Patent ID: 7703310

Claim:
A door-opening and closing device in a vehicle, said device comprising: a cylinder lock mounted to a door of the vehicle and including a rotor adapted to be turned in response to a key operation, said cylinder lock comprising a cylinder body; a door-locking device mounted to an interior portion of the door of the vehicle, said door-locking device comprising a casing and a door-locking lever shaft which is configured to be turned in response to the turning of said rotor, said casing having a support wall with a support tube portion integrally formed thereon, wherein said door-locking device is configured to be switched over between a locking state and an unlocking state in response to the turning of said door-locking lever shaft; and a power-transmitting mechanism operatively interconnecting said cylinder lock and said door-locking device, said power-transmitting mechanism having a first end accommodated in a first retaining case detachably connected to said cylinder body, said power-transmitting mechanism including: a transmitting wheel relatively non-turnably connected to said rotor in response to the mounting of said first retaining case to said cylinder body, and a flexible turning movement-transmitting member operatively connected at one end thereof to said transmitting wheel so as to perform a twisting motion responsive to the turning of said transmitting wheel, and operatively connected at the other end thereof to said door-locking lever shaft; wherein said power-transmitting mechanism is configured to transmit the turning movement of said rotor to said turning movement-transmitting member via a double angle connection; and wherein said turning movement-transmitting member and said door-locking device are connected to each other through a universal joint accommodated in a second retaining case, said second retaining case affixed on said support wall of said casing of said door-locking device such that said support tube portion of said support wall is substantially circumferentially enclosed, said universal joint comprising: a first joint element partially protruding from and rotatably supported in said support tube portion, and a second joint element for fixedly receiving said turning movement-transmitting member at the other end thereof, said second joint element rotatably supported in said second retaining case, wherein said first joint element and said second joint element each have engaging portions fitted with each other such that said first joint element and said second joint element are concurrently rotatable when disposed non-coaxially with respect to one another.
