ABSTRACT:
In a clutch of the type including a fork inserting hole formed at a certain position of a side wall of a clutch housing, so as to insert and install a clutch release fork from an outer side of the clutch housing, a clutch ventilation structure comprises a ventilation duct which has a L-shaped ventilation passage therein and which is mounted to the fork inserting hole. An inner end of the ventilation passage is open into the clutch housing, and an outer end of the ventilation passage is open to the atmosphere. With this arrangement, ventilation of the inside area of the clutch housing may be smoothly carried out by effectively utilizing the fork inserting hole without closing the hole with a blind plug, thereby improving a cooling effect of the clutch.
