There are a couple possibilities. It could be that one of the motor mounts is broken, but that's doubtful. Sometimes a vehicle will resonate with the tires if one is out of balance slightly. The feeling can come through the seat for rear tires or through the steering wheel for front tires. It's possible that your just resonates through the pedal or that's just where you feel it. Have the tire balance checked as a good place to start. Beyond that, check for a bent "half-shaft", that's the drive-shaft between the transaxle and the front wheels. Lift the wheels, put the vehicle in neutral gear and spin the wheel by hand while you watch the half-shaft to see if it's straight. Beyond that, I don't have many ideas.
The clutch pedal pivots at the top, Unlike the gas pedal where the pivot point is at the middle.
On the undwerside of the dash attached to the brake pedal.
There can be many reasons so to why the pedal vibrates. You may have bad motor mounts, or the throttle cable mount can be loose. There is no sping located at the pedal, instread it is on the throttle body. Make sure everything is bolted down correctly and tightly
The sustain pedal lifts the dampers off of the strings, allowing them to vibrate until the pedal is released.
The clutch pedal cannot be adjusted
One of the main causes of feeling a vibration in the gas pedal is engine vibration. The vibration from the engine causes the accelerator cable or linkage to vibrate and the vibration can be felt in the gas pedal. Check with a mechanic to be sure.
Is it an automatic or manual transmission? If its a manual trans its under the clutch pedal.

Not on the clutch itself but on the clutch pedal there is one for starting.
