Abstract
A clutch device used to couple/decouple a reciprocating force of a drive member to/from a needle bar in a sewing machine includes an actuating lever actuated by an electromechanical unit to be pivotable between an idle position to disengage from an actuated end of a clutch lever so as to leave a grasp end of the clutch lever in a coupled state, where the grasp end is engaged with a coupled portion disposed on a drive member, thereby transmit the reciprocating force to the needle bar, and an actuating position to be in pressing engagement with the actuated end so as to displace the grasp end to a decoupled state, where the grasp end is disengaged from the coupled portion.
