Abstract: A door drive device is disclosed, which comprises a guide rail for defining in the body of the vehicle a way along which the slide door moves; first and second pulleys arranged at spaced positions of the vehicle body; an electric drive unit for driving the first pulley; an endless belt put around the first and second pulleys with a slack thereof; a bracket for connecting a portion of the endless belt to the door; and a tensioning device for tensioning the endless belt. Due to provision of the slack of the belt, various advantages are obtained particularly when the door drive device of the invention is used in combination with other door controllers.

Abstract: A drive apparatus of a roof structure for a vehicle comprises a drive gear rotatably supported by a casing of the apparatus; a first gear for transmitting the power from the drive gear to a drive section for opening and closing a lid disposed in the roof structure; a rotary member having a control section for switching a switch for detecting the position of the lid; and a second gear for transmitting the power from the drive gear to the rotary member. The drive apparatus has a control device for controlling a drive motor for driving the roof structure.

Abstract: An inside handle device for an automotive vehicle door in which a compression spring (18) for urging a handle (8) to its closed position is provided in an air gap (17a) in a bracket member (7) pivotally securing the handle (8) to reduce the size of the entire device and to simplify the assembly. The handle (8) is pivotally secured to the bracket member (7) which is secured to a door panel (15), and is connected via a connecting rod (3) to a door locking mechanism.

Abstract: In a vehicle glass raising and lowering apparatus, a frame is provided comprising a pair of spaced guide rails held in a parallel disposition by a pair of transverse brackets. A carrier plate is slidably mounted on each guide rail for supporting a vehicle window glass secured thereto. Cable drive apparatus is connected to at least one of the carrier plates providing power reciprocation for the window glass. The apparatus being capable of insertion through a relatively narrow slot in a vehicle door.

Abstract: A reduction gear mechanism comprising a worm and a worm wheel which mechanism includes a magnet clutch wherein a coil is disposed in one side of the worm wheel which serves as a rotor, while an armature is disposed in the other side of the same. Upon energization of the coil, the mechanism acts as a normal reduction gear whereas, upon deenergization, an output power shaft of the clutch can be rotated freely or independently. Since the incorporation of the magnet clutch results in no substantial increase of the size of the reduction gear mechanism, the mechanism can be advantageously installed where a space for installation is restricted, such as a door of an automobile.

Abstract: By providing two separate units for actively opening and closing a door of an automobile, safe and reliable door opening and closing operation may be achieved. The first unit is operated to open the door in a normal way and closes the door to its not fully latched state while the second unit completes the door closure operation by closing it to the fully latched state, thereby reducing the unfavorable influences arising from the impact which is otherwise unavoidable for complete closure of the door.

Abstract: An inside-handle arrangement for the vehicle door assembly has a member, for pivotably securing a handle onto a door inner panel, with a circumferential edge capable of air-tight engagement with a door trim. Further, the member is adapted to close in an air-tight fashion an opening through which the handle is received using a portion of the handle for providing the air-blocking arrangement.
