Description of the Invention: [Technical Field] The present invention relates to a method in which a movable portion and a connecting portion are braked and driven by a rotation drive connecting portion from a non-nine function;欢处# The electromagnetic connection device factory of the driving state of the moving part or the transmission of the rotating drive [prior art] The far-thoughts can be borrowed; the 5z function is replaced by the non-connected state and the == drive unit and the link part can be switched The electromagnetic connection device of the company is an electromagnetic brake that can be used for movement, and can transmit the rotation of the rotation:: to the electromagnetic clutch on the side of the connection portion. In the case of an electromagnetic brake, for example, a disc, a plate, an armature, and a helix: a magnetic actuator is driven by a shaft and a disk drive, and is formed on the surface. The round face material can be rotated with the shaft: the number has been increased, and the rJ coil spring can give the armature a potential r and press it against the 0 disk. Electromagnets Beer-potential - The coil spring gives the potential #, the force acts against it. The electromagnetic device described above: the armature is liberated from the electromagnet by the heat of the electric motor without supplying heat to the electromagnet, and the disc is clamped to the steam plate of the fish plate by the potential energy. A disc is caught between the discs. Therefore, it is wrong to be braked by the torque of the disc and the friction of the armature and the plate 201004108. When the iron is supplied with electric current, the electromagnetic disc is formed to be freely rotatable between the disc and the iron disc. In view of the above-mentioned electromagnetic connection noise, the release action may be used as a connection between the 敎 % = 技 技 技 = = = = ^ ^ ^ ^ ^ 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在Therefore, the impact sound of τ ^ 4 can be used under the limitation of _ sound < s. For example::, the material of the sputum, and the patented text of the L-Budan iron plate cutting steel plate (see, for example, the electromagnetic connection of the connection of the electromagnet, the description of the electromagnet) With the rotating drive unit and the electromagnetic cymbal, even if the connecting portion has been constructed as a laminate, r_ _ 妾, the impact force generated at this time is absorbed by the # ^ buffering effect, and the joint % < Therefore, a: and the impact noise generated by the squad. The slab-shaped cushioning material or the rubber-like cushioning material or the rubber sheet is proposed. Consolidation and integration of the outer periphery of the yoke and the sheet 2). Secondly, the holes are provided in the outer peripheral portion of the assembly of the holes, and the above-mentioned respective holes are formed. According to 1:::: When the gap between the sheets is maintained as an electromagnetic connection device that acts on the connection portion, the connection portion is absorbed by the cushioning material, so that the impact noise generated when the ink is transferred by the fourth drive can be reduced. 201004108 Patent Document 2:曰本特开平=181号, however, the patent document is ^^^^^ When the report unit is placed in the vicinity of the rotation drive, the connection is set to the moment, and the connection unit is integrated: the ΓΓ drive unit transmits the member that the contact member is in contact with the drive unit after the connection, and the rotation is described above. The member that is in contact with the rotary drive unit emits::: turn:: for the member that has not been in contact with the above-mentioned untouched structure, the above-mentioned bolt is subjected to a large amount of the object, and the hole for the self-assembly thread is penetrated. : Injury and stress concentration on the group 褒 consider the strong joint of the joint on Tuesday:: 砀. Here, you can also form a body, or W '+ σ to make the layers of the components closer to increase the strength of the thick side of the component, or improve , and can not effectively reduce the impact: the second 'integral rigidity will be [invention] design, can provide a kind, and avoid the junction of the joint is switched into a joint shape. The present invention is contrary to the above problem and the electromagnetic connecting device can be suppressed In addition to the impact noise, the rotary drive unit can be connected to the 'state and the non-connected state. In order to solve the above problem, the electromagnetic connection 6 ^uiuu41U8 of the present invention can be rotated forward to the predetermined portion. In the opposite direction: "the driving direction is substantially orthogonal to the magnetic force, and the front: 丄 and the switching mechanism can be connected to each other by means of electrical connection: = the rotary drive unit is switched so that the connection portion contains at least Non-connected state: the number of advances and retreats: the non-consolidated state is laminated on at least one of the front members and the like: a member, adjacent to the plate-like surface, which is provided with a restriction on the other side The wiping limit of the plate-shaped member in the direction of the moving direction: the state in which the plate-like member of the other side faces the rotating-discharge layer includes a degree of forming a gap in the advancing and retracting direction: it can be disposed between the plate-like members Advance and retreat action. The structure is independent of each other and can be described as a structure. When the rotary drive unit is switched to the connected state by the switching mechanism, the connection (2) is mutually advanced: the state advances and retreats, and the phase: the second consolidation state Therefore, it is not possible to form a gap between the plate members in the above-mentioned manner: 3, the downward direction and the advance and retreat directions are independent of each other:

Therefore, it is possible to protect the redness of the A-Yi-Yi-Yi-Yi-Yi-Yi-Yi-Yu-Yu-Yu-Yu-Yu-Yu-Yu-Yu-Yu-Yu-Yu The rough anti-external force is used to avoid damage, and the rubbing restricting portion may be a friction surface. According to the above configuration, the rubbing force generated by the U-plate J_, the shape 谌 MW... and the plate-like member of the other side can limit the rubbing toward the rotational driving direction 201004108. Therefore, the grievances and the reinstatement are not damaging. The plate-shaped member that can form the adjacent rebel member can be restrained from the external force to avoid the eight, and the invention preferably includes the armature, and the plate is substantially plate-shaped in the first two; The direction is entered in the direction of the direction separation, and is set to be made in the aforementioned 彳 & The description of the number of the rotary drive units is described as the above-described connection portion. The structure can be switched to a plate and a contact with the switch mechanism. The wheel includes a plurality of plate members. As the connecting portion, there is a moving portion. Therefore, the armature is in the direction of the connecting wound, and the body is opposed to the external force to avoid the impact when the noise-reducing driving portion and other members are in contact with each other. Both the sheet and the armature preferably include a plurality of plate-like members as the connecting portion. According to the above configuration, both the plate and the armature include the plate-like member 4 as the joint portion, so that the external force can be integrally prevented in the rotational driving direction to avoid damage and the impact noise can be more effectively reduced. 201004108 Further, in the switching mechanism, the connecting portion faces the forward and backward side, and the biasing member can apply the potential energy to the front magnet by the electromagnetic force; and the other side of the connecting portion: On the side, each of the electromagnets of the connecting portion is set to be smaller than the biasing member: the electromagnetic force acting on the plate-like member is preferably a force 'and a force acting on all of the biasing members.

In addition, it can be: the state of the money or the state of the unconnected state. In::,: The hunting electromagnet exerts an electromagnetic force on the joint portion and is a magnetic force; the electric function of each plate member of the joint, ', and port # is less than the force of the above-mentioned fusible member. Therefore, even if the missing components are in the phase-bonded state, it is also possible to avoid only - and :: the plate-like members are separated from the other plate-like members against the dominating force: :::! lead. Secondly, the force of the power of all the plate-shaped members is set to be greater than the force of the ortho-conducting members. The plurality of plate-like members constituting the connecting portion can be used as an electromagnet against the empowerment of the orogenic armor. Attracted, and or, the other state of the knot state. Therefore, it is possible to effectively reduce the wood day, and the sub-members of the Xin-like plate are separated by the electromagnetic force and are spliced by the driving part. 10 201004108 Further, the electromagnetic force acting on any of the plate-shaped members by the electromagnet is the other The force of the above-mentioned potential member is less than the above-mentioned configuration according to the above-mentioned structure, and the electromagnetic force of the action of the combined force α^ and the plate-like member is sighed with respect to the positional force of the m-member other than the one-piece. When the 疋 杈 is small, the electromagnetic force can be used to prevent the separation of the joint portion, and the body can be attracted.

In the fixing hole 43b, a substantially axial guide member 45 is fixed substantially in parallel with the rotation axis L. The leading end portion of the guiding member 45 protrudes from the magnetic light 43 toward the side of the sheet 20. The leading end portion of the guiding member 45 is formed through the guide plates I 4 holes 3iC, _ formed in the respective plate-like members 31 and the plates 2 of the armature 30, respectively. Further, the leading end side of the guiding member 45 has a segment portion ba and the portion 4a reduces the diameter thereof. Further, the guide member 4 has a male thread formed on the end side thereof and a nut outer screw right member 45 in the male screw thread, between the segment portion 45a and the nut 45b, and 4 members 46° plate 2G Then, between the heads 45b of the spring members 46 (4), the soft plugs are inserted into the basins. The plate 20 can be elastically clamped by the potential energy. The plate 20 can be held substantially in one piece with the yoke 43 and can be rotated. The plate members 31 can travel along the guide arch I I (4) as the Hi member 45. A single, flat, lower, is provided in the circumferential direction. Ren Qianbian's inspection. One end side of the retractable bomb yellow 42 is placed = the end face 43 of the opposite side. The upper f is placed in contact with the electric hug 30. So he ends up towards the disc 1. The side gives potential energy. In addition, "2 can hold the electric 30" "other brother - in the figure, the spiral magazine 201004108 42 is illustrated as having a single, but in the plane view, in the circumferential direction. Secondly, as shown in the first figure, a current is applied to the coil 44 of the electric=iron 41: ::: a magnetic force acts against the auger 42; From the face of the disc 1〇: 2: Hunting this 'can make the electric (four) connected state as the first piece of knife is separated and the coil of magnetic light 41 is "input current and 仏 = magnet is not affected by electromagnetic force, so The iron (4)-plate member 31 can be used to form a pair of disc members. The facing member 13 is crimped: the force is formed to form the plate members of the armature 30. The degree is set to make the sum of the force of the electromagnetic spring 42, the force of the force smaller than the electromagnetic force of the screw 31 is greater than the sum of the snails: the plate-like member of the slab. ' « ί 如 如 τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 The armature 41 is formed. The pivot 30 can be used against the spiral bomb. ^: With the electromagnetic force, the side of the electric coil spring 42 is formed and the force is attracted to the snail state. Therefore, the disc 1〇 will be formed at !^^43c Abuts the non-connected state with a gap, and rotates between the 30 and the plate 20. The rotation of the sub-rod 2 is 17041 08 In addition, when the brake shaft 2 and the disc 1 are rotated, the switch 4 is switched, and the coil 44 of the electromagnet 41 is stopped from being supplied to the state of being unexcited. Electric: Rotation: 3〇 will be in the direction of the L axis due to the potential energy given by the coil spring 42; ^Main ji] drag _ ^ η μ & 芊 而 and the media cuckoo move. Therefore, the facing member of the disc 10 13 will form a connected state between the plate 2 and the armature. Therefore, in the shaft 2 and the disk, the material of the surface member 13 is smashed by the armature 30 and is braked by the armature 30. 2〇 and solid 4: The plate-like members constituting the plurality of armatures 30 are not sad, and it is also possible to suppress the restraining force from being generated in the shape of the rotation axis to the 丨, and the state of the father is half-light. It can especially suppress the impact generated when the end face of the heart has been lowered, and the rush is generated when the end face is abutted; „41 makes the case of the magnetic car illusion, and effectively reduces the ratio of the high-frequency component of the noise level to 20 R, and the disc 10, the cup y and the armature 30 contact decoration: the thickness of the reverse sheet member U, then the weight of the afternoon is greater than this, more effectively reducing the impact noise. Further, by the spiral magazine 42 > @ disc (3), the joint potential energy is repeatedly formed so that the rotational force of the pair of electric locks 30 in the rotational driving direction is restricted from rotating from the disc 1 to the W member 45. S ' sub-electrogram 30 acts ' and the self-guided '5 toward the rotation drive: move:. Therefore, the reaction force will act in the direction of . Here, the armature 18 201004108 = is pressed against the disk ι , and a frictional force is generated between the plate-shaped members w of the armature 3 and the like in the above-described rotational driving direction. However, the opposing portion 31b of the member 31 is provided with the engaging portion 32 forming the radial concavities and convexities in the radial direction, so that the restraining force can be effectively generated in the rotational driving direction which is substantially orthogonal to the radial direction, thereby restricting mutual rubbing. move? Therefore, after the disc 10 is crimped to the armature 30, even if the external force acts as the above-mentioned cymbal in the rotational driving direction, the plurality of plate-like members 3ι can be one or two, which can avoid the plate which is in direct contact with the disc 1〇; The plate member 31 which is not in contact with the disk 10 is rubbed to abut against the guide 2 45, so that the stress is concentrated near the guide hole ^ of the plate (four) member 31 of the disk, resulting in a damage like 10' Reverting to the non-connected state, and making the shaft 2 and the circle 钇蚪, the switching mechanism 40, the electromagnet ring 44 is connected to the Leihu, the warehouse, and the wind body; In the magnetic field, the magnetic plate, each of the plate-like members 31 is subjected to electromagnetic force as the plate-like member 31, and is attracted to the coil spring 42 to be magnetized. 21# Here, each of the plate-like members 31 constituting the armature 3? The sum of the force of the f μ + coil spring 42 acting on each of the plate-like members 31 is thicker and further. ::^ will not cause the anti-helical" member of the wrench member 31 to separate; 4^ potential energy from the other plate-like pairs of all the plate-like members 31, because the force of the rotary spring 42 can be made "the combined force of the force is greater than the snail The plate member 31 can be attracted to the electromagnet 41 by the force of the body. 19 201004108 /, the plate-shaped 10 of the integrated armature 3 is separated and guided by the guide arm I member 45, the disk ', U will abut from the disk 43c to form a non-connected can The end surface of the yoke 43 is larger than the thickness of the plate 20 and the electric shuttle. The disc 10 will be formed at a distance of -, and the electric weight d0 will be formed by the sister to form a state corresponding to the shaft 2, and rotated to rotate. State. Non-two: The plate-like member 31 constituting the plurality of armatures 30 is also in an unconsolidated state, so even if the electric member 31 is in a state, it can be held by the corpus callosum to maintain the overall rigidity. Can effectively reduce the sorrow of the electromagnet 41 3^. As shown in the above, the armatures are separated and independent (4), and the material 1 U will not be sucked by the electromagnets!

In the above-mentioned electromagnetic brake 16〇, when the non-connected state is changed to the two-state, the plate 161 will also be pressed against the disk 11 and will be punched with 4 sounds. 'But the plate 161 also has a plurality of plate-like members laminated structure. Therefore, the reduction of impact noise can be achieved. Further, each of the plate members 162 of the plate 2 is also provided with the engaging portion 166, so that the effect of preventing the two injuries can be prevented in the same period 201004108. In addition, the plate 161 is elastically clamped by the clamping mechanism 165, so the plate member 162 can resist the clamping force of the clamping member 146, and can advance and retreat independently toward the direction of the screw, and can further form a body. status. Therefore, in the state of the three junctions, the noise in the plate member 162 can be more surely avoided: it is wiped off from the disk UQ, and the wiping sound is generated in the plate member 162 or the like in the f 'plate #161. At least the peripheral portion 162b is a non-solid gentleman, this & _ mouth sorrow. In addition, in the above description, although it is the structure of the electrical tow layer of the connection part, and the electric energy is $#, it is explained, but only the plate-layer structure is used for the punching plate: The damage caused by external force, and the effect of reducing the impact noise. 1 Shoulder Bamboo (Different Case) 俜作: This is explained in the second embodiment of this winter. The seventh figure shows the operation of the second embodiment of the present invention, and corresponds to the above-mentioned reference numeral 'and the description thereof is omitted: the member will adopt the number of the number: the seventh circle is not the same as the embodiment. Electromagnetism in the electromagnet of the switching mechanism 240, such as 270 in the opposite end face 243c = H magnetic face 243 and the inner circumference of the electric _ _ 恻 = = 24 201004108, the electromagnetic brake 27 本, the circle The disc 1 includes a first facing member 213 (a facing member of the first embodiment). At the same time, the surface of the armature 230 opposite to the disk 21〇 and the plate 22〇 are aligned with the disk 2 1 to the A (1) and 272 components. -It;: not highlighting the second veneer to form an annular shape, and projecting two; ... 272 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The second facing member η 2 is protruded so that when the electromagnet 241 is in an unexcited state 2 and the non-connected state is switched to the connected state, before the plates 220 and 21 are attached to the 213, the circle is first The disk member 212 abuts. Further, a material of the elastic modulus 胤hi 213 of the material of the second facing member "71, 272 is formed. 卞" is formed in the electric shaft actuator (4) of the embodiment of the first facing member, and the electric quantity = f magnetic The state is switched from the connected state to the non-connected state. (4) The cage 242 £ 230 is attracted by the electromagnet 241, and is biased against the screw. The force is applied to the end face 24 of the yoke 243 against the end face 243 of the yoke 243. A concave portion 243e is formed on the surface 243c, and the magnetic yoke is abutted on the end surface 243c outside the concave portion (10), and is supported by the magnetic vehicle 243 of the electromagnet 241 in a beam shape. Therefore, when it is lightning, it will abut. The part is a fulcrum, and the deflection is performed within the range in which the plaque 243 abuts. Therefore, the impact = 24 (four) direction can be more effectively reduced. The erection is absorbed in the 哗%%. In particular, the recess 243e is set at 25 201004108 Then, the armature 230 is formed in a state in which it is fixed from the inner circumferential side toward the outer circumferential side, and the amount of the bending is further increased, and the impact noise is effectively reduced. Minor. After this, due to the deflection of the armature 230, even if it is also abutted after 2, to It can absorb one part of the impact energy, and can expect the effect of the impact noise reduction. 'Monthly another', once the electromagnet 241 is in an unexcited state, it is switched from the non-connected state to the far surname. At α 〇 逑 逑 逑 状Then, the armature 230 will be moved sideways by the force of one of the spirals toward the rotating shaft L. The disk 2 is sandwiched between the plate 220 and the armature 230. Before the drag 230 is attached to each of the first facing members 213 of the disc 210, the face member 271, 272 of the coin-shaped member will be attached to the material of the first member (7), 272. The second veneer structure ^ ^ _, early 1' birth rate is smaller than the first veneer member 213. The two veneer members 271, 272 can be more flexibly: wide. Therefore, the disc 21 can be impacted by a small impact. The second member 213 abuts the plate and moves to the armature 23 因此. Therefore, the slab Si 220 and the electric yoke 230 are connected to the disk 210 to be nr. 'In the example', the second facing member 27 Although the shape of the 272 is not limited to this, it may be set to a variety of brothers in the position of the rotating shaft, the shape of the first piece 213, and the position of the first platinum. The surface members 271 and 272 are provided on the plate 22〇201004108^the armature 230i, but are not limited thereto. The magnetic brake 280, the second facing member 281, as shown in the eighth figure, 282 can also be disposed on the body member 212 of the disc 210, and abuts against the opposite direction 220 and the armature 23A. Further, although the corresponding piece 22 〇 and " ' 2 3 0 and the second decoration The surface member is not limited thereto, and may be provided corresponding to either one. In the first to third embodiments of x and the modifications thereof, etc., the electromagnetic brake of the non-excitation type is exemplified as the electromagnetic connection = "but" but is not limited thereto. The present invention can also be applied to an electromagnetically actuated electromagnetic brake that can be connected to a 4 m twisting drive unit in a connected state after the electromagnet is excited. (Fourth Embodiment) The fourth embodiment will not be described. Ninth and I::: shows a fourth embodiment of the present invention, which is an example in which an electromagnetic clutch for exciting is used as an electromagnetic connecting device. The electromagnetic clutch package of the present embodiment is shown in the figure: =. , hub 32 〇, armature 33 〇 'switching mechanism - : with 30: rotary drive. The trough 32 〇 is matched with the disc training = the second pivot 330 system is set at the disc 31〇 and the turret. Connected with ',, Q#. The switching mechanism 340 can switch the power to disconnect the connection state and separate the 31 0 system. Disc 3〇1, clothing: active side and rotatably driven first-axis identical member. The disk 310 includes a 27 201004108 body member 311' having a flange portion a and a facing member 312 attached to a surface of the flange portion 311a opposed to the hub 32A. In the main body member 311 of the disk 31, the cylindrical portion 311] which protrudes from the flange portion 311a is externally fitted to the first shaft 301 and fixed. Therefore, the disk 31〇 can be rotated coaxially with the rotation axis L of the first axis plus one. The material and shape of the facing member 312 are the same as those of the facing member of the first embodiment, and the description thereof will be omitted. Further, the wheel breaking 320 is attached to a substantially ^-shaped member which is connected to the driven side and is rotatable on the coaxial shaft L of the rotating shaft L. The hub 32 is opposed to the armature 33A and is provided with a flange portion 320a. Further, the armature 330 is composed of a plurality of plate-like members 331 and 332 which are substantially disk-shaped and composed of a magnetic body. A plurality of plates: members 33 and 332 are laminated on each other in an unconsolidated state. In the same manner as in the first embodiment, the engaging faces 331a and 332a of the plate-like members 331 and 332 are formed with a concave portion formed by a radial unevenness around the rotating shaft B. Motion limiter. Further, the wiping restricting portion is not limited to the engaging portion, and may be a friction surface temple. Further, in the present embodiment, the electric tow 3 (four) is constituted by the two-layered plate-like members 33 332, but may be three or more layers. The switching mechanism 340 includes a flange portion "n = an electromagnet 34i opposite to the armature 33G", and an armature 330 is disposed between the armature 330 and the hub 32? The electromagnet 341 includes a substantially cylindrical yoke 343 28 201004108. The electromagnet 341 is externally mounted so as to be rotatable by the rotation of the bearing 345 and ==: r311b. The piece h 3 4 2 is rotated. The shaft L is placed at the center with a number of turns. Each leaf spring 342 ° is fixed to the rivet 342a and is fixed 33 〇, ~ 32 〇 ±, and the other end is fixed to the electric plug by the rivet 342b. Here, in the plate-like member 331 constituting the armature 330, the plate-shaped member 33 on the hub 320 side is formed with a through hole 3 in the corresponding plate spring 342. The leaf spring 342 is fixed. The closest plate-shaped member commits 2. On the other hand, the plate spring 342 can serve the potential energy to the hub 32 and suck the electrode. Therefore, the armature 330 is not energized by the current flowing through the coil 344 of the electromagnet 341. In the state, the electromagnetic force is not applied, and the flange portion 320a of the hub 320 is brought into contact with each other due to the biasing force of the leaf spring 342. The function of the present embodiment is explained based on the ninth and tenth views. As shown in the ninth figure, the armature 330 will be given by the leaf spring 342 in the unexcited state of the electromagnet 341 of the switching mechanism 34 It is in a state of abutting against the hub 32A, that is, in a non-connected state from the disc 310 77. Therefore, the rotation of the first shaft 3 〇1 and the disc 310 will not be transmitted to the armature 33〇, The hub 32 is coupled to the second shaft 302. When the rotation of the first shaft 301 is to be transmitted to the second shaft 3〇2, the switching mechanism 340 turns on the current of the coil 344 of the electromagnet 341 through 29 201004108. Excitation, the magnetic field will be generated, and the plate-like members 331, 332 of the electric frame 330 formed by the magnetic body will be subjected to electromagnetic force. At this time, as shown in the tenth figure, the plate-like members 33, 332 will oppose the plate. The biasing force of the spring 342 is attracted to the yoke side, and the facing member 312 of the disc 310 is crimped to form a joint shape. Therefore, the rotation of the first shaft 301 will pass through the armature 330 from the disc 3, The hub 320 is transmitted to the second shaft 3〇2, and the second shaft 3〇2 is rotated about the rotation axis L. At this time, Since the pivot 330 is a laminated structure of a plurality of plate-like members 33 and 332 in a non-consolidated state, it is possible to suppress the mutual restraining force in the radial direction orthogonal to the direction of the rotation axis L, and to maintain the overall rigidity. The ratio of the high-frequency component of the impact noise of the pivot 33〇 to the disk 31 is effectively reduced by the level of the dull level. Further, the supply of current to the electromagnet 341 is stopped to form the state of the excitation, and the armature 33 is set. The same applies to the case where the disk 31 is switched from the connected state to the non-connected state, and the noise level when the armature 33 is abutted against the hub 320 can be effectively reduced. Further, when the armature 33 is placed in the connected state by the attraction of the electromagnet 341, the external force acts on the electric axis 3 from the disk 31 to the rotation axis L in the (four) driving direction. And the reaction force will also act from the plate bomb I 342. Here, as described above, the plate-like members 331, 332 of the armature 330 are provided with the engaging portions to effectively generate the frictional force in the rotational driving direction. Since 30 201004108, the plate-like members 33 332 can be integrally opposed to each other even in the 'driving direction' in the rotational driving direction, and the damage is prevented from occurring at the position where the stress collecting plate is restrained. In the eighth embodiment, an electromagnetic exciter of the electromagnetic actuating type is exemplified as an electromagnetic connecting device. The electromagnetic clutch can also be applied to the present invention. The above-mentioned embodiments of the present invention have been described, but the specific configuration is not limited to the above-described design changes and the like.歹 亦 亦 【 简单 简单 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第The second figure is a cross-sectional view of the banded state of the first embodiment of the present invention.
