1. An air chuck comprising:
a finger support part including a pair of fingers that is openable and closable;
a chuck main body part including an operation mechanism operable to open and close the pair of fingers; and
linking mechanisms that detachably link the finger support part to the chuck main body part, wherein
the finger support part includes two linking shafts extending from the finger support part, the two linking shafts being parallel to each other,
the two linking shafts are provided with the two respective linking mechanisms, and the linking mechanisms each include: a catch surface formed on the linking shaft; a shaft insertion hole formed in a body of the chuck main body part for insertion of the linking shaft; a catch body that becomes elastically caught on the catch surface of the linking shaft so as to link the linking shaft to the chuck main body part when the linking shaft is inserted into the shaft insertion hole; and a delinking member that is manually operated so as to release the catch body caught on the catch surface when the finger support part is detached from the chuck main body part,
the linking mechanisms each include the catch body received in a manner so as to be capable of shifting between a catch position where the catch body is caught on the catch surface of the linking shaft and a non-catch position where the catch body is off the catch surface; and a press member capable of shifting between a press position where the press member presses the catch body toward the catch position and a non-press position where the press member does not press the catch body,
a mounting hole is formed on the body of the chuck main body part, and the delinking member is fitted in the mounting hole, and
the delinking member causes the press member to shift to the non-press position by operating the delinking member within the mounting hole when the finger support part is detached from the chuck main body part.
