Abstract
A pressing device for an apparatus for imparting a friction resistance to a rotary shaft driving an engine-output control device directly or indirectly to apply a resistance to an operation of an accelerator. The pressing device is a molded product made of a resinous material whose flexural strength is 50 MPa or higher and flexural modulus of elasticity is 3,300 MPa or higher. When a friction plate is formed compositely with a plate-shaped member to form the pressing device, friction plate is formed of a fluorocarbon resin; and at least one ingredient selected from a whisker whose Mohs hardness is 5 or less, a carbon fiber, and a hard resinous powder.
Claims4
A friction plate for an apparatus in which a friction resistance is imparted to a rotary shaft that drives a vehicle engine-output control device directly or indirectly in response to operation of an accelerator, said friction plate comprising:
- a resinous material consisting of
- a fluorocarbon resin and
- at least one ingredient selected from the group consisting of a whisker whose Mohs hardness is 5 or less, a carbon fiber, and a hard resinous powder.
In a pressing device for an apparatus in which a friction resistance is imparted to a rotary shaft that drives a vehicle engine-output control device directly or indirectly in response to operation of an accelerator, the improvement which comprises a friction plate comprising:
- a friction plate;
- and
- a plate-shaped member that is bonded to the friction plate, wherein said friction plate comprises a resinous material consisting of a fluorocarbon resin, and at least one ingredient selected from the group consisting of a whisker whose Mohs hardness is 5 or less, a carbon fiber, and a hard resinous powder.
