Abstract

In an accelerator device, a pedal is rotatable in an accelerator opening direction by a pedaling force of a pad. An arm connects the pedal to the pad. A biasing member biases the pedal in an accelerator closing direction via the arm. The arm has a shaft portion that is assembled to the pad, and the pad has a pair of support walls that rotatably support the shaft portion. The pair of support walls have wall surfaces facing each other, each of the which is provided with a bearing portion and a thickening portion. The thickening portion includes a curved surface or a slope surface having a surface area broader as a distance from the bearing portion increases.

Claims4

Dependent claims

An accelerator device comprising:

a pad configured to be stepped on by a driver;
a pedal configured to be rotatable in an accelerator opening direction by a pedaling force of the pad;
an arm connecting the pedal to the pad;
and
a biasing member configured to bias the pedal in an accelerator closing direction via the arm, wherein
the arm has a shaft portion assembled to the pad,
the pad has a pair of support walls configured to rotatably support the shaft portion,
the pair of support walls have wall surfaces facing each other,
each of the wall surfaces facing each other is provided with a bearing portion in which the shaft portion is fitted, and a thickening portion which makes a root side of the support wall thicker than a tip side of the support wall, and
the thickening portion includes a curved surface or a slope surface having a surface area that is broader as a distance from the bearing portion increases.
