drive shaft (21) is made of a magnetic material. As noted in
column 2, lines 20-30,
"[w]hen the clutch body is not driven the
permanent magnet is moved toward the rotary drive
shaft due to the magnetic attraction therebetween
and is accommodated within the retaining hole. When
the clutch body is being driven at a certain speed,
the permanent magnet is released from the rotary
drive shaft by the centrifugal force of the clutch
body, projects toward the inner wall of the clutch
drum and is engaged with an engaging protuberance
provided in the clutch drum with the result that the
rotation of the clutch body is transmitted to the
clutch drum."
As the examiner has recognized (final rejection, page 4),
