A slider provided for supporting the shutter, is disposed on the cartridge body and is capable of sliding and is resiliently restored by a spring. The slider is engaged slidably with a groove or protrusion formed along a slide of the cartridge body by way of an engagement part. A portion of an engaging structure between the engagement part of the slider and the cartridge body makes a line contact between a protrusion or protrusion of the engagement part of the slider and the groove or protrusion of the cartridge body.
