  • Patent number: 8845001
    Abstract: A push lifter is provided with a push-push mechanism. When a charger lid is positioned in a closed position to close a battery charging opening, the push-push mechanism holds a push rod in a standby state. When the charger lid, which is positioned in the closed position, is pressed so that the standby state of the push rod is cancelled, the push-push mechanism pushes the push rod with the urging force of a coil spring so that the charger lid opens. An illumination lamp turns off when a switch portion turns off due to the standby state of the push rod, and the lamp turns on when the switch portion turns on due to the standby state of the push rod being cancelled.
