    • PURPOSE: To provide a chuck having such a structure that an adjustment operation to prevent a master jaw from moving in the axial rear direction of the chuck can be preformed easily without disassembly of the chuck in a swing lock chuck having a clearance between the spherical part of the master jaw and the spherical guide surface of a chuck main body. CONSTITUTION: The master jaw 17 is formed so that the spherical part 18 thereof is fitted to the spherical guide surface 16 of the chuck main body 2 and a round bar part 19 is inserted slidably into a spherical bearing 12 of a drive member 5 in the chuck main body 2. A slidably contact member 30 is inserted from a chuck front face 3a into a through-hole 26 provided in the master jaw 17. Because a sliding contact arc surface 33 is brought into contact slidably with the stopper portion 36 of the chuck main body 2, the adjusting operation for the state of sliding contact can be performed easily.
    • 目的:提供一种卡盘,其具有能够容易地预先形成防止主卡爪在卡盘的轴向后方向移动的调整动作的结构,而不会在卡盘位于具有球形部分 的主颚和卡盘主体的球形引导表面。 构成:主颚17形成为使得其球形部分18装配到卡盘主体2的球形引导表面16,并且圆棒部分19可滑动地插入到驱动构件5的球面轴承12中 卡盘主体2.滑动接触构件30从卡盘前面3a插入到设置在主夹爪17中的通孔26中。由于滑动接触弧面33与滑动接触弧面33的止动部36滑动接触 卡盘主体2,可以容易地进行滑动接触状态的调整操作。
