ABSTRACT:
A friction mechanism for control apparatuses is for use in a control apparatus provided with a discoidal accelerator wheel supported in a freely rotating manner in a housing member and for applying frictional resistance to the said accelerator wheel. The said friction mechanism consists of a friction block supported in the housing member so as to mate with the accelerator wheel in the vicinity of its rim, a pressing member for pressing the friction block supported in the housing member in a direction axial to the accelerator wheel, and a conversion mechanism for converting the pressing force of the said pressing member (a chief constituent of which is the inclined surface formed on the friction block) from the said axial direction to a direction inclined toward the center of the accelerator wheel.
