A clasp member for an accessory that is separably coupled to a coupling subject portion, the clasp member comprising:

• a base portion that is connected to a part of the accessory, wherein the base portion further comprises:
• a base-side coupling portion arranged on one side in a longitudinal direction of the base portion, the one side being opposite to another side on which a connecting part of the base portion is arranged, the connecting part being connected to the part of the accessory,
• a base-side body portion that extends in the longitudinal direction of the base portion,
• base-side support portions that extend from the base-side body portion into a height direction of the base portion;
• and
• a movable portion that is supported by the base-side support portions, and configured to turn relative to the base portion, wherein the turning opens and closes the clasp member for the accessory wherein the movable portion further comprises:
• a movable-side coupling portion,
• a movable-side body portion, wherein the movable-side coupling portion is curved from another end portion of the movable-side body portion to a side on which the base portion is provided,
• lateral cover portions which extend from the movable-side body portion toward the base portion, and at least a part of each of which is superimposed on a corresponding one of the base-side support portions in a side view of the fastening member, wherein the lateral cover portions are coupled to the base-side support portions of the base portion with a coupling shaft portion, and
• an operating portion that extends from one end portion of the movable-side body portion into a direction curved relative to the movable-side body portion, and, under a state in which the movable portion is arranged at a closed position where the movable portion closes a fastening member, an inner peripheral portion or an outer peripheral portion of the movable-side coupling portion and an outer peripheral portion or an inner peripheral portion of the base-side coupling portion are held in contact with or face each other, and a part of the base-side coupling portion and a part of the movable-side coupling portion are superimposed on each other in the longitudinal direction of the base portion, wherein the base-side coupling portion extends from the base-side body portion at a position away from the base-side support portions, and is curved to a side on which the movable portion is provided.
