Abstract:
1. A friction clutch configured to be engaged/disengaged by an operation of a clutch operator, comprising: a driving-side rotator having a first plate; a driven-side rotator having a second plate facing the first plate; a pressure plate movable in a predetermined direction to bring the first plate and the second plate into contact with each other when the clutch operator is operated; a cam face formed on a side of the pressure plate opposite to the first plate side and the second plate side; an opposing member having an opposing face that faces the cam face; a centrifugal weight arranged between the cam face and the opposing face; and an urging member for urging the centrifugal weight toward the cam face side via the opposing member, wherein an angular velocity ω represented by the following equation increases when a parameter R increases and the angular velocity ω decreases when the parameter R decreases, ω
