To attain the reduction of cost by more miniaturizing the structure of a guide part when a frame provided with a hemming blade is linearly moved.
A ascending and descending bracket 13 is attached to the main frame 11 ascendably and descendably and a hemming blade attaching part bracket 45 provided with an preliminary bending blade 15 and permanent bending blade 17 is installed on the descending bracket 13 approachably to and separably from a workpiece W on a hemming die 13. When the descending bracket 13 is elevated and lowered, the bracket is made into the state where the bracket is held with a cam follower 67 and LM roller 69 in the neighborhood of the upper end and with a cam follower 71 and an LM roller 73 in the neighborhood of the lower end to a guide rail 23 provided on the main frame 11. In this state, reaction force when preliminary bending and permanent bending is received with the cam followers 67, 71. Further, the cam follower 67 is an eccentric type and the clearance between itself and the guide rail 23 is adjusted by properly rotating the attached state.
