A leg pushing power diminution apparatus of a clutch pedal in a vehicle is provided to minimize the leg pushing power transferred to the driver by forming reducers in a cylinder and varying a sectional area of a moved path of hydraulic oil. A leg pushing power diminution apparatus of a clutch pedal in a vehicle comprises a hydraulic piston(21), a cylinder(22), reducers(25), sealing members(23), and a spring(24). The hydraulic piston is connected with a clutch pedal. The hydraulic piston is fitted to the cylinder movably. The reducers are projected on the inner peripheral surfaces of the cylinder to change the inner area of the cylinder. The sealing members are installed on the outer peripheral surfaces of the hydraulic piston. The spring is installed in the cylinder to support the hydraulic piston elastically. The reducers have a small center diameter(d) and a large diameter(D) of both ends thereof.
