1. A pedal device to be mounted on a vehicle, the pedal device comprising:
a housing mounted on a vehicle body;
a pedal pad rotational relative to the housing and having a surface, which is to be stepped on by a driver; and
a reaction force generation mechanism including a plurality of resilient members including a predetermined leaf spring, wherein
the reaction force generation mechanism is
arranged in a space on an opposite side of the surface of the pedal pad, and
configured to generate a reaction force against a pedaling force applied to the pedal pad by the driver,
the predetermined leaf spring is
resiliently deformable when receiving a load in a plate thickness direction,
in a flat shape or in a flat shape in which at least one of a thickness or a width changes, and
in a linear shape or in a curved shape in a longitudinal direction when the load is not applied,
one end of the predetermined leaf spring is fixed to the housing or the vehicle body,
an other end of the predetermined leaf spring is a free end,
among the resilient members of the reaction force generation mechanism, at least one of the resilient members, excluding the predetermined leaf spring, is
arranged in series at the other end of the predetermined leaf spring in the longitudinal direction,
arranged between the other end of the predetermined leaf spring in the longitudinal direction and one of an abutment pin provided to the pedal pad, a connecting rod connected to the pedal pad, or the pedal pad,
the predetermined leaf spring is configured not to be restricted in an amount of bend from an initial position, at which the pedaling force is not applied to the pedal pad by the driver, to a maximum rotational position, at which the pedaling force is applied to the pedal pad by the driver and the pedal pad has rotated at maximum, and
among the resilient members of the reaction force generation mechanism, at least one of the resilient members, excluding the predetermined leaf spring, is configured to be restricted in an amount of deformation at a position between the initial position and the maximum rotational position.
