PROBLEM TO BE SOLVED: To smoothly rotate an engagement member for capturing a wheel of a two wheeler by a smaller force. SOLUTION: In order to make a torque applied to an engagement member when a part of the engagement member is contacted and rotated with an end part of a side plate of a wheel passage larger, a movable member is movably mounted to a side part of the wheel passage along this wheel passage. The movable member is provided such that a part thereof is butted to an advancing wheel. An engagement member of the wheel is turnably mounted to the movable member and when the movable member is moved to a depth by the wheel, the engagement member is moved to a depth along the side plate while it is inwardly turned by contacting a part of the engagement member with the end part of the side plate of the wheel passage. The engagement member is obstructed by the side plate and cannot be reversed and the side plate is provided on the wheel passage so as to capture the wheel. When a part of the engagement member is contacted and rotated with the end part of the side plate of the wheel passage, a distance between the end part and the turning shaft is provided such that a torque of the engagement member becomes larger. In the engagement member of the wheel catcher, a projection part is formed on a side of a side contacted with the end part of the side plate in a direction left from the turning shaft.
