ABSTRACT:
A dog clutch mechanism includes a case, first and second rotatable shafts rotatably disposed coaxially in the case, the second rotatable shaft having an annular groove defined in an outer periphery thereof, a dog piece fixedly mounted on the first rotatable shaft and having first dog teeth confronting an end of the second rotatable shaft, a hub axially slidably mounted on the second rotatable shaft and having second dog teeth meshingly engageable with the first dog teeth, the second dog teeth being movable out of meshing engagement with the first dog teeth under a thrust force in response to relative torque transmission between the first and second rotatable shafts. The hub has guide holes extending radially therethrough toward the second rotatable shaft and a plurality of balls are retained respectively in the guide holes are and engageable in the annular groove. A sleeve is axially slidably disposed on an outer periphery of the hub for engaging the balls and pressing the balls into at least the annular groove.
