Abstract:
A brake pedal apparatus for a brake device comprising:an input shaft for the brake device; first and second pivot pins; a first lever member having a middle portion pivotally supported to a vehicle body by the first pivot pin; a second lever member having one end with a pedal member and the other end pivotally connected to one end of said first lever member by the second pivot pin, said second lever member being operationally connected to the input shaft for the brake device; pivotal movement control means connected to the first lever member for controlling a pivotal movement of said first lever member in such a manner as to prevent the pivotal movement of said first lever member when a predetermined condition is not satisfied and to allow the pivotal movement of said first lever member when the predetermined condition is satisfied, said pivotal movement control means including a receiving portion disposed at a position facing the one end of said first lever member; engaging means disposed on the other end of said first lever member and capable of engaging said receiving portion; and engagement control means for controlling an engagement between said engaging means and said receiving portion in such a manner as to disengage said engaging means by the satisfaction of said predetermined condition, which engages said receiving portion to prevent the pivotal movement of said first lever member, from said receiving portion to allow the pivotal movement of said first lever member; and coupling means for coupling said first and second lever members, said coupling means, when the pivotal movement of said first lever member is allowed, rotating the second lever member together with the first lever member around the first pivot pin by pushing the pedal member to actuate the input shaft to thereby change a pedal ratio of the pedal member.
