PROBLEM TO BE SOLVED: To provide claws for suppressing deviation of an axis arm in a two-wheel barrow.MEANS FOR SOLVING THE PROBLEM: A claw groove bottom 21 to which a hub shaft 3 abuts is formed into an arc shape, in a rear claw 1, and a front end part 23 of the claw groove bottom contacts the hub shaft 3 on a lower part of a shaft center sc of the hub shaft 3. Therefore, since the front end part 23 of the claw groove bottom 21 contacts the hub shaft 3, even when downward force F is applied to the hub shaft 3, the front end part 23 serves as a catch, so that deviation of the hub shaft 3 is suppressed.SELECTED DRAWING: Figure 1

    【課題】二輪車において車輪軸のずれを抑制するつめを提供する。【課題を解決するための手段】後つめ1において、ハブ軸3が突き当てられるつめ溝底21を円弧状に形成し、その前端部23がハブ軸3の軸心scよりも下方においてハブ軸3に接するように設ける。このようにつめ溝底21の前端部23がハブ軸3に接しているので、ハブ軸3に下向きの力Fが加わっても、前端部23が引っかかりとなって、ハブ軸3のずれを抑制することができる。【選択図】図1
