Shifting-operation detection unit

A shifting-operation detection unit comprising:

• a first detection unit provided on a link unit of a shift mechanism, which couples a transmission and a shift pedal both being mounted on a saddle-ride type vehicle to each other, to detect a shift-up operation of the transmission in accordance with an operation of the shift pedal and include a first switch, the first detection unit being provided with a first resistor connected in series to the first switch and a second resistor connected in parallel to the first switch and the first resistor;
• and
• a second detection unit provided on the link unit to detect a shift-down operation of the transmission in accordance with an operation of the shift pedal and include a second switch, the second detection unit being provided with a third resistor connected in series to the second switch and a fourth resistor connected in parallel to the second switch and the third resistor,
• wherein the first detection unit and the second detection unit are connected in series to be connected to correspond to a power supply terminal and a ground terminal of an external device and apply a divided voltage of a voltage of the power supply terminal to the external device via an electric wire, the divided voltage having voltage values corresponding to the shift-up operation and the shift-down operation, respectively.
