Patent attributes
In a lever device for a hydraulic operation where hydraulic pressure is generated in a master cylinder by rotation of a lever, to make invariable an operation of a pushrod, which operates a piston of the master cylinder by being pushed at one end thereof by an adjuster of the lever, irrespectively of an adjustment of the adjuster. The lever is supported by a rotational shaft to be rotatable around the rotational shaft relative to the master cylinder, while a knocker member separate from the lever is supported to be coaxially rotatable. A knocker portion of the knocker member receives an end of the pushrod, which operates the piston. A positional relationship between the pushrod and the knocker portion is made invariable irrespectively of a change in a distance between the adjuster and the knocker portion by an adjustment of the adjuster.
