This accessory driving device for a vehicle is provided with: a first idler roller (8) disposed between an engine roller (6) and a first rotary roller (7); a second idler roller (9) disposed between the first rotary roller and a second rotary roller (5); a third idler roller (10) disposed between the second rotary roller and the engine roller; and a link mechanism (30) driven by one actuator. The link mechanism changes the position of the first idler roller so as to switch between a state in which the first idler roller and the engine roller make contact with the first rotary roller at the outer peripheral surfaces, and a state in which the first idler roller and the engine roller are separated from the first rotary roller. The link mechanism also changes the position of the second idler roller and/or the third idler roller so as to switch between a state in which at least one of the second idler roller and the third idler roller make(s) contact, at the outer peripheral surfaces, with two rollers that are adjacent to said at least one roller, and a state in which said at least one roller is separated from the two adjacent rollers. |
