Claim:
A dog clutch comprising: a first dog clutch member coupled with a rotation transmitting member rotatably mounted on a power transmission shaft, with a relative rotation clearance (θ); a second dog clutch member slidably mounted on the power transmission shaft to be engageable/disengageable with/from the first dog clutch member; a first pair of spring holding recesses whose respective open surfaces are opposed to each other are formed in opposed surfaces of the first dog clutch member and the rotation transmitting member; and a first damper spring disposed in the first pair of spring holding recesses so as to be interposed between the rotation transmitting member and the first dog clutch member for being elastically deformable within a range of the relative rotation clearance (θ) by a torque generated between the rotation transmitting member and the first dog clutch member; wherein gear teeth-like first dog teeth and second dog teeth, which are engaged/disengaged with/from each other by an axial displacement of the second dog clutch member, are formed in the first dog clutch member and the second dog clutch member, respectively, and a chamfer is made in each end portion of the respective first dog teeth and each end portion of the respective second dog teeth, which are opposed to each other, so as to guide the second dog teeth to a position to engage with the first dog teeth.
