Abstract
A door opening and closing apparatus includes a rail module including: a rail member extending along a front-and-rear direction; a drive device mounted on the rail member; and a supporting member coupled to a closing cable a part of which is wound around the rotating drum and that is hung on a closing inversion member and an opening cable a part of which is wound around the rotating drum and that is hung on an opening inversion member. The rail module is provided with the drive device fastened to an outside of a vehicle body such that a part of the drive device goes inside the vehicle body through an opening provided on the vehicle body. An outer diameter of the rotating drum of the drive device is made smaller than a maximum diameter of a deceleration mechanism for making the rotating drum rotate forward and backward.
