ABSTRACT:
A first shaft is screwed with a second shaft. The first shaft is secured rotatively to a bearing through a spring and the second shaft is secured slidably to another bearing. A pushing force in a fixed direction is provided to the second shaft through the screwed portion by actuating a spring torque in a rotative direction to the first shaft, whereby a determined tension is given to a chain when a tensioner is slackened in use.
