A vehicle approach alert device (40;140;250;340) for a saddle-ridden electric vehicle (10;101;201;301) that is attached to a vehicle body of a saddle-ridden electric vehicle having an electric motor (41;103;332) included in a power engine (41;M;332), and that is provided with a sound emitter (48,48';160,160';251;341,341') that emits an alert sound to a surrounding area for notifying the surrounding area of approach of the saddle-ridden electric vehicle, wherein: sound emission of the sound emitter is controlled according to a traveling status of the vehicle; and the sound emitter is arranged so that a direction (48a;48a';160a,160a';251a;341a,341a') of the sound emission is oriented diagonally downward and forward of the saddle-ridden electric vehicle, and the sound emitter raises a frequency of the alert sound in proportion to an increase in a rotation speed of the electric motor, and an increase rate of this alert sound frequency is set so as to be lower than an increase rate of the rotation speed of the electric motor, and the alert sound includes at least, a first sound serving as a reference sound, a second sound having a frequency higher than the first sound, and a third sound having a frequency higher than the second sound, and a ratio of 1 subtracted from a ratio of the frequency of the second sound with respect to the frequency of the first sound is set to be greater than a ratio of the frequency of the second sound with respect to the frequency of the first sound, subtracted from a ratio of a frequency of the third sound with respect to the frequency of the first sound; wherein: the saddle-ridden electric vehicle is provided with a front cover (43A;121A;207A;324A) that covers the periphery of a head pipe (12;112;236;312) of a vehicle body frame (11;111;234;305); and the saddle-ridden electric vehicle is further provided with a vehicle body frame member (21;305f) that extends diagonally backward and downward of this saddle-ridden electric vehicle, from the head pipe; on the head pipe there is steerably supported a front fork (15;106;202;313) that extends diagonally forward and downward and that suspends a front wheel (105;WF); and the sound emitter is arranged on an inner side of the front cover and in front of the vehicle body frame member and at the rear of the front fork when this saddle-ridden electric vehicle is seen from a side. sound emission of the sound emitter is controlled according to a traveling status of the vehicle; and the sound emitter is arranged so that a direction (48a;48a';160a,160a';251a;341a,341a') of the sound emission is oriented diagonally downward and forward of the saddle-ridden electric vehicle, and the sound emitter raises a frequency of the alert sound in proportion to an increase in a rotation speed of the electric motor, and an increase rate of this alert sound frequency is set so as to be lower than an increase rate of the rotation speed of the electric motor, and the alert sound includes at least, a first sound serving as a reference sound, a second sound having a frequency higher than the first sound, and a third sound having a frequency higher than the second sound, and a ratio of 1 subtracted from a ratio of the frequency of the second sound with respect to the frequency of the first sound is set to be greater than a ratio of the frequency of the second sound with respect to the frequency of the first sound, subtracted from a ratio of a frequency of the third sound with respect to the frequency of the first sound; wherein: the saddle-ridden electric vehicle is provided with a front cover (43A;121A;207A;324A) that covers the periphery of a head pipe (12;112;236;312) of a vehicle body frame (11;111;234;305); and the saddle-ridden electric vehicle is further provided with a vehicle body frame member (21;305f) that extends diagonally backward and downward of this saddle-ridden electric vehicle, from the head pipe; the saddle-ridden electric vehicle is provided with a front cover (43A;121A;207A;324A) that covers the periphery of a head pipe (12;112;236;312) of a vehicle body frame (11;111;234;305); and the saddle-ridden electric vehicle is further provided with a vehicle body frame member (21;305f) that extends diagonally backward and downward of this saddle-ridden electric vehicle, from the head pipe; on the head pipe there is steerably supported a front fork (15;106;202;313) that extends diagonally forward and downward and that suspends a front wheel (105;WF); and the sound emitter is arranged on an inner side of the front cover and in front of the vehicle body frame member and at the rear of the front fork when this saddle-ridden electric vehicle is seen from a side.
