This slider is made of synthetic resin and is attached to a shutter for opening and closing the head insertion hole of a case in which a disk-shaped recording medium is housed, and makes sliding contact with the edge of the case. It has a support part and an extension part extending from the support part, and an engagement protrusion that engages with the guide engagement part of the case is formed at the tip of the extension part. The upper surface of the slider is positioned inward of the case than the bottom of the recess formed at the edge so that the opening/closing pin that presses the slider along the edge of the case falls into it, and this engagement 3.5 characterized in that the lower surface of the protrusion is cut out so as not to come into contact with a retaining wall formed on the case and holding a disk-shaped recording medium.
