A fiber placement device includes an accumulation portion that stores and discharges a reinforcing fiber bundle including: a movable roller guided by a guide mechanism able to be moved in a constant movable range; a cylinder; a piston arranged within the cylinder; a coupling member coupling the movable roller and the piston; and an adjustment portion adjusting a force applied to the piston within the cylinder by discharging fluid from a space with the cylinder sealed on a side opposite the coupling member with respect to the piston within the cylinder or supplying the fluid into the space, the fluid is discharged from the space within the cylinder to apply a force to the piston to move the piston, a force is also applied to the movable roller through the coupling member to move the movable roller and thus a tension is applied to the reinforcing fiber bundle.
