Abstract
A dog clutch includes: a first rotational member; a second rotational member; a clutch member; and a pressing mechanism. The clutch member includes a meshing portion meshing with the second rotational member, an engageable portion circumferentially engaging with an engaged portion provided in the first rotational member, and a cam surface configured to generate a cam thrust in a direction of a rotation axis by a relative rotation with respect to the first rotational member. When the clutch member moves, a depth of meshing with the second rotational member is deepened by the cam thrust, and then the engageable portion engages with the engaged portion, so that the clutch member receives a torque from the first rotational member.
