Since Π0 is the same, the illustration and description of the f are omitted. In another aspect, as shown in FIG. 4, the special micro-disc 41 of the electromagnetic brake of the present embodiment is bonded to the two sides of the core plate by friction material 42: and the friction material 42 of the disk 41 is An elastic adhesive 44 is used on the core plate 43. As the adhesive 44, for example, a so-called elastic adhesive such as an epoxy-modified (tetra) oxy-resin or an acrylic-based denatured oxime resin can be used. 97108999 12 200914749 : In the case of ’, the thickness of the adhesive layer 44 formed of the adhesive 44 is preferably 5 μm or more. #又孜 As described above ^ constitutes 1 #帅25release electricity (adhesively absorbed due to armature, disc 41, flat plate collided with each other: impact, which can greatly reduce the release of the armature when the magnetic car The fifth embodiment of the electromagnetic brake of the present invention will be described with reference to Fig. 5', and the fifth embodiment of the electromagnetic brake according to the present invention is shown in Fig. 5, which is a longitudinal sectional side view of the electromagnetic brake according to the fifth embodiment of the present invention. The configuration of the electromagnetic brake of the form is the same as that of the c-type double-plate non-excited brake type (10) of Fig. 6 (4), and has an armature, a flat plate 54, a yoke, an excitation coil, a disc 51 and a spring: In the electromagnetic brake of the present embodiment, the armature, the yoke 150, the exciting coil 152, and the spring of the electromagnetic brake _ of the related art shown in Fig. 6 are used for the armature, the magnetic vehicle, the excitation, the spring, and the spring*. In the same way, as shown in Fig. 5, the electromagnet of the present embodiment is as follows: four plates of two or more pieces (two pieces shown in the figure): : Layer 55 and bonding the elastic adhesive to each flat plate to form a buffer right According to the above configuration, when the yoke releases the armature, the absorption of the electric frame, the disc, and the flat plate 5 by the collision of the eyes is absorbed, so that the impact sound when the magnetic vehicle releases the armature can be greatly reduced. 97108999 13 200914749 The electromagnetic brake of the present invention is not limited to the above various changes. The yoke form can be, for example, the agent disclosed in the above embodiment, of course, is not limited to the illustrated material. '', ;, ' In the above embodiments, the main description is to reduce the impact sound between the armature of the magnetic arm and the disc, but the buffer plate and the impact are not limited, but the caster can also be used. The plate itself, in order to make the impact sound again, in the above embodiment, you use the A 9 9 more used to release the armature's magazine 'but can also use the armature to the disc sweat ear [simplified description] (2) Other pressure-applying members of the present invention. FIG. 2 is a partial longitudinal cross-sectional side view showing the basic configuration of the electromagnetic brake according to the first embodiment of the present invention. FIG. 2 is a view for explaining the configuration of the present invention. The basic structure of the electromagnetic brake 3 is a partial longitudinal cross-sectional side view of the electromagnetic brake of the present invention. FIG. 4 is a partial longitudinal sectional side view of the electromagnetic brake of the present invention. A partial longitudinal cross-sectional side view of the present invention in the fourth embodiment. A single base is used to explain a partial longitudinal cross-sectional side view of the electromagnetic brake according to the fifth embodiment of the present invention. Longitudinal section of the technical dry-type composite plate. The structure of the dry-type θ7 is used for the topic of the electromagnetic brake of the related technology of the child. 97108999 14 200914749 The partial pattern 8 is used to illustrate the related art.
