1. A machine tool hand comprising:
a body portion comprising a flow path, the body portion configured to be detachably mounted to a spindle of a machine tool and the flow path configured to fluidically connect with a coolant-liquid supply path formed in the spindle;
a plurality of hand members which are attached to the body portion such that at least one of the plurality of hand members is pivotable about a prescribed axis; and
a movable body configured to push a first of the plurality of hand members,
wherein the plurality of hand members are capable of gripping an object therebetween when closed,
wherein the flow path is provided with discharge ports via which a coolant liquid supplied from the coolant-liquid supply path is discharged from the body portion to impinge upon surfaces of the plurality of hand members, the surfaces being disposed to an outside of the body portion,
wherein the movable body is arranged within a first of the discharge ports such that the coolant liquid pushes the movable body against the first of the plurality of hand members, causing the first of the plurality of hand members to open, and such that a remainder of the coolant liquid passes around the movable body as the coolant exits the body portion through the first of the discharge ports.
