Abstract
A wheel simultaneous brake mechanism for simultaneously braking two wheels includes two respective engaging members that are selectively movable between an engaged position and a disengaged position for selectively braking or releasing the two wheels. Each engaging member is biased by a spring toward its respective engaged position. The two engaging members are connected to one another in a manner transmitting a tensile force therebetween by a wire, so that the engagement or release of both engaging members can be actuated together in unison.
