Abstract: An apparatus for adjusting direction of two component fasteners having a head element and a backing element for attachment to garment. The apparatus is a reciprocable driving device (8) for receiving the head element (7a) fed in from a hopper feeder (4a) through a chute (5) and charging it into a clamping device (12). The apparatus comprises an interlocking mechanism for rotating a support seat (9) for the head element (7a) in synchronism with the reciprocating movement of the driving device (8), a stopper (56) for stopping the rotation of the head element (7a), and a stopper exchanging device. The stopper exchanging device is a head element pressing section (43) comprising two layers (49, 50). The upper layer (50) having the stopper (56) is rotatable relative to the lower layer (49).
