Abstract

Official abstract text for this publication.

In a tensioner having a housing and a plunger protruding in an advancing direction from a plunger-accommodating hole formed in the housing. The plunger has a cylindrical outer wall for sliding contact with the wall of the plunger-accommodating hole, and a tapered the rear end wall. A small clearance between the cylindrical outer wall of the plunger and the wall of the plunger-accommodating hole allows the plunger to become inclined by a small amount, which increases as the plunger advances. The angle of the taper at a boundary where the end wall meets the cylindrical outer wall is substantially equal to the maximum inclination of the plunger when the plunger is in its fully advanced condition.
