A chuck device 40 includes a plurality of types of chuck pawls 51 clamping a component, a chuck pawl switching mechanism 58 switching the chuck pawls 51 in use among the plurality of types of chuck pawls 51 in accordance with the type of the component to be clamped, and a driving mechanism 65 allowing the chuck pawl 51 switched by the chuck pawl switching mechanism 58 to be put into a clamping operation. The chuck pawl switching mechanism 58 is configured to use a cylindrical cam 50, the plurality of types of chuck pawls 51 are placed at predetermined intervals around the cylindrical cam 50, a cam follower 57 disposed in each of the chuck pawls 51 is fitted into a cam groove 52 in an outer peripheral surface of the cylindrical cam 50, and the respective chuck pawls 51 are moved upward and downward independently of each other by the cylindrical cam 50 being rotated. In this manner, the only one pair of chuck pawls 51 in use are lowered to a lowermost position and the chuck pawls 51 not used are retracted to an uppermost position not interfering with the clamping operation of the chuck pawls 51 in use. |
