To provide a small-sized and lightweight posture controller of a nozzle, which has excellent general purpose properties of the model, can readily be operated and has high degree of freedom of control.

In a multicolored picking loom in which a plurality of picking nozzles share picking positions and in picking, the nozzles are selectively moved to the picking positions, this posture controller is composed of a holding member for holding each nozzle, a bracket uniform for supporting the holding member on a loom frame and a driving part for shaking and driving the bracket unit. The holding member is combined with the bracket unit through mutually spherical fitting in a state in which either one encloses the other. The spherical fitting part is arranged in the vicinity of the shaking central axis of the bracket unit or the nozzle is held by one end of the holding member and the holding member is extended toward the shaking central axis of the bracket unit and the other end of the holding member is held by the bracket unit. The holding member is combined with the bracket unit through mutually spherical fitting in a state in which either one encloses the other.
