A clutch device comprising: a first ring being one of an inner ring and an outer ring; a second ring being the other of the inner ring and the outer ring; a plurality of first claw members supported by the second ring such that each of the first claw members is oscillatable along a plane perpendicular to an axial direction of the inner ring and the outer ring, each of the first claw members including a first end portion on one side in a circumferential direction of the inner ring and the outer ring; a plurality of second claw members supported by the second ring such that each of the second claw members is oscillatable along the plane, each of the second claw members including a second end portion on the other side in the circumferential direction; a plurality of first biasing members supported by the second ring, and biasing the plurality of first claw members such that the first end portion comes into contact with the first ring: a plurality of second biasing members supported by the second ring, and biasing the plurality of second claw members such that the second end portion comes into contact with the first ring; and a switching mechanism configured to switch a state of the plurality of first claw members and the plurality of second claw members to one of a locked state where the first end portion and the second end portion are in contact with the first ring, a one-way state where the first end portion is in contact with the first ring and the second end portion is separated from the first ring, and a free state where the first end portion and the second end portion are separated from the first ring, wherein the first ring includes a plurality of meshing portions protruding toward a second ring side and arranged in the circumferential direction, each of the plurality of meshing portions has a first surface, a second surface, and a third surface, the first surface faces the other side in the circumferential direction to come into contact with the first end portion in the locked state, the second surface faces the one side in the circumferential direction to come into contact with the second end portion i in the locked state, being characterised in that the third surface faces the second ring side between the first surface and the second surface, and is inclined to approach the second ring as the third surface approaches the first surface, and both an angle formed by the first surface and the third surface and an angle formed by the second surface and the third surface are obtuse angles, and the angle formed by the second surface and the third surface is larger than the angle formed by the first surface and the third surface. a first ring being one of an inner ring and an outer ring;
