To provide a configuration that is capable of securing a necessary contact area between a cum surface of a cam and an inside end surface of a lock gear even when the cam is displaced relatively in an axial direction with respect to the lock gear.SOLUTION: On a surface facing lock gears 61, 62 and a cam 70 of a base plate 30, a circular recess 36 into which one side in an axial direction of the cam 70 enters is formed. The cam 70 is formed so that length T1 in the axial direction of the cam surface 72 is longer than length T2 in the axial direction of inside end surfaces 61c, 62c in the lock gears 61, 62.SELECTED DRAWING: Figure 6

    【課題】カムがロックギヤに対して相対的に軸方向にずれる場合でも、カムのカム面とロックギヤの内側端面との間で必要な接触面積を確保し得る構成を提供する。【解決手段】ベースプレート30のうちロックギヤ61,62及びカム70に対向する面には、カム70の軸方向一側が入り込む円形状の凹部36が形成され、カム70は、カム面72の軸方向長さT1がロックギヤ61,62における内側端面61c,62cの軸方向長さT2よりも長くなるように形成される。【選択図】図6
