Abstract

A brake pedal device includes: a pedal bracket fixed to a dash panel; an operation pedal mechanism having a step portion rotatable with respect to the pedal bracket and in which the step portion is stepped forward of a vehicle; a rotating member having a bent portion, a front end portion, and an upper end portion, and rotatably supported with respect to the operation pedal mechanism by a rotating shaft portion at the bent portion; a connecting pin and a clevis that rotatably hold a tip portion of an operating rod projecting rearward of the vehicle from the dash panel with respect to the rotating member, at the front end portion of the rotating member; and a caulking pin that fixes the rotating member and the operation pedal mechanism, at the bent portion of the rotating member.

First claim

What is claimed is:

1. A vehicular operation pedal device comprising:
a support member fixed to a first vehicle component;
an operation pedal mechanism provided in the support member and having a step portion rotatable with respect to the support member, and in which the step portion is stepped forward of a vehicle;
a rotating member having a bent portion, a front end portion extending forward of the vehicle from the bent portion, and an upper end portion extending upward from the bent portion, and rotatably supported with respect to the operation pedal mechanism by a rotating shaft portion at the bent portion;
a connecting portion that rotatably holds an input portion of a vehicular control mechanism projecting rearward of the vehicle from the first vehicle component with respect to the rotating member, at the front end portion of the rotating member; and
a fixing member that fixes the rotating member and the operation pedal mechanism at the bent portion of the rotating member, and to which a first load is applied when the step portion of the operation pedal mechanism is fully stepped forward of the vehicle, wherein
the operation pedal mechanism comprises:
an operation pedal that is rotatably supported with respect to the support member by an operating shaft portion provided at an upper end portion of the operation pedal and is provided with the step portion at a lower end portion of the operation pedal; and
an intermediate lever that is rotatably supported with respect to the support member by an intermediate shaft portion provided at a lower end portion of the intermediate lever, and is provided with the rotating shaft portion and the fixing member at an upper end portion of the intermediate lever, in which an intermediate portion of the intermediate lever is connected to the operation pedal by a link member, between the upper end portion and the lower end portion of the operation pedal,

an amount of operation by stepping on the step portion is transmitted to the vehicular control mechanism via the rotating member and the connecting portion,
when the first vehicle component is displaced rearward of the vehicle at the time of a vehicle collision, the upper end portion of the rotating member comes into contact with a second vehicle component disposed rearward of the vehicle from the first vehicle component, so that a second load is applied to the fixing member, and
when the second load is greater than the first load, fixation of the rotating member and the operation pedal mechanism by the fixing member is released, the upper end portion of the rotating member is rotated forward of the vehicle about the rotating shaft portion, and the front end portion of the rotating member and the input portion of the vehicular control mechanism are displaced downward via the connecting portion, so that the step portion of the operation pedal mechanism is displaced forward of the vehicle with respect to the first vehicle component.

2. The vehicular operation pedal device according to claim 1 , wherein
the input portion of the vehicular control mechanism is a tip portion of an operating rod, and controls the vehicle by being displaced in an axial direction of the operating rod by an operating load on the step portion, and
the rotating shaft portion is disposed on an axis of the operating rod.

3. The vehicular operation pedal device according to claim 1 , wherein the fixing member is a caulking pin that restricts rotation of the rotating member with respect to the operation pedal mechanism by caulking while being inserted through a mounting hole provided in the operation pedal mechanism and a mounting hole provided in the rotating member.

4. The vehicular operation pedal device according to claim 1 , wherein the fixing member comprises:
a bolt inserted into an elongated hole formed along an arc about the rotating shaft portion at the bent portion of the rotating member; and
a nut screwed into the bolt.
