PIPE BENDER

PROBLEM TO BE SOLVED: To realize a bender capable of bending plural pipes having different outer diameters at the same radius and also bending a pipe having the same outer diameter at different radiuses. SOLUTION: A pair of handles 50, 51 are provided, one side of handle 50 is fixed to a fixed shoe 52 for bending a pipe, a pipe stopper 59 is provided in the fixed shoe 52, moreover the fixed shoe 52 is provided with a shaft 53 orthogonal to the handle 50, plural nearly semicircular recessed grooves 55, 56 having the shaft 53 as the center are formed, the radiuses of curvature of the cross sections of the recessed grooves 55, 56 are different each other, further the distances from the centers of the radiuses of curvature of respective recessed grooves 55, 56 to the shaft 53 are equal, and recessed grooves 57, 58 correspondent to the recessed grooves 55, 56 of the fixed shoe 52 are formed in the pipe stopper 59. The other side of the handle 51 is fixed to a movable shoe 54 capable of turning around the shaft 53 of the fixed shoe 52 as the center, and recessed grooves 60, 61 correspondent to the recessed grooves 55, 56 of the fixed shoe 52 are formed in the movable shoe 54.
