Abstract: A handlebar mounting apparatus and method for mounting a handlebar onto a vehicle. The handlebar is mounted to the vehicle such that the handlebar is selectively rotatable about a first axis to allow for adjustment of the axial orientation of the handlebar relative to the vehicle.

One embodiment provides an apparatus for mounting a handlebar to a vehicle including two or more mounts. The use of multiple mounts or mounting assemblies in such embodiments allows the mounts to be separated or spaced from one another, and allows for universal fit of the handlebar mounting apparatus on a broad variety of vehicles and applications.

Abstract: In a tensioner for a timing belt or chain in an engine, a plunger, which is spring-biased in a protruding direction, is temporarily held in a retracted condition by a pivoted U-shaped or L-shaped wire spring. The spring has a locking portion engageable with a pin or groove on the plunger, and two arms having ends remote from the locking portion. The ends are pivoted to the housing on laterally displaced pivot axes. The lateral displacement of the pivot axes causes the wire spring to be under stress when its locking portion is engaged with the plunger, and the stress urges the locking portion toward a disengaged position. Thus, the plunger is held in its retracted condition during assembly by the locking portion of the wire spring, but is automatically released by disengagement of the locking portion from the plunger when the plunger is moved farther in the retracting direction.

Abstract: A pedal release structure for a parking brake is disclosed. The structure preferably includes a locking lever rotatably mounted on an assembly bracket, a resilient unit for resiliently supporting the locking lever in order to rotate the locking lever in an opposite direction from the return direction of the parking brake pedal, a rotation scope limiting unit for limiting the rotation scope of the locking lever, a locking unit for allowing a release lever to lock the locking lever according as the release cable is pulled, and a releasing unit for allowing the release lever locked by the locking lever to be released. With this structure the release lever is enabled to continue acting on a torsion spring until the parking brake pedal is completely released even when the return speed of the parking brake pedal is slowed due to cold temperature.

Abstract: A silent chain transmission mechanism includes a sprocket and a silent chain having link interleaved link rows each composed of plural randomly selected link plates and connected together by connecting pins. The outside dimensions of the link plate are smaller than the outside dimensions of a link, but the outside dimensions of the link match the design reference dimensions of a link plate capable of proper meshing with the sprocket. The requirement for manufacturing accuracy and the effort required for assembly of the silent chain are reduced. However, the silent chain travels on the sprocket on the chain traveling line so that improved noise, vibration and friction properties, and traveling stability are realized.
