• a first holding member that is supported by the first arm and is located in a region of the first arm that faces the second arm in the closed position;
• a second holding member that is supported by the second arm and is located in a region of the second arm that faces the first holding member on the first arm in the closed position;
• a plurality of protrusions being poor thermal conductors, which are supported by the first arm and protrude outward in a region of the first arm that does not face the second arm in the closed position;
• and
• a surface member located between the protrusions on the first arm,
• wherein the surface member and at least one of the first holding member and the second holding member are good thermal conductors and are capable of generating heat based on heat from a heat source.
