Abstract
A sewing machine has a bed housing having a needle penetrating hole at one end thereof, an arm housing rising from the other end of the bed housing and extending to the one end of the bed housing over the bed housing, a laterally-long needle bar arm rotatably held in the arm housing and having a needle at the front end thereof, and a drive unit for swinging the needle bar arm with respect to the bed housing accommodated in the bed housing. The arrangement of the laterally-long needle bar arm and the drive unit accommodated in the bed housing, can effectively reduce the overall height of the sewing machine. It further reduces the weight and cost of the sewing machine, since no conventional material, such as cast iron having a heavy weight is used and die cast aluminum associating with a higher cost, may be employed for producing the arm housing.
