Abstract

PURPOSE: To permit a parking brake to be more accurately and safely operated by converting the operating force on a parking brake into a pressure, and generating a signal when said pressure conversion value reaches a value above a setting value.
CONSTITUTION: When a handle of a parking brake is operated to actuate the brake, a rod 8 moves in the direction of an arrow A. When the brake-operating force is above a setting value, an inner cylinder 12 fixed to the rod 8 deviates relatively to a case 11 in the A direction against the energizing force of a spring 17. When the deviation reaches C2, a snap ring 21 to be one contact and a contact 22 are connected to establish an electric continuity, which causes a lamp 23 to light up in order to let an operator know that the braking force needed for the parking brake has been applied.
