PROBLEM TO BE SOLVED: To provide a hollow shape bending device in which a plurality of hollow shapes of different width can be treated with only one kind of a receiving member. SOLUTION: The hollow shape bending device comprises a fixed holding plate (4) and a movable holding plate (5) to hold both side walls (2), (3) of a hollow shape (1), receiving members (7), (8) to receive an inner wall (6) of the hollow shape (1) to be bent, a holding member (9) to hold a fixed side (1a) of the hollow shape (1), and a rocking lever (12) having a hooking member (11) to be abutted on an outer wall (10) of a bending side (1b) of the hollow shape (1). The respective receiving members (7), (8) comprise columnar parts (13), (14) protruded from inner surface of the respective holding plates (4), (5) by the length substantially twice the wall thickness of the hollow shape (1), and ring-shaped expansion parts (15), (16) provided on the tips of the columnar parts (13), (14).
