Patent ID: 7017441

Claim:
A pedal device for a vehicle, comprising: a depressable portion which is to be operationally depressed by a driver of the vehicle; a out put member pivotably supported by a supporting shaft provided in a bracket that is fixed to a body of the vehicle, such that said output member is pivoted about said supporting shaft when said depressable portion is operationally depressed, for thereby applying to a motive-power transmitting member an output corresponding to a depression force which is applied to said depressable portion; a longitudinal adjustment device to move said depressable portion in a longitudinal direction of the body of the vehicle when said depressable portion is not being operationally depressed; and a pedal-ratio varying mechanism which is disposed between said output member and said motive-power transmitting member, and which changes a pedal ratio in relation to a depressing stroke of said pedal device; wherein said pedal-ratio varying mechanism comprises a pivot lever supported by an attaching shaft parallel to said supporting shaft and provided in said bracket such that said pivot lever is pivotable about said attaching shaft, said pivot lever being connected to said motive-power transmitting member through a first connecting shaft parallel to said attaching shaft such that said pivot lever is pivotable relative to said motive-power transmitting member about said first connecting shaft, and a connecting link connected to said pivot lever through a second connecting shaft parallel to said attaching shaft such that said connecting link is pivotable relative to said pivot lever about said second connecting shaft, said connecting link being connected to said output member through a third connecting shaft parallel to said second connecting shaft such that said connecting link is pivotable relative to said output member about said third connecting shaft, and wherein said depression force applied to said depressable portion is transmitted from said output member to said motive-power transmitting member via said connecting link and said pivot lever.
