Abstract: An advancement and the advancing state of a tension rod which maintains a belt or a chain in a tension state is maintained by a coil spring. The coil spring deflects against an excess of opposite force from the belt or the chain to go back the tension rod and prevents the excess tension of the belt or the chain.The coil spring having a non-linear characteristic attached within the casing so as to be a range of the use including a changing point of a load deflection characteristic changes the number of active turns of the coil spring at the time of the resonance of the belt or the chain with changing point as the boarder.The above resonance decreases according to the change of the natural frequency of the vibration of the coil spring.The advancement of the tension rod can also be performed by the coil spring formed by the stranded wires.

Abstract: A tensioner is provided with a female screw member for the tension adjustment of a belt or a chain screwed with a male screw provided a rotation force by a spring and a bearing in which the female screw member is inserted and constrains the rotation of the female screw member.In this tensioner, an outer form of the female screw member is formed so as to correspond to a bearing hole of the bearing. By this, an approximately whole length of the female screw member is able to slide through the bearing hole, and the stroke length of the female member can be secured sufficiently even if the size of the device in a tension controlling direction is shortened.

Abstract: A tension providing mechanism including two shafts, one having an external screw and the other having an internal screw, the shafts being connected by engaging the screwed portions with each other. One of the shafts is supported for axial translation without rotation, and the other shaft is supported for rotation and is restrained from axial sliding. The rotatable shaft includes a torsion spring for applying spring torque in a direction to cause the other shaft to extend in an axial direction against a member, such as a drive chain, in order to increase the tension thereof. A locking mechanism is provided for constraining movement of the rotatable shaft, the locking mechanism being in the form of a lever having one end removably engaged with a split groove provided in the end of the shaft, the other end of the locking mechanism being latched to a projection formed on the case in which the tension providing mechanism is housed.

Abstract: A locking mechanism for use in a tension providing device. The tension providing device has a first shaft with a threaded end portion disposed within the interior of a cylindrical casing and a second end with a slit groove formed therein. A second shaft of the tension providing device has a threaded end engaged with the threaded end of the first shaft and an end protruding from the casing for providing tension. Rotation of the first shaft by a spring results in translation of the second shaft with respect to the casing. The locking mechanism includes a stopper pin removably secured in a lid of the casing at a position spaced from the axis of the first shaft. The pin is movable into engagement with the slit groove to lock the first shaft.
