合されている。2. Description of the Related Art Conventionally, in a lever of a pivot solenoid of this type, as shown in FIG. 1, a bearing body 1 is made of resin such as nylon by insert molding in a lever body 5 made of a magnetic material. . The lever thus constructed is used in a pivot solenoid having a structure as shown in FIG. 2, and is rotatably engaged by a pin 4 fixed to the bobbin 2 or the frame 3.

スｌがなくなり動作不能となる等の欠点があった。(2) The bearing 1 made of a resin such as nylon generally contains glass fiber in order to improve durability. However, as the operation continues, the pin 4 is worn by the glass fiber exposed on the surface of the resin, the backlash is generated in the bearing portion 1, and finally the clearance 1 between the lever and the frame 3 disappears. There was a defect that it became impossible.

図ることが可能となる。In FIG. 4, the lever bearing portion 1'which is rotatably engaged with the pin 4 is formed of a polyimide resin, has excellent wear resistance, and does not contain glass fibers or the like. Since the pins 4 are not damaged, it is possible to prolong the service life.

圧入で懸念される。軸受部１′の廻りも防止される。The bearing portion 1'is pressed into the lever body 5 to form a lever assembly. Therefore, it is not necessary to perform insert molding as in the past, and workability is excellent. Also, by having the rotation stop protrusion 7,
I am concerned about the press fit. The rotation of the bearing 1'is also prevented.

をしにくい工業用ミシン等への応用が考えられる。According to the present invention, the life of the pivot solenoid has been about 1 × 10 8 times in the past (3), but it has been extended to 7 × 10 8 times by about 7 times. Therefore, it can be considered to be applied to an industrial sewing machine or the like, which is hard to perform maintenance in equipment such as continuous operation at day and night and maintenance free.
