, the sliding door 13 includes a roller assembly 13 a that moves along a guide rail 14 fixed to a side portion of the vehicle body 11 .

Abstract

A cross-sectional shape of an open-side cable 22a is formed into a round shape, and a cross-sectional shape of respective connecting units 52 between a pulley groove 50 of a pulley 46 and flange portions 51 is formed into a circular arc shape. Thus, it is possible to surely suppress damage of the open-side cable 22a caused by being strongly pressed to a corner as a conventional manner. Therefore, it is possible to improve durability of the open-side cable 22a, whereby it is possible to extend a maintenance cycle of a driving unit and obtain high reliability thereof.

Description

technical field [0001] The present invention relates to an opening-closing body drive device that drives an opening-closing body that opens and closes an opening. Background technique [0002] Conventionally, in a vehicle such as a sedan, a sliding door (opening and closing body) that slides in the vehicle front-rear direction is provided on a side portion of the vehicle body. Accordingly, it is possible to easily get on and off the vehicle, load and unload cargo, etc. through the large opening formed in the side portion of the vehicle body. Since the weight of the sliding door increases, an electric sliding door device capable of automatically opening and closing the sliding door is mounted on the vehicle. [0003] In the electric sliding door apparatus, the other end of the cable connected to the sliding door from the front-rear direction of the vehicle is guided to the drive unit via reversing pulleys provided at both ends of a guide rail fixed to the vehicle body. Then...
