PURPOSE:To make respective brake mechanisms operable without interfering to each other by providing a buffer mechanism by which, even if one link mechanism is operated, the other link mechanism is not operated simultaneously, in the foot brake mechanism and parking brake mechanism in a folk lift, etc. CONSTITUTION:First and second brake link mechanisms 1, 2 are disposed in a brake pedal 61 and a parking lever 62, respectively, and the first link mechanism 1 is constituted in such a manner as to connect a pedal rod 11 to a brake lever 52 through a link 12, an intermediate rod 13, a spring 14, a connecting pipe 30, and a rod 18. The second link mechanism 2 is constituted in such a manner as to connect a parking rod 21 to the same brake lever 52 through a link 22, and intermediate rod 23, a spring 24, a connection arm 32, and a rod 28. The links 12, 22 have respective long holes 12A, 22A on their end parts, and engaging arms 130, 230 on respective one ends of the intermediate rods 13, 23 are engaged with these holes in such a manner as to be capable of sliding, and made to function as a buffer mechanism A. |
