A resistance generating device for a vehicle includes first and second transmission members placed next to each other along a rotary axis of the transmission members and a fixing member provided to form a clearance between the fixing member and a set of the plural transmission members in a radial direction of the rotary axis of the set of the plural transmission members. Each of the transmission members includes a position changing portion generating or releasing a resistance against a rotary motion of a rotary body so that the first transmission member is aligned in line with, or is displaced from the second transmission member along the rotary axis in a case where the first transmission member and the second transmission member rotate in accordance with a rotation of the rotary body, or in accordance with a rotation of a power receiving portion in response to a power.
