Abstract (en)
[origin: JPH0244617A] PURPOSE: To compensate a location tolerance in the halting state between a piston device and the rear wall of a booster housing and contact a brake alarm just after the working of a brake by connecting a plunger with a driven element by unidirectional elastic engagement means. CONSTITUTION: A driven element 13 follows the moving of a piston device 2 under the action of a spring 19 and carries an opening 26 working with a groove 30 formed on the head part of a plunger 15 each other until the contact formation area of a moving contact blade 21 or a stud 28 comes into contact with a fixed contact blade 20 against elastic stress of the blade 21 itself. The elastic engagement between the plunger and the driven element prevents the relative moving between those two parts. The driven element 13 is pressed toward the external side of a first main body part 6 by the spring 19 and the plunger is pressed in the opposite direction as a result of the elastic force of the blade 21 itself. The rigidity of this blade 21 is substantial half of that of the spring 19.
