PURPOSE: To feed only parts in the fixed attitude with different shapes by providing a plate-shaped part hooking/guiding projection on the lower edge of a conveying track, providing a recess on a track shift face at the preset distance from the projection, providing an air injecting means above the recess, tilting the part hooked on the recess with injection air, and discharging it to the outside over the projection.

CONSTITUTION: Parts 1 fed to a spiral track 27 in a train by the vibration of a vibrating part feeder are moved to a trough 40 and applied with the judgment by the first attitude judging device 52. The part 1 with its longitudinal direction set perpendicularly to the shift direction as shown in the figure has an attitude partially protruded on a recess H, it is pressed into the recess H by the air injected via an air injection pipe 60 and a through hole 61, the opposite edge is moved over a projection 57, and it is slid downward by the gravitational force. The part 1 not protruded to the recess H is not applied with the action of the injection air and is moved to the downstream as it is. Parts 1 can be surely fed in the preset attitude.
