Abstract
When a dash panel P is displaced toward the rear of a vehicle upon vehicle collision, a small collision lever 60 is displaced to a release position at which a load corresponding to contact of a collision bracket 200 with a second contact portion 60A is applied to a swaging pin 15. When fixation between a rotation lever 50 and a second arm 40 via the small collision lever 60 by the swaging pin 15 is released, a step portion 21 is displaced to the vehicle front side.
Claims7
A vehicular operation pedal device, comprising:
- a support member fixed to a first vehicle component;
- an operation pedal mechanism provided on the support member and having a step portion that is rotatable relative to the support member and an operation lever that rotates toward a vehicle front side when the step portion is stepped on toward the vehicle front side;
- a rotation lever having a first contact portion extending to a vehicle rear side, supported on a vehicle lower side with respect to the first contact portion by a first rotation shaft portion so as to be rotatable toward the vehicle front side relative to the operation lever, and holding an operating rod protruding to the vehicle rear side from the first vehicle component;
- a differential lever having a second contact portion extending to the vehicle rear side and supported on the vehicle lower side with respect to the second contact portion so as to be rotatable toward the vehicle front side relative to the rotation lever by a second rotation shaft portion;
- a fixing member that fixes the differential lever and the operation lever, wherein the differential lever is, when fixed to the operation lever by the fixing member, at a restriction position at which the second contact portion protrudes to the vehicle rear side beyond the first contact portion of the rotation lever, and
- a coupling member fixed to a tip end of the operating rod;
- and
- a holding member holding the coupling member on the rotation lever,
- wherein the operation lever has a clearance hole,
- the holding member holds the coupling member on the rotation lever in a state of being housed in the clearance hole of the operation lever,
- the first rotation shaft portion is positioned on a vehicle upper side with respect to a line segment in a direction in which the operating rod extends when the differential lever is at the restriction position and the step portion is at an initial position at which stepping operation is not performed on the step portion,
- when the first vehicle component is displaced toward the vehicle rear side upon vehicle collision, a second vehicle component positioned on the vehicle rear side with respect to the first vehicle component contacts the second contact portion, so that the second contact portion is positioned on the vehicle front side with respect to the first contact portion, and the differential lever is displaced to a release position at which a load corresponding to contact of the second vehicle component with the second contact portion is applied to the fixing member, and
- fixation between the differential lever and the operation lever by the fixing member is released, so that the second vehicle component contacts the first contact portion and the rotation lever rotates toward the vehicle front side at the first rotation shaft portion.
