付性が悪いという問題をもつ。 In a conventional electromagnetic clutch, as shown in FIG. 1, a clutch rotor 2 is rotatably disposed on a fixed part of a driven device 1, and a main shaft 3 that protrudes outward from the driven device 1 has a clutch rotor 2 rotatably disposed on a fixed portion of a driven device 1. A boss (hub) 4 is fixed to the end, and a suction plate 6 supported by a plurality of leaf springs 5 is opposed to the shaft end surface of the clutch rotor 2 with a gap therebetween, and is connected to the excitation coil 7. By energizing the clutch rotor 2, the suction plate 6 is attracted to the clutch rotor 2, thereby transmitting rotational motion. In that case, a washer-like spacer 8 is further interposed between the boss 4 and the leaf spring 5, a stop plate 9 is superimposed on the leaf spring 5, and these are tightened and fixed with rivets 11, and the stop plate By bringing a stopper 12 provided on the outer periphery of the plate 9 into contact with the suction plate 6, an initial deflection is given to the leaf spring 5. Note that the stopper 12 may be made of rubber or the like separately from the stop plate 9. However, in the case of the structure shown in FIG. 1, the spacer 8, leaf spring 5, and stop plate 9 are stacked on the boss 4, and all of these are tightened with the rivets 11, so there are a large number of parts, and The problem is that it is difficult to assemble.

付性が悪い等の問題をもつ。 Furthermore, as shown in FIG. 2, a structure in which a stopper 12 is provided on the leaf spring 5 is also known. This structure has the advantage of eliminating the need for a stop plate.
However, there are problems such as high dimensional accuracy is required for each leaf spring 5 in order to determine the height of the stopper 12, and ease of assembly is poor.
それ故に本考案の目的は、上述に鑑み、安価で
しかも組付性の良い電磁クラツチの提供にある。 Therefore, in view of the above, an object of the present invention is to provide an electromagnetic clutch that is inexpensive and easy to assemble.

様である。 FIGS. 3 and 4 show an embodiment of the electromagnetic clutch according to the present invention, taking as an example the case where it is installed in a compressor for a car cooler. clutch rotor 2
is a V-belt (not shown) rotatably arranged via a ball bearing 14 on the outer periphery of a cylindrical protrusion 13 provided on a fixed part of the driven device, that is, the compressor 1, and hung in a V-groove 15 on the outer periphery. Rotationally driven by a drive source via. Further, a suction plate 6 is disposed on the outer periphery of the boss 4 fixed to the outer end of the main shaft 3 which passes through the inside of the cylindrical projection 13 and is exposed to the outside. It is supported on the shaft end surface of the boss 4 by. In this way, the suction plate 6 is opposed to the clutch rotor 2 in the axial direction. Further, the ring-shaped excitation coil 7 inserted into the ring-shaped groove 16 of the clutch rotor 2 is fixedly supported by a fixed part of the compressor 1. The excitation coil 7 includes the clutch rotor 2 and the attraction plate 6 in a magnetic circuit, and when the excitation coil 7 is energized, the attraction plate 6 attracts the clutch rotor 2 and transmits rotational motion to the main shaft 3, which is different from the conventional method. It is similar to

を重ねてリベツト１１にてボス４に固着される。 Each leaf spring 5 has one end riveted to the boss 4.
1, and the other end is fixed to the suction plate 6 with another rivet 17. At this time, a plate-shaped spacer 18 is interposed between the shaft end surface of the boss 4 and the leaf spring 5, and this spacer 18 is also fixed to the boss 4 with a rivet 11 together with the leaf spring 5. Spacer 1
8 is a boss 4 on the main shaft 3, as is clear from Fig. 4.
A plurality of extension parts 18b extending radially outward are provided on a ring-shaped part 18a positioned on the outer periphery of a nut 19 fixing the nut 19.
The number of extension portions 18b is the same as the number of leaf springs 5,
A leaf spring 5 is attached to the base of the extended portion 18b.

い。 The extended portion 18b extends until it faces the suction plate 6, and has a stopper 18c at the portion facing the suction plate 6. This stopper 18c is formed by partially pushing out the extension portion 18b toward the suction plate 6. In this way, the stopper 18c is brought into contact with the suction plate 6, and the leaf spring 5 is given an initial deflection. Note that the stopper 18c may be constructed by attaching a member made of rubber or the like that is separate from the spacer 18 to the extension portion 18b of the spacer 18.

しかも組付性のよい電磁クラツチが得られる。 According to the above-described structure, not only a stop plate is not required, but also a separate washer-like spacer does not need to be interposed between the boss 4 and the leaf spring 5, so that the assembly work is simple. Furthermore, since a spacer 18 is interposed between the leaf spring 5 and the boss 4 to separate the leaf spring 5 from the boss 4, there is no need to worry about the leaf spring 5 interfering with the boss 4 during operation. 5 can be given a sufficiently large initial deflection. Further, since the plurality of stoppers 18c for giving initial deflection to the leaf spring 5 are provided on the extension portion 18b of the integrally structured spacer 18,
It is easy to improve dimensional accuracy. Therefore, an electromagnetic clutch that is inexpensive and easy to assemble can be obtained.
