To provide a click mechanism which does not hinder smooth movement of a conveyor with respect to a fixing portion, and enables sure positioning of the conveyor, and to provide a motion guide device provided with the same.
A click mechanism which is arranged between first and second relatively moving structures includes: a positioning projection provided on the first structure; and a positioning member that is provided on the second structure and is engaged with the positioning projection. The positioning member includes: a first positioning piece that is attached so as to be displaceable with respect to the second structure, and has a locking surface on which the positioning projection abuts and a retreating surface inclined in a direction opposite to the locking surface, in accordance with the movement of the second structure with respect to the first structure; a second positioning piece that has the locking surface and the retreating surface, and is attached so as to be displaceable with respect to the second structure independently of the first positioning piece and so as to be adjacent to the first positioning piece, and enables the locking surface to form a positioning groove holding the positioning projection facing the locking surface of the first positioning piece; and biasing means that biases each of the positioning pieces toward the first structure.
