PROBLEM TO BE SOLVED: To provide a drag device in which the magnitude of drag forces is visible easily without using electrical parts.SOLUTION: A drag device in one embodiment includes: a friction material for applying a braking force to a spool a biasing spring for generating a biasing force to the friction material according to a displacement amount to the axial direction of the spool shaft a nut moving in an axial direction of the spool shaft according to the operation by an operator, and changing the displacement amount of the biasing spring by the movement a pressing member provided between the friction material and the biasing spring, and pressing the friction material according to the biasing force of the biasing spring an operation member for moving the nut according to the operation by the operator and a slider provided with at least a portion in a position visible by the operator, and displaying the displacement amount by moving to the direction substantially perpendicular to the axial direction of the spool shaft according to the change of the displacement amount of the biasing spring by the nut. Thereby, the drag device functions as the drag device for braking the rotation of the spool.
