1. A barrel cam device comprising:
a barrel cam;
an output table
that includes a plurality of cam followers that engage with the barrel cam, and
that rotates by rotation of the barrel cam; and
a clamp device that clamps the output table when the output table is stopping;
wherein the barrel cam device further comprises a supporting portion that rotatably supports the output table;
wherein the clamp device includes,
a plate member that includes
a fixed portion that is fixed to the output table, and
an opposing portion that faces the supporting portion with being in a non-contact state, when the output table is rotating, and
a pressing member that presses the plate member against the supporting portion when the output table is stopping, the pressing member being a piston member that deforms the opposing portion and presses the opposing portion against the supporting portion by moving and being in contact with the opposing portion when the output table is stopping;
wherein the barrel cam device further comprises a rotating shaft body,
that is mounted to a central portion of the output table and
that rotates integrally with the output table; and
wherein the piston member is provided throughout from a side where the barrel cam is located when viewed from the rotating shaft body to a side where the barrel cam is not located when viewed from the rotating shaft body.
