PROBLEM TO BE SOLVED: To solve a problem that the configuration of a conventional device for straightening the end part of a pipe becomes complicated and time and labor necessary for maintenance thereof is increased since a drive mechanism configured of a plurality of gears or the like is used to cope with pipes with various thicknesses. SOLUTION: In the device for straightening the end part of a pipe, when a center axis of a punch 40 at an outer circumferential side is made to a first axis 61, an inner circumferential face of a first annular part 110 and an outer circumferential face of a housing 21 are arranged with a second axis 62 displaced from the first axis 61 as a center axis, and the inner circumferential face of the housing 21, a base 22 and a shaft 23 are arranged with a third axis 63 displaced from the second axis 62 as a center axis. A relative angle position of the housing 21 along a circumferential direction to the first annular part 110 is adjusted and the displacement amount of the third axis 63 to the first axis 61 is adjusted, so that a width 50a of a gap 50 for straightening is adjusted.
