Accelerator device

An accelerator device, comprising:

• a pedal lever configured to operate in response to a pedal operation;
• a drive source configured to generate a driving force by an energization;
• a power transmission mechanism including a first power transmission member having a first stopper and to which the driving force of the drive source is transmitted, a second power transmission member having a second stopper configured to come into contact with the first stopper, a coupling elastic member having one end locked to the first power transmission member and the other end locked to the second power transmission member, and an actuator lever configured to come into contact with the pedal lever, and being configured to apply a reaction force, which is a force in a direction opposite to a depression direction, to the pedal lever via the first power transmission member, the second power transmission member, and the actuator lever by the driving force of the drive source;
• and
• a lock mechanism including a locking member and a locked portion, and being configured to regulate an operation of the pedal lever by moving the locked portion to a locking position by the driving force of the drive source and being locked by the locking member;
• wherein
• the first stopper and the second stopper are separated from each other in an initial state when the pedal lever is fully closed and the energization to the drive source is turned off, and come into contact with each other when the first power transmission member is driven against an elastic force of the coupling elastic member by energizing the drive source.
