Claim 9:
10. A damper structure comprising:
a biasing part biasing, in an opening direction, a lid part arranged rotatably on a main body about a shaft in an openable and closable manner; and
a plurality of regulators each generating resistance against a biasing force in the opening direction at different timing during an opening motion of the lid part,
the regulators comprising a first regulator and a second regulator coupled in a shaft direction of the first regulator,
the damper structure further comprising a coupling part placed covering a peripheral face of the first regulator and coupling the first regulator and the second regulator with each other in the shaft direction,
the first regulator having a base part fixed to the main body and a rotating part rotating about the shaft with respect to the base part,
the second regulator having a base part fixed to the coupling part and a rotating part rotating about the shaft with respect to the base part,
the coupling part being fixed to the main body, wherein
the first regulator has a protruding part protruding radially outward from a peripheral face of the rotating part,
the second regulator has a protruding part protruding radially outward from a peripheral face of the rotating part,
the lid part has a first recessed part with which the protruding part of the first regulator is engaged and a second recessed part with which the protruding part of the second regulator is engaged,
the first regulator, during an opening operation of the lid part, does not reduce an opening speed of the lid part in a state in which the protruding part of the first regulator is positioned at a circumferentially intermediate part of the first recessed part and reduces the opening speed of the lid part in a state in which the protruding part of the first regulator is in contact with a circumferential end part of the first recessed part, and
the second regulator, during the opening operation of the lid part, does not reduce the opening speed of the lid part in a state in which the protruding part of the second regulator is positioned at a circumferentially intermediate part of the second recessed part and reduces the opening speed of the lid part in a state in which the protruding part of the second regulator is in contact with a circumferential end part of the second recessed part.
