An apron feeder of a jaw crusher is provided to prevent a chute from moving horizontally by the weight of raw ores by circulating a chute in an endless track form by roller chains, while a guide plate is placed in a guide groove. In an apron feeder of a jaw crusher, a roller frame(300) combined with plural rollers(200) is installed at the upper part of a feeder frame(100). Roller chains(500) are connected by installing sprocket shafts(400) at both sides of the roller frame. A chute(600) is combined with the roller chain. The roller has a guide groove formed at the outer peripheral part and a shaft hole bored through the center. Both sides of a fixing shaft fitted with a bush are inserted into the shaft hole to be exposed. Collars are combined with the fixing shaft, respectively. A perforated groove is formed at the collar and the collar is joined to the roller frame by a bolt. The chute has a reinforcing plate welded with a guide plate and combined with the lower part of a horizontal chute plate. The guide plate is placed in the guide groove of the roller.
