Abstract: A key operation mechanism includes a key cylinder; a locking lever that extends from a side surface of the key cylinder; and an unlocking lever that extends from a side surface of the key cylinder in a direction that is different from the direction in which the locking lever extends. The key operation mechanism further includes a locking pull line that is configured to lock a door and an unlocking pull line that is configured to unlock the door. One end of the locking pull line is attached to the locking lever, and one end of the unlocking pull line is attached to the unlocking lever. When the key cylinder rotates in a locking direction, the locking lever pulls the locking pull line, and, when the key cylinder rotates in an unlocking direction that is opposite the locking direction, the unlocking lever pulls the unlocking pull line.

Abstract: A vehicle has a door including: a canopy section covering a cabin from above; and a side section bulging outward in a vehicle width direction from the canopy section to cover an upper surface of a body lateral section and formed integrally with the canopy section, in which a front end of the door is attached to a body in a freely rotatable manner, and a rear end of the door is vertically movable to open/close the cabin. The vehicle further has a seat section that supports buttocks of an occupant at the time when the occupant gets in/out and is provided on an upper surface of the body lateral section covered with the side section from above.

Abstract: The present disclosure is directed toward simplifying the structure of a door opening and closing mechanism including a plurality of door latches. A body of a vehicle includes a remote control mechanism that operates a left door latch and a right door latch in response to an operation of a left door operation unit or a right door operation unit. The left door operation unit and the right door operation unit are mechanically connected to the remote control mechanism by cables. Similarly, the left door latch and the right door latch are also mechanically connected to the remote control mechanism by plurality of latch cables. The remote control mechanism transmits a force for operating the door latches from one of the left door operation unit and the right door operation unit to all of the door latches via the cables.
