The chuck includes two cylinder apparatuses, a first rod, a second rod, and a cam member. The first rod being slidably disposed within the inside of the second rod. The cam member is formed at the tip of each rod and is used to convert the reciprocal operation of each rod into the opening and closing operations of the jaw members. A notch is formed in the side of the second rod, and the cam member of the first rod protrudes out from the second rod through this notch to connect to the jaw member.
