PROBLEM TO BE SOLVED: To provide a driving device that can be wholly made smaller without deteriorating the operation accuracy of a door member.SOLUTION: A driving device 10 comprises: a screw 100 that rotates together with a rotating shaft MX of a motor M; a slider 200 arranged so as to surround at least a portion of the screw 100 from the outside; a door shaft 310 arranged so as to surround at least a portion of the slider 200 from the outside; a first conversion mechanism that converts the rotational motion of the screw 100 around a center axis CA into the linear motion of the slider 200 along the center axis CA; and a second conversion mechanism that converts the linear motion of the slider 200 along the center axis CA into the rotational motion of the door shaft 310 around the center axis CA. A door member 350 is driven in conjunction with the rotational motion of the door shaft 310.SELECTED DRAWING: Figure 1 |
