To implement this, the present invention provides a pipe bending apparatus comprising: a bending shoe (20) which is formed on one side of a body frame (10) to be able to rotate by a rotating shaft (21); a handle rod (30) fixedly formed on the bending shoe (20); a rotating lever (40) configured to transmit a rotational force to the bending shoe (20); a roller bracket (50) which is provided under the bending shoe (20) and a plurality of support rollers (51) on both upper sides thereof for supporting a pipe (P); and moving blocks (60) which are connected by a rotating rod (61) at the lower portions thereof such that the roller bracket (50) can be rotated, wherein a guide plate (70) is provided on one side of the body frame (10) and guides the moving blocks (60) so as to horizontally slide-move together with the roller bracket (50), a manipulation lever (80) is provided on one side of the guide plate (70) so as to manipulate the sliding movement of the moving blocks (60), and a lever shaft (81) connected to the manipulation lever (80) is connected to the moving blocks (60) via a driving link (90) at the lower portion of the guide plate (70).
