A conveyor apparatus comprising: a conveying rod (18, 32) adapted to reciprocate along a conveyance path (8, 10) along which a workpiece is conveyed; a pusher member fixed to the conveying rod (18, 32) and configured to protrude from the conveying rod (18, 32); and a switching mechanism adapted to switch the pusher member, by turning the conveying rod (18, 32) a predetermined angle, between an engaged position where the pusher member engages with the workpiece and a retracted position where the pusher member is separated from the workpiece, characterized in that the switching mechanism includes a guide member related to the conveying rod (18, 32); the conveying rod (18, 32) includes a guided portion protruding from the conveying rod (18, 32); the guide member includes a guiding portion adapted to guide the guided portion of the conveying rod (18, 32); the guiding portion is configured to guide the guided portion into a closed loop using first and second guiding portions (25, 26) configured to extend in parallel to each other along the conveyance path (8, 10) and first and second coupling guide portions (27, 27) configured to couple ends of the first and second guiding portions (25, 26) to each other; the guide member is configured such that the guided portion makes a round of a guiding portion of the closed loop of the guide member through one reciprocating motion of the conveying rod (18, 32); the pusher member of the conveying rod (18, 32) assumes the engaged position when the guided portion of the conveying rod (18, 32) moves forward by being guided by the first guiding portion; and the pusher member of the conveying rod (18, 32) assumes the retracted position when the guided portion of the conveying rod (18, 32) moves backward by being guided by the second guiding portion. a conveying rod (18, 32) adapted to reciprocate along a conveyance path (8, 10) along which a workpiece is conveyed; a pusher member fixed to the conveying rod (18, 32) and configured to protrude from the conveying rod (18, 32); and a switching mechanism adapted to switch the pusher member, by turning the conveying rod (18, 32) a predetermined angle, between an engaged position where the pusher member engages with the workpiece and a retracted position where the pusher member is separated from the workpiece, characterized in that the switching mechanism includes a guide member related to the conveying rod (18, 32); the conveying rod (18, 32) includes a guided portion protruding from the conveying rod (18, 32); the guide member includes a guiding portion adapted to guide the guided portion of the conveying rod (18, 32); the guiding portion is configured to guide the guided portion into a closed loop using first and second guiding portions (25, 26) configured to extend in parallel to each other along the conveyance path (8, 10) and first and second coupling guide portions (27, 27) configured to couple ends of the first and second guiding portions (25, 26) to each other; the guide member is configured such that the guided portion makes a round of a guiding portion of the closed loop of the guide member through one reciprocating motion of the conveying rod (18, 32); the pusher member of the conveying rod (18, 32) assumes the engaged position when the guided portion of the conveying rod (18, 32) moves forward by being guided by the first guiding portion; and the pusher member of the conveying rod (18, 32) assumes the retracted position when the guided portion of the conveying rod (18, 32) moves backward by being guided by the second guiding portion.
