The two selection levers that respectively engage the two sets of knife and hook parts in the dobby machine are
The engaging operation is controlled by the pressing operation of a pusher lever that is disposed between the two selection levers and swings between the two selection levers, and the pusher lever is connected to a selector lever that moves forward and backward on the rear side. the selector lever is attracted to a suction means on the front side in order to maintain the forward position of the pusher lever, and the pusher lever has a head portion at a tip thereof having a pressing protrusion that protrudes toward both the selection levers. Each of the pressing protrusions performs the pressing operation by abutting the pressing abutting portions of the two selection levers when the pusher lever is in the forward position, and when the pusher lever is in the backward position, the pressing projections respectively contact the pressing contact portions of the two selection levers. In the control device for a dobby machine that performs a non-pressing operation by inserting the lever into a recess at the rear of the pusher lever, the head of the pusher lever is pressed at the boundary between the pusher and the recess in each of the selection levers. A control device for a dobby machine, characterized in that a locking projection is formed that projects from the pressing contact portion so that a rear surface side of a tip end of the projection can be locked.
