Electric motor

A seathas a seat cushionand a seat backand is mounted on a vehicle such as a car. A reclining mechanismcapable of adjusting the tilt angle of the seat backis provided between the seat cushionand the seat back. The reclining mechanismhas a seat driving deviceprovided with an electric motorand a speed reduction mechanism. The speed reduction mechanismhas a worm shaftconnected to a motor shaftof the motorand a worm wheelmeshed with a wormof the worm shaft. The wormis a multi-thread worm having two or more threads.

Seat driving device

A speed reducer () including a gear case () is attached in an electric motor, and a pinion is provided to an output shaft () protruding from the gear case (). A base portion () protruding in a diametrical direction is provided to the gear case () and a support shaft is mounted to the base portion (). A sector gear () is fixed to a base end of a lift arm (), and the sector gear () is swingably supported by the support shaft and meshed with the pinion. In addition, a groove portion () in a circular arc shape is provided to the sector gear (), and a gear cover () is fixed to the gear case () by a bolt () penetrating the groove portion () and a bolt () disposed on an outer periphery side than the sector gear (), and the gear cover () covers a mesh portion of the pinion and the sector gear () and presses the sector gear () toward the gear case ().

Automatic opening and closing apparatus for vehicle

An automatic opening and closing device including: a trunk lid; a drive unit which generates drive force for operating the opening and closing member; a hinge arm which is mounted between a rear fender and wheel house inner panel and the trunk lid; and a first link and a second link which transmit the drive force of the drive unit to the trunk lid. The drive unit is fitted to an edge portion of a trunk room aperture portion, and the first and second link are provided so as to straddle the hinge arm.

Automatic opening and closing device

Provided is a power actuator system for actuating a closure member () such as a trunk lid which is compact in size and has a minimized protrusion. A first link () is connected to an output shaft of a powered actuator (), and a free end of the first link is connected to an end of a second link (). The other end of the second link is pivotally connected to a hinge arm () which is fixedly attached to a closure member and pivotally supports the closure member to a fixed part such as a vehicle body. The first link is adapted to extend substantially from the output shaft towards the closure member as the first link swing around the output shaft, and the second link extends substantially perpendicularly with respect to the center line.
