    摘要: A centrifugal clutch comprises a clutch drum (4) loosely rotated relative to a rotary drive shaft (21) and provided with large inner diameter portions (43) and engaging protuberances (44) inwardly projecting from the large inner diameter portions (43); a clutch body (5) loosely fitted within the clutch drum (4), admitting insertion and fitting of the rotary drive shaft (21) to be driven by the rotary drive shaft (21), and provided with a retaining hole (53) opening radially from the centre thereof toward the inner wall of the clutch drum (4); and an engaging permanent magnet (6) loosely movably retained in the retaining hole (53) of the clutch body. When the clutch body (5) is in a standstill state, the engaging permanent magnet (6) exerts its magnetic attraction onto the rotary drive shaft (21) and thereby is accommodated within the retaining hole (53). When the clutch body (5) continues its rotation, centrifugal force is generated. The centrifugal force allows the engaging permanent magnet (6) to protrude from the retaining hole (53), come into contact with the slide on the inner wall of the clutch drum (4) and engage with one of the engaging protuberances (44) of the clutch drum (4).
