A roller tunnel kiln includes a lower kiln body half composed integrally of a kiln bottom and a pair of transversely spaced lower kiln side wall halves which are made of refractory brick, a pair of endless chains disposed respectively on transversely opposite sides of the lower kiln body half outside thereof, the endless chains being movable forward along the lower kiln side wall halves at a height substantially equal to upper ends of the lower kiln side wall halves and movable backward along the lower kiln side wall halves at a height lower than the kiln bottom, a drive device for driving the endless chains in synchronism with each other, couplings mounted at regular intervals on link plates or link pins of each of the endless chains, feed members having opposite ends gripped by respective couplings and movable in a longitudinal direction of the lower kiln body half directly thereabove in response to the endless chains being synchronously driven, the feed members being made of a heat-resistant material and having a length larger than the width of the lower kiln body half, and a suspended upper kiln body half composed integrally of a kiln ceiling and a pair of transversely spaced upper kiln side wall halves which are made of refractory brick, the upper kiln body half being disposed with a clearance wide enough to allow the feed members to be moved therethrough being defined between lower end surfaces of the upper kiln side wall halves and upper end surfaces of the lower kiln side wall halves.
