Upon receipt of a direction indication control signal s , a sounding-body driving circuit generates a driving signal s for generating a flashing operation sound which is an artificial striking sound similar to a striking sound of a mechanical relay. The driving signal s is output to a speaker via an amplifier , and the flashing operation sound is outputted from the speaker , thereby obtaining the flashing operation sound which does not sound unusual to the driver. The sounding-body driving circuit enables a plurality of rectangular wave signals having the same amplitude and different frequencies to be synthesized in sequence of time by first and second synthetic signal generating circuits A and B to thus generate first and second synthetic signals s and s as artificial striking sounds.
