<p>An automatic brake pedal operation apparatus is provided to prevent a piston rod from advancing abruptly in case a worker applies heavy load to a pressing pedal by installing a damping spring in a cylinder, thereby preventing damage of a brake pedal. An automatic brake pedal operation apparatus comprises a cylinder, a support unit(20), a power supply unit(30), and a piston rod(40). Pistons reciprocate in the cylinder. The support unit is installed to a base end portion of the cylinder to support the cylinder. The power supply unit is installed to supply air or fluid to a hose(33) connected to the cylinder. The piston rod is connected to the piston and reciprocates in and out of the cylinder. A holding unit(41) is installed to a front end portion of the piston rod to hold a brake pedal. The power supply unit includes an air tank(31), and a pressing pedal(32). The pressing pedal is connected to the air tank to feed air into the cylinder via the hose. Damping springs are installed inside the cylinder to decelerate advancing speed of the pistons.</p> |
