In addition, the suction port 24, the oil supply ports 34, 38,
Small pieces 42, 44, 46 are inserted respectively. A cam 48 that rotates as the lower shaft 28 rotates is inserted into the center of the oil pump 20.
is a circular shape with a part cut out. Further, a pressing piece 50 is in contact with the cam 48, and the mounting plate 5
The pressing piece 50 is pressed against the cam 48 by the pressing spring 54 attached by 2. Note that a filter 22 is attached to the bed 16 by a filter attachment plate 56, and one end of the suction pipe 26 is immersed in the filter 22.

8, the central angle of the outer periphery excluding the gap 58 is large (approximately
220 degrees), and the two oil fill ports 34 and 38 are arranged in parallel facing the direction of movement of the cam 48, so when the sewing machine is stopped, etc., one side of the oil fill ports 34 and 38 Even if air enters the fuel filler port, there is little risk that the air will escape because the other side of the fuel filler port is blocked by the outer peripheral portion of the cam 48.
Therefore, oil does not flow backward in the oil supply pipes, and the oil supply pipes 30 and 40 do not flow back when the sewing machine is restarted.
It is possible to smoothly supply oil to a separate oil supply section via the
