摘要： A stationary brake member (45) which is used in an electromagnetic brake apparatus, comprises a first press-worked plate (45h) and a second press-worked plate (45m) which are laminated to each other. The second press-worked plate (45m) has plural hooks (45q), (45s) to grip the first press-worked plate (45h). The first press-worked plate (45h) has plural projections (45k) with spaces (45t) therebetween, and the projections are buried in the cast bracket (31), whereby the first press-worked plate (45h) is firmly fixed to the bracket (31).

摘要： A sewing machine control box mounted on a non-operative end of a sewing machine frame, and including a partition board which divides the control box into first and second chambers. A transformer which gives off heat in operation is provided in a first chamber, and a printed circuit board which otherwise might be damaged by the heat generated by the transformer is provided in a second chamber. The dividing of the control box into these first and second chambers prevents excessive heat transfer from the transformer to the printed circuit board during operation of the sewing machine.

摘要： In the pedal assembly of a sewing machine drive device, a potentiometer operating member is guided by a mounting stand secured to the pedal stand, to control the slide shaft of a direct acting type potentiometer, and a speed changing pedal including a depressing board to depress the potentiometer operating member with its one end portion is coupled to the pedal stand with the other end portion. When the speed changing pedal is stepped on, a signal is outputted to change the speed of rotation of the sewing machine according the movement of the pedal thus stepped on. The pedal stand may have an opening with which the pedal is swingably engaged. In addition, signal pedals may be arranged in alignment with the speed changing pedal with the same mounting means provided at the position of those pedals, so as to allow the pedals to swap in position with one another.
