An engine control apparatus in which, when it is detected by a starter switch that a starter has changed-over from a drive state into a non-drive state, an ECU predicts a time period in which an engine is completely stopped, on the basis of a revolution speed of the engine at that time, so as to turn OFF an output of a starting motor relay for the predicted period. A master cylinder is connected to the power piston to generate a master cylinder pressure to thereby output a regulated control valve output pressure. Detachable end plates are secured to each of the opposed ends. The cover can include gripping tabs for facilitating the separation of the cover from the base and permit container venting. The damping springs are compressed against the fixed contacts when the hit contact comes into contact with the barrier. The diversity receiving apparatus includes a first signal adjusting unit for amplifying a first signal received by a first antenna and for phase-shifting, a second signal adjusting unit for amplifying a second signal received by the second antenna and for phase-shifting, and a controller.
