A working vehicle comprising: a vehicle body; a cabin mounted on the vehicle body; a pedal shaft provided in the cabin; a clutch pedal pivotally supported by the pedal shaft; a clutch provided on the vehicle body; a clutch operation member to engage and disengage the clutch; a linkage member having first and second ends, the first end of the linkage member being connected to the clutch operation member; an interlocking linkage mechanism to interlock the clutch pedal with the second end of the linkage member so that vibrations of the cabin are suppressed from transmitting to the clutch; and a support frame attached to the vehicle body, characterized in that the clutch pedal includes a pedal arm extending lengthwise in a vertical direction and having an upper portion pivotally supported by the pedal shaft, a pedaling member fixed to a lower portion of the pedal arm, and a connecting stay fixed to the pedal arm, the interlocking linkage mechanism includes an interlocking linkage having a rear end connected to the connecting stay below the pedal shaft, the interlocking linkage extending downwardly forward from the connecting stay, and an intermediate linkage to interlock the linkage member with a front end of the interlocking linkage and, the intermediate linkage includes a linkage support shaft attached to the support frame, a pivoting boss provided on the outer periphery of the linkage support shaft rotatably around the axial center of the linkage support shaft, a first linkage stay fixed to an upper portion of the pivoting boss such that the first linkage stay protrudes upward and connecting the front end of the interlocking linkage, and a second linkage stay fixed to a lower portion of the pivoting boss such that the second linkage stay protrudes downward and connecting the second end of the linkage member. a vehicle body; a cabin mounted on the vehicle body; a pedal shaft provided in the cabin; a clutch pedal pivotally supported by the pedal shaft; a clutch provided on the vehicle body; a clutch operation member to engage and disengage the clutch; a linkage member having first and second ends, the first end of the linkage member being connected to the clutch operation member; an interlocking linkage mechanism to interlock the clutch pedal with the second end of the linkage member so that vibrations of the cabin are suppressed from transmitting to the clutch; and a support frame attached to the vehicle body, characterized in that the clutch pedal includes a pedal arm extending lengthwise in a vertical direction and having an upper portion pivotally supported by the pedal shaft, a pedaling member fixed to a lower portion of the pedal arm, and a connecting stay fixed to the pedal arm, a pedal arm extending lengthwise in a vertical direction and having an upper portion pivotally supported by the pedal shaft, a pedaling member fixed to a lower portion of the pedal arm, and a connecting stay fixed to the pedal arm, the interlocking linkage mechanism includes an interlocking linkage having a rear end connected to the connecting stay below the pedal shaft, the interlocking linkage extending downwardly forward from the connecting stay, and an intermediate linkage to interlock the linkage member with a front end of the interlocking linkage and, an interlocking linkage having a rear end connected to the connecting stay below the pedal shaft, the interlocking linkage extending downwardly forward from the connecting stay, and an intermediate linkage to interlock the linkage member with a front end of the interlocking linkage and, the intermediate linkage includes a linkage support shaft attached to the support frame, a pivoting boss provided on the outer periphery of the linkage support shaft rotatably around the axial center of the linkage support shaft, a first linkage stay fixed to an upper portion of the pivoting boss such that the first linkage stay protrudes upward and connecting the front end of the interlocking linkage, and a second linkage stay fixed to a lower portion of the pivoting boss such that the second linkage stay protrudes downward and connecting the second end of the linkage member. a linkage support shaft attached to the support frame, a pivoting boss provided on the outer periphery of the linkage support shaft rotatably around the axial center of the linkage support shaft, a first linkage stay fixed to an upper portion of the pivoting boss such that the first linkage stay protrudes upward and connecting the front end of the interlocking linkage, and a second linkage stay fixed to a lower portion of the pivoting boss such that the second linkage stay protrudes downward and connecting the second end of the linkage member.
