Abstract
An acceleration device includes: a support portion that has a communication passage, which communicates between a receiving space and an outside; a shaft that is rotatably supported by the support portion; a pedal boss portion that is located on a radially outer side of the shaft and is rotatable integrally with the shaft in the communication passage; a rotational angle sensor that is operable to sense a rotational angle of the shaft relative to the support portion; a pedal spring that urges rotation of the shaft in an accelerator closing direction; and a projection that is formed in a communication passage inner wall, which is an inner wall of the communication passage and is opposed to a boss portion outer wall of the pedal boss portion. The projection projects from the communication passage inner wall in a radially inward direction.
