<P>PROBLEM TO BE SOLVED: To provide an emergency mechanism capable of opening and closing a lid by an external force such as human power easily when the motor of a lid opening/closing mechanism to be driven by the motor is in failure. <P>SOLUTION: A link mechanism is driven by a sector gear 13, which is driven by a motor 12 through a pinion 22. The sector gear 13 is fixed to a lever 14 as primer mover, which moves along with rotation of the sector gear 13. The lever 14 is structured so that a first lever member 17 and a second lever member 16 are coupled together by coupling bolt(s), whereby the motor 12 in connection with the link mechanism is disconnected by removing the coupling bolt when the motor 12 is failed and stopped. This allows the lid 6 to be opened manually even when the motor 12 is stopped. At this time, an auxiliary lever 18 keeps identical the moving locus of the lid 6. <P>COPYRIGHT: (C)2008,JPO&INPIT |
