。[Claims for Utility Model Registration] A frame made of synthetic resin that forms a card conveyance path; a tension roller that protrudes and presses a magnetic card; and a tension spring that presses and biases a roller shaft that rotatably supports the tension roller in the direction of the card conveyance path; a pair of bearings having U-shaped grooves that support each shaft end of the roller shaft; a pair of retaining walls located outside the bearings to restrict movement of the roller shaft in the thrust direction; and the tensioner. A spring fixing portion to which the spring is fixed, and a spring stopper for regulating the movement of the tension spring in the front-rear and left-right directions are respectively protruded integrally with the frame, and the tension spring is formed in a U-shape in plan view. , its base is fixed on the spring fixing part, each end presses the shaft end of the roller shaft and contacts the outer surface of each bearing part, and the tension roller side surface and the bearing part are connected to each other. A tension roller support structure in a card reader, wherein a gap is set larger than a gap between an end face of the roller shaft and the retaining wall.
