Vehicle control apparatus

Abstract

A vehicle equipped with a motor-operated mechanism that contains a clutch. The pushing member of the clutch is energized against a friction plane by an energizing mechanism and transfers power from a driving power source when it touches the friction plane. The location of the pushing member can be retained even when power is shut off. This structure prevents promotion of deterioration of a diaphragm spring in a state in which the clutch remains disengaged when the key switch is turned off.
