Abstract:
1. A door opening and closing device for a vehicle comprising: a door lock device mounted on a door and comprising a latch mechanism that can switch between a locked state in which opening of the door is disabled and an unlocked state in which opening of the door is enabled and a lock/unlock switching mechanism having a key operating force input member that pivots so as to switch between the locked state and the unlocked state of the latch mechanism; a cylinder lock mounted on the door and having a rotor that pivots in response to a key operation; and a pivot rod having one end part linked to the rotor side so as to transmit to the key operating force input member side a pivoting force of the rotor pivoting in response to a key operation of the cylinder lock, wherein the door opening and closing device comprises pivoting force transmission means formed by housing a driven-side pivot member, a drive-side pivot member, and a transmission member within an extension case, the driven-side pivot member being coaxially and detachably linked to the key operating force input member in a relatively non-pivotable manner, the drive-side pivot member, being disposed at a position spaced from the driven-side pivot member, and being coaxially and detachably linked to the other end part of the pivot rod in a relatively non-pivotable manner, the transmission member being provided between the drive-side and driven-side pivot members so as to transmit a pivoting force from the drive-side pivot member to the driven-side pivot member, the extension case pivotably supporting the driven-side pivot member and the drive-side pivot member, and the extension case being detachably mounted on a casing of the door lock device so as to extend from the casing.
