PROBLEM TO BE SOLVED: To obtain a shutter device in which an opening can be closed surely by a sliding shutter and by which a bulk case can be attached to, and removed from, a prescribed position after its confirmation by a method wherein the tip part of the sliding shuter is formed so as to be sharpened toward an advance direction in which the sliding shutter is closed. SOLUTION: A sliding shutter 3 at a bulk case 1 is formed so as to be a state that the right and left faces and the upper and lower faces of its tip part 3a are directed gradually toward the inside as they advance to the tip, i.e., that they are sharpened toward its advance direction in which the sliding shutter 3 is closed. Consequently, when an opening 5 is closed by the sliding shutter 3 and even when a component is clogged at the front of the tip part 3a, the shutter advances while it pushes the component so as to be inserted into, and coupled to, a coupling groove 9 finally, and the opening 5 can be closed completely. |
