Fuel gas filling system

A fuel gas filling system for a vehicle having a fuel gas filler receptacle which allows a fuel gas filler nozzle to be connected thereto, a fuel lid which is operable to be opened or closed for covering the fuel gas filler receptacle, a ground connection section which allows a ground connection line to be connected thereto, and a ground connection lid which is operable to be opened or closed for covering the ground connection section, the fuel gas filling system comprising:

• an opening operation section which is provided in a portion that is covered by the ground connection lid in a closed state, and to which an opening operation for the fuel lid is applied;
• an operation wire, which is provided between the opening operation section and the fuel lid, for making the fuel lid respond to the opening operation applied to the opening operation section;
• and
• a locking device having a movable element connected to the operation wire, a fixed element for supporting the movable element in a manner movable with the operation wire, a lock pin for restraining movement of the movable element by being inserted into the fixed element and the movable element, and an actuator for making the lock pin to be engaged with or disengaged from the fixed element and the movable element,
• wherein the actuator is adapted to make the lock pin to be engaged with the fixed element and the movable element when the vehicle is not in a stationary state.

A fuel gas filling system for a gas-fueled vehicle having a fuel gas filler receptacle which allows a fuel gas filler nozzle to be connected thereto, a fuel filler lid which is operable to be opened or closed for covering the fuel gas filler receptacle, a ground connection section which allows a ground connection line to be connected thereto, and a ground connection lid which is operable to be opened or closed for covering the ground connection section, the fuel gas filling system comprising:

• a ground connection lid opening operation section to which an opening operation for the ground connection lid is applied;
• a fuel filler lid opening operation section which is provided in a portion that is covered by the ground connection lid in a closed state, and to which an opening operation for the fuel filler lid is applied;
• and
• an operating device for making the fuel filler lid respond to the opening operation applied to the fuel filler lid opening operation section;
• and
• a restraining device which is adapted to permit opening of the fuel filler lid by the opening operation applied to the fuel filler lid opening operation section when the gas-fueled vehicle is in a stationary state, and to restrain opening of the fuel filler lid by the opening operation applied to the fuel filler lid opening operation section when the gas-fueled vehicle is not in a stationary state.
