SHELLFISH FASTENER, ASSEMBLED SHELLFISH FASTENER, CONTINUOUS SHELLFISH FASTENER, AND ROLL-SHAPED CONTINUOUS SHELLFISH FASTENER

摘要

PROBLEM TO BE SOLVED: To solve the defect of dropping a shellfish engaged to a shellfish-attaching protrusion by the falling down of the shellfish-attaching protrusion of the shellfish fastener. SOLUTION: The shellfish engaged to the shellfish-attaching protrusion is prevented from dropping from a base material and the shellfish-attaching protrusion by providing a falling-off-preventing piece, a dropping-preventing protrusion or a falling-off-preventing part 4 in the shellfish-attaching protrusion 2 protruded from the slender base material to be inserted into a rope or a hole of the shellfish so as not to drop.
