PURPOSE: To provide a roller type pallet conveyor device capable of conveying plural pallet continuously and keeping the spacing of the respective pallets constant.

CONSTITUTION: A roller type pallet conveyor device is provided with a shuttle member 12 which is a horizontal rectangular movable member extended longitudinally being disposed between a lateral pair of roller conveyors 3 so as to repeat longitudinal reciprocating movement with the moving stroke of the length obtained by adding the longitudinal clearance measure of a pallet 06 to the length of the pallet, and plural movable feed claws disposed on the shuttle member 12, at moving stroke spaces in such a way as to be raised/leveled. In a feed stroke, these feed claws are erected simultaneously so as to push the rear face of each pallet 06 by the upper ends thereof, and in a return stroke, these feed claws are leveled and then automatically erected by the rear end of the pallet 06 after passing through the lower face of each pallet 06.
