Abstract: In a linear drive device, a movable member is driven using a guide shaft and a lead screw supported by a bracket. Since a nut mechanism, which with the lead screw configures a feed screw mechanism, is provided with a first spring between two nuts, it is possible to limit rattling of the nuts with respect to the lead screw. Of the two nuts, the first nut provided on the side opposite a motor and a first plate is not able to move relative to the movable member in the axis direction. As a result, when a member to be driven is loaded on the movable member and the movable member is driven in the direction approaching the first plate, the first plate and members disposed therearound are not susceptible to interference by the member being driven.
