摘要： A blade-type tensioner (1) for applying tension to a chain comprising a base (4), an arcuately shaped blade shoe (2) having a chain sliding face (2a), a spring (3) provided on a back side of the blade shoe, and a guide member. The blade shoe has a proximal end portion (20) and a distal end portion (21), where the proximal end portion is swingably supported on the base, and the distal end portion is slidably supported on a slide plate (41) of the base. The slide plate is arcuately shaped to form a concavely arcuate arc face (41a) on an opposite side of the distal end portion of the blade shoe, and the distal end portion of the blade shoe has a convexly arcuate arc face (21c) corresponding to the concavely arcuate arc face of the slide plate. The distal end portion of the blade shoe is guided by a self-aligning action of the concavely arcuate arc face of the slide plate in such a way that the distal end portion is centrally positioned in a lateral direction on the slide plate. The guide member (6) comprises a pair of guide portions (6'a) formed integrally on opposite side edges of the distal end portion of the blade shoe, and hang below opposite side ends of the slide plate.
