Brake operating apparatus

摘要

A brake operating apparatus includes a brake pedal lever pivotally attached to a bracket, an output member provided between the brake pedal lever and a brake actuating device, and a lever-ratio-changing mechanism provided between the brake pedal lever and the output member. The lever-ratio-changing mechanism includes a link member provided on one side of the brake pedal lever and rotatably attached thereto via a support shaft. The link member is linked to a rear end portion of the output member via a link shaft provided on the link member at a position offset radially from the support shaft by a predetermined amount. An interlocking mechanism is provided on the side of the brake pedal lever and between the stationary member and the link member. The interlocking mechanism causes the link member to rotate about the support shaft in accordance with pivotal movement of the brake pedal lever.
