1. A pedal device comprising:
a pedal that is configured to rotate about a rotational axis when the pedal is pressed by an operator;
a first resilient member that is configured to generate a reaction force against a pedal force applied from the operator to the pedal through deformation of the first resilient member in response to application of a force from the pedal to the first resilient member at a time of rotating the pedal;
a second resilient member that is configured to generate a reaction force against the pedal force applied from the operator to the pedal through deformation of the second resilient member in response to the application of the force from the pedal to the second resilient member at the time of rotating the pedal;
a first holder that includes a first support portion, which is placed adjacent to the pedal and supports one end part of the first resilient member, and a first guide portion, which extends from the first support portion in a deforming direction of the first resilient member, wherein the deforming direction of the first resilient member is defined as a direction in which the first resilient member is configured to deform;
a second holder that includes a second support portion, which supports another end part of the first resilient member opposite to the one end part of the first resilient member, a second guide portion which extends from the second support portion in the deforming direction of the first resilient member, and a third support portion that supports one end part of the second resilient member;
a fourth support portion that supports another end part of the second resilient member opposite to the one end part of the second resilient member; and
a third guide portion that extends from the fourth support portion in a deforming direction of the second resilient member, wherein the deforming direction of the second resilient member is defined as a direction in which the second resilient member is configured to deform, wherein:
the force applied from the pedal at the time of rotating the pedal moves the first guide portion in the deforming direction of the first resilient member to execute a relative movement of the first guide portion relative to the second guide portion, thereby causing the first guide portion to slide relative to the second guide portion in the deforming direction of the first resilient member, and resulting in the deformation of the first resilient member;
the force applied from the pedal at the time of rotating the pedal moves the second holder in the deforming direction of the second resilient member to execute a relative movement of the second holder relative to the third guide portion, thereby causing the second holder to slide relative to the third guide portion in the deforming direction of the second resilient member, and resulting in the deformation of the second resilient member; and
the third guide portion and the fourth support portion are fixed and are therefore nonrotatable.
