  2. Description of the Related Art Conventionally, for example, in a racing straddle-type vehicle or the like, a system (clutchless shift system) that detects a shift operation from a driver and changes a gear position without a clutch connection / disconnection operation has been employed. A straddle-type vehicle employing such a system detects a shift operation (shift-up, shift-down, etc.) by a driver, and requires a clutch engagement / disengagement operation based on information on the detected shift operation. The gear position can be changed without any change.

  Here, the shift operation by the driver is detected by a shift operation detection device connected to the shift pedal. The shift operation detection device is desired to accurately detect the shift operation without impairing the shift operability by the driver.

  On the other hand, there has been proposed a shift rod device having a rod whose one end is connected to a shift pedal, a spring (elastic member) for applying a reaction force (biasing force) to the rod, and a stroke sensor (for example, a patent) Reference 1).
