Zusammenfassung:	In a ratchet type chain tensioner, having a toothed rack on its plunger and a pawl cooperable with the rack, a recess is provided between the front end of the rack and the protruding end of the plunger. In the initial stages of operation of the tensioner, the pawl can enter the recess while permitting the plunger to protrude and retract freely within a limited range. Thereafter, when the chain controlled by the tensioner becomes elongated, the pawl cooperates with the rack to limit retraction of the plunger.
