The first rotating shaft 208 is further transmitted to the first rotating shaft 224 . In order to stop the rotation of the shaft 224, the solenoid 21
6 and moves the rod 218 in the direction of arrow X, the latch 218 rotates about axis 220 in the direction of arrow Y. Therefore, the housing 206, which had been rotating in the direction of the arrow W, stops rotating as the cam 212 and the tip of the latch 218 engage. Then, since both ends of the coil spring 200 shown in FIG. 3 are fixed to the first rotating shaft 202 and the housing 206, a force is applied in the direction of loosening and expanding the diameter, thereby releasing the second rotating shaft 208. Therefore, the connection between the second rotating shaft 208 and the first rotating shaft 202 is released.

Figure 1 (a) Figure 2 Figure 3 Procedural amendment February 27, 1988 Commissioner of the Japan Patent Office Kuro 1) Yu Akira 1, Indication of the case 1986 Patent application No. 244938 26 Name of the invention Reverse operation Electromagnetic spring clutch 3, relationship with the case of the person making the amendment Patent applicant 4, attorney 6, number of inventions increased by the amendment 7, subject of the amendment 8, content of the amendment 1) The scope of the claim has been changed as follows: to correct. [1. In normal conditions, a first rotating shaft and a second rotating shaft, which are arranged coaxially or with their axes aligned, are tightly connected by a coil spring, rotated together, and are rotated by a predetermined operation. In a mechanism that loosens the tightening of the coil spring and releases the connection between the first rotation shaft and the second rotation shaft, an electromagnetic coil R1 of 11 knots and 71 circles, the field core and the electromagnetic coil are connected. a first rotary shaft that is rotatably supported; and a first rotary shaft that is rotatably disposed on the first rotary shaft, coaxially with the first rotary shaft or with its axis aligned with the first rotary shaft. an armature coaxially fitted onto the first and second rotation shafts; and an armature disposed between the armature and the first and second rotation shafts; The end portion of the field conial armature is provided with a coil spring hooked to the armature, and a yoke having a through hole into which the field conial armature is loosely inserted, or a flange formed at a predetermined position of the armature, and the coil spring is connected to the electromagnetic field. When the coil is not energized, the first rotating shaft and the second rotating shaft are connected by reducing the diameter and tightening the coil, and when the electromagnetic coil is energized, the diameter is expanded and the tightening is loosened, and the first rotating shaft and the second rotating shaft are connected by reducing the diameter and tightening the coil. A reverse action electromagnetic spring clutch is characterized in that a first rotating shaft and a second rotating shaft are disconnected from each other. 2) In the 1st to 3rd lines of page 7 of the specification, amend "Put in a U-shaped cross section...inside a U-shaped" to "Place in the field core." . 3) "The armature is located in the field core" on page 7, lines 12 and 13 of the specification is corrected to "the armature is located in the field core." 4) Insert the following sentence between the third and fourth lines of page 13 of the specification. "Furthermore, the field core 10 may have any shape as long as it has sufficient magnetic force."

動電磁スプリングクラッチ。[Claims] 1. In a normal state, a first rotating shaft and a second rotating shaft, which are arranged coaxially or with their axes aligned, are tightly connected by a coil spring and rotated together. , a field core formed in a U-shaped cross section with one end open in a mechanism for loosening the tightening of the coil spring by a predetermined operation and releasing the connection between the first rotation shaft and the second rotation shaft; , an electromagnetic coil arranged in a U-shape of the field core, a first rotating shaft rotatably supported through the field core and the electromagnetic coil, and a first rotating shaft supported on the first rotating shaft. a second rotating shaft coaxial with the first rotating shaft or rotatably disposed with its axis aligned with the first rotating shaft; and a second rotating shaft coaxially fitted on the first rotating shaft and the second rotating shaft. an armature, a coil spring disposed between the armature and the first rotating shaft and the second rotating shaft, one end of which is hooked to the armature, and a U-shaped end of the field core. The coil spring has a yoke that is fixed and has a through hole into which the armature is loosely inserted, or a flange formed at a predetermined position of the armature, and the coil spring is connected to the first rotating shaft and the first rotating shaft when the electromagnetic coil is not energized. The first rotating shaft and the second rotating shaft are connected by reducing the diameter and tightening the coil, and when the electromagnetic coil is energized, the diameter expands and the tightening is loosened, and the connection between the first rotating shaft and the second rotating shaft is released. A reverse action electromagnetic spring clutch that is characterized by:
