Abstract
A coupling device of a vehicle seat includes disc-shaped first and second coupling members; at least two lock member; and guide portions that guide the lock members. The guide portions are disposed on sides of each lock member. When the lock members are pushed outwardly in the radial direction so that external teeth of each lock member are engaged with internal of the second coupling member, the lock member is inclined with respect to the corresponding guide portions, and a portion of each side surface of the lock member contacts the side surface of the corresponding guide portion. At this time, one of the lock members is rotated in a rotational direction opposite to a rotational direction in which the other lock member is rotated.
