Abstract
In one embodiment, there is provided a tensioner for an endless drive member. The tensioner comprises a base that is mountable to a stationary structure, the base defining a tensioner arm pivot axis, a tensioner arm that is mounted to the base and is pivotable about the tensioner arm pivot axis, a pulley rotatably connected to the tensioner arm for rotation about a pulley axis that is spaced from the tensioner arm pivot axis, and a tensioner arm biasing member positioned to urge the tensioner arm in a free arm direction. The tensioner arm biasing member includes a closed-cell foam member.

A tensioner for an endless drive member, comprising:
- a base that is mountable to a stationary structure, wherein the base defines a tensioner arm pivot axis;
- a tensioner arm that is mounted to the base and is pivotable about the tensioner arm pivot axis;
- a pulley rotatably connected to the tensioner arm for rotation about a pulley axis that is spaced from the tensioner arm pivot axis;
- and
- a tensioner arm biasing member positioned to urge the tensioner arm in a free arm direction, wherein the tensioner arm biasing member includes a closed-cell foam member.
A tensioner as claimed in claim, wherein the closed-cell foam member exerts a damping force during compression.
