A twist detecting device is capable of detecting twist of band-like cloth even though the thickness of the band-like cloth is changed, and a twist eliminating machine incorporates the twist detecting device. The twist detecting device is constructed so that cloth contactors 3a, 3b are supported by a pair of supporting axes 2a, 2b, the arcuate contacting portion r of these cloth contactors is brought into contact with band-like cloth w1 or w2, the respective cloth contactors 3a, 3b are caused to rock and to be displaced around their supporting axes by engagement with wrinkle lines of the band-like cloth, and the rocking and displacement are detected as twist information, wherein a cloth intermediate contacting member which is able to detect to the twist of band-like cloth is rockably provided around an intermediate supporting axis 13 juxtaposed between pair of supporting axes deep in a triangle-shaped space formed at the opposed sides of the arcuate contacting member of pair of cloth contactor, so that the cloth intermediate contacting member 12 is caused to rock and to be displaced around the intermediate supporting axes by engagement with the cloth contactors, and the rocking and displacement are detected as twist information of the band-like cloth.
