なる。In FIG. 3, reference numeral 5 denotes a feed adjusting dial, which is mainly made of plastic. Reference numeral 4 denotes a feed adjusting screw fixed to a feed adjusting dial 5, which is rotatably attached to the sewing machine frame 6. Reference numeral 2 denotes a feed adjusting table, which forms two opposing contact portions 2A and 2B which are rotatably supported at the center by a rotation shaft 3. Feed adjustment table 2
Normally, a turning force in the counterclockwise direction is received by a spring (not shown), and the contact portion 2B is pressed against the distal end portion 4A of the feed adjusting screw 4. When the feed adjustment dial 5 is turned, the feed adjustment screw 4
Moves left and right in FIG. 3 to change the stitch length. In the drawing, the stitch length increases as the feed adjusting screw 4 moves to the left.

え、送り調節ダイヤル５から振動音が発生する。When the touchback switch is turned on, the feed adjusting table 2 rotates counterclockwise by an electromagnet or the like, and the contact portion 2A of the feed adjusting table 2 collides with the tip 4A of the feed adjusting screw 4. When the touchback switch is turned off, the feed adjustment base 2 rotates clockwise by the action of the spring, and the contact portion 2B of the feed adjustment base 2 comes into contact with the tip 4A of the feed adjustment screw 4. As described above, when the contact portions 2A and 2B of the feed adjustment table 2 collide with the tip 4A of the feed adjustment screw 4, the impact is given to the feed adjustment screw 4 and the feed adjustment dial 5, and vibration noise is generated from the feed adjustment dial 5. Occur.

者に不快感を与えていた。However, when the contact portion of the feed adjusting table collides with the tip of the feed adjusting screw in order to change the feed direction of the cloth, the feed adjusting dial is made of plastic and has a small mass, so that it is considerably large. Vibration noise was emitted, giving the worker discomfort.

【問題を解決するための手段】プラスチック等でできた
ミシンの送り調節ダイヤルの材料の一部に比重の大きな
材料を用いて質量を大きくする。The mass is increased by using a material having a large specific gravity as a part of the material of the feed adjusting dial of the sewing machine made of plastic or the like.
