An absorbent article manufacturing device (100) comprises: a guide mechanism (110) which conveys an elastic member while fluctuating in an intersecting direction； a rotation mechanism (120) which conveys the elastic member which is supplied from the guide mechanism along the outer circumference face； and a cutting mechanism (130) which cuts the elastic member which is conveyed by the rotation mechanism. The guide mechanism further comprises: a first roller (111)； a second roller (112) which is positioned downstream of the first roller； and a fluctuation member (113) which axially supports the first roller and the second roller, and causes the second roller to fluctuate with a fluctuation axle (113a) in the direction of the supply of the elastic member to the first roller being the center thereof. The rotation mechanism further comprises: retaining members (122) which are positioned with gaps in the circumference direction and convey the elastic member； and a rotation drive member which changes the speed of the retaining members and moves the retaining members such that the gaps between the retaining members increase.La présente invention concerne un dispositif de fabrication d'article absorbant (100) comprenant les éléments suivants : un mécanisme de guidage (110) qui transporte un élément élastique tout en fluctuant dans une direction d'intersection ； un mécanisme de rotation (120) qui transporte un élément élastique procuré par ledit mécanisme de guidage le long de la surface de circonférence externe ； et un mécanisme de découpe (130) qui découpe l'élément élastique transporté par le mécanisme de rotation. Ledit mécanisme de guidage comprend en outre les éléments suivants : un premier rouleau (111) ； un second rouleau (112) positionné en aval du premier rouleau ； et un élément de fluctuation (113) qui soutient axialement le premier rouleau et le second rouleau, et entraîne la fluctuation du second rouleau selon un axe de fluctuation (113a) dans le sens de l'alimen
