FIELD: mechanical engineering.
SUBSTANCE: chain tensioner is comprised of a housing, in the hole of which a pusher with a support section is installed, and at least one section of the housing surface is made cylindrical. The hole in which the pusher is installed is displaced relative to the longitudinal geometrical axis of the cylindrical section of the body, and the pusher is equipped with a locking device from fixing its rotation around the geometric longitudinal axis of the hole in which it is installed. According to the invention, the median longitudinal axis of the support section of the pusher is located in the displacement area relative to the geometric axis of the cylindrical section of the body, while the maximum displacement of the said axis is less than the distance of the geometric longitudinal axis of the pusher from the geometric axis of the cylindrical section of the body.
EFFECT: increased accuracy of the device operation, as well as increased reliability.
