To provide a push bar conveyer for a bulk substance wide in a width, thin in thickness and inclined upwards.

In the push bar conveyer wherein push bars formed with a large number of successive saw-tooth-like grooves inclined along a longitudinal direction are provided on both faces of a thick-plate-like push member to make a face with the grooves right-angled to a bottom face of a trough, and wherein fellow end faces of tops in the saw-tooth-like grooves of the adjacent push bar members are brought into the condition where they contact each other during reciprocation motion or have a small clearance, so as to be juxtaposed longitudinal-directionally on a bottom plate, a stroke in the reciprocation motion of the each push bar is brought into at least 1.2 times of a pitch in the saw- tooth-like grooves to move the supplied bulk substances toward a front part of the conveyer in order.
