  • Patent number: 9694782
    Abstract: The present application discloses a control device for an automatic transmission mounted in a vehicle including idling stop means for automatically stopping an engine when a predetermined stop condition is satisfied, and restarting the engine when a predetermined restart condition is satisfied in an engine automatically stopped state. The control device for the automatic transmission includes a first friction element and a second friction element fastened in a starting stage of the automatic transmission; and hydraulic-pressure controlling means for controlling hydraulic pressure for fastening the first and second friction elements. The first friction element includes a return spring that urges a piston of the first friction element to a release side. The second friction element includes a friction plate, a pressing piston that presses the friction plate, and a clearance adjustment piston that supports the pressing piston so as to allow relative movement of the pressing piston.

  • Patent number: 6152521
    Abstract: A front body structure for a vehicle has a pair of front side frames of a boxed-type which extend in a lengthwise direction from the front to the back of the vehicle at opposite sides of the front body. The front side frame has a closed rectangular cross section which has an approximately constant height over the length and has a height-to-width ratio gradually decreasing toward a ratio of 1 (one) as the front frame comes closer to the forward end thereof.
