Actuation of the pedal member is thus transmitted, via the push rod, to the master cylinder, which in turn actuates the clutch.
  • the bracket was configured to hold the pedal member within a range of positions in which the push rod could be fastened to the pedal member.
  • the bracket has been simplified and may no longer hold the pedal member within such range. Therefore, in order to fasten the pedal member to the push rod, an operator must bring the pedal member and the push rod in respective positions in which they can be fastened to each other, hold the pedal member and the push rod in such positions, and operate fastening means.

Then, the operator, or another operator, has both hands free to adjust the position of the push rod and fasten the push rod to the pedal member. Therefore, installation of the control device is greatly simplified.
