<p>PURPOSE:To provide the main body of a cylinder between a front shell and a rear shell, thereby to obtain an atmospheric pressure type having little deformation of shells and maintaining high function. CONSTITUTION:By stepping the foot pedal, the reaction of a force applied to the piston of a master cylinder 3 is transmitted from the main body of the master cylinder 3 to a spacer 5, and further through the main body 4 of the cylinder to a toe board 2. Accordingly, a tensile strength for resisting against said reaction force is not almost applied to the front shell 1a and the rear shell 1b. Accordingly, the deformation of front and rear shells 1a and 1b becomes minimum, and the problem of the loss stroke of the toggle joint can be improved greatly.</p> |
