Claim:
1. A selectable one-way clutch, comprising: a first annular plate and a second annular plate opposed to each other while being allowed to rotate relatively with each other; a first depression formed on an outer circumferential side of the first annular plate to be opposed to the second annular plate; a pawl held in the first depression in such a manner that a leading end thereof is allowed to reciprocate toward and away from the second annular plate; a second depression formed on an outer circumferential side of the second annular plate to be opposed to the first annular plate, into which the leading end of the pawl enters to be engaged therewith; an intermediate plate disposed between the first annular plate and the second annular plate, and configured to rotate relative to the first annular plate and the second annular plate; and an aperture formed on the intermediate plate, that is selectively overlapped with the first depression to selectively allow the pawl to project toward the second depression therethrough; wherein the pawl comprises a strut that is pushed toward the second depression through the aperture, a stopper plate protruding laterally from a rear end side of the strut, and a first inclined face formed on the stopper plate in such a manner to incline downwardly from the rear end side toward the leading end side of the strut; wherein the intermediate plate comprises a side plate formed along each long side of the aperture to protrude toward the first annular plate; and wherein the side plate comprises a second inclined face that is inclined in such a manner to be withdrawn from the first inclined face when the aperture is overlapped with the first depression to allow the strut to enter into the second depression, and to be brought into contact with the first inclined face when the aperture is partially displaced from the first depression to push the strut integral with the stopper plate into the first depression.
