Abstract:
A lever 40 is supported by a lever supporting portion 41. The lever 40 is urged by a spring 45. A friction producing member 47 is in contact with a pivot restricting member 46 which is interlocked with the lever 40 to produce a frictional force in a direction opposite to the direction in which the lever 40 pivots. Such a configuration allows a pedal apparatus to exhibit hysteresis in characteristics of the amount of depression of the lever 40 and reaction force.
