摘要： PROBLEM TO BE SOLVED: To arbitrarily change a transmission gear ratio even when the error in shape is found in a valve hole by loading an OR (Oder-Glied) member and a pressure valve through an intermediate member almost without the lateral force. SOLUTION: End regions 51, 52 are formed into the spherical segment, as a result, a linear contact along a circle is generated between the end regions 51, 52 and an end region 53 formed by a conical point, of a spool hole 47, 48. When the displacement is generated between both valve spools 31, 32 and the valve hole 45 has the error in shape, the ends 51, 52 of an intermediate member 46 make the motion P to the end region 53 of the spool hole 47, 48. Whereby the lateral force does not generate on a contact part between the intermediate member and the hole wall end region 53, even when the displacement of the valve spool or the error in shape of the hole is found. Whereby a transmission ratio of a conical pulley wrapping gear can be arbitrarily and quickly adjusted.

摘要： PROBLEM TO BE SOLVED: To improve vibration damping capability by making the turning resistance of a buffer device variable for the number of revolutions or a centrifugal force, and installing a pressure accumulator effective in a peripheral direction and a friction device jointed to a flywheel mass body at the output side. SOLUTION: An intermediate plate 33 of the output part of a friction slide clutch 14 forms the input part of a buffer device 13, and the buffer device 13 has discs 26 and 45 at both sides of the intermediate plate 33. The discs 26 and 45 are connected to a rotary mass body 4 at an axial gap in such a state as incapable of turning. Also, a pressure accumulation member made of a coil spring 50 is housed in the windows 47 to 49 of the zone of the intermediate plate 33, and the coil spring 50 acts against the relative rotation of the intermediate plate 33, and the discs 26 and 45. In addition, a friction device 51 is laid between rotary mass bodies 3 and 4 in parallel with the spring 50, and at a position between the disc 26 and the zone 3a of the rotary mass body 3 in an axial direction. Thereafter, the friction device 51 is set and tightened between the disc 28 and a crimp ring 53, and a friction ring 54 is laid between the crimp ring 53 and the zone 3a in an axial direction. Also, the crimp ring 53 is peripherally fixed to the disc 26. According to this construction, a vibration can be dampened.

摘要： PROBLEM TO BE SOLVED: To improve vibration damping capability by applying the constitution that a disc part is positioned between two discs fixed to one of rotary mass bodies, and a ring disc within the peripheral zone of the disc farther from the rotary mass bodies is made to cooperate with the friction ring of the other rotary mass body. SOLUTION: An intermediate plate 33 of an output part of a friction slide clutch 14 forms the input parts of a buffer device 13, and this buffer device 13 has discs 26 and 45 at both sides of the intermediate plate 33 in such a state as incapable of turning via an axial gap and connected to a rotary mass body 4. Also, a power storage member made of a coil spring 50 is housed within windows 47 to 49 in the zone of the discs 26 and 45 as well as the intermediate plate 33. The coil spring 50 acts against a relative rotation between the intermediate plate 33 and the discs 26 and 45. Furthermore, a friction device 51 is provided between rotary mass bodies 3 and 4, and arranged in the zone 3a of the disc 26 and the rotary mass body 3 in an axial direction. In addition, the device 51 is clamped between the disc 26 and a crimp ring 53, and a friction ring 54 is laid between the crimp ring 53 and the zone 3a in an axial direction. Also, the crimp ring 53 is fixed to the disc 26 along a peripheral direction. According to this construction, a vibration can be dampened.

摘要： PROBLEM TO BE SOLVED: To increase a vibration or noise reducing effect by causing, during relative rotation of a pair of flywheel members, the spring of a first damper to act in a first angle range and the spring of a second damper to act in an angle range successive from the first angle range. SOLUTION: When a flywheel element (referred to as F.E, hereinafter) 4 is rotated from its stop position against F.E 3, a flange 41 is driven via a bayonet joint, an outer spring 45 is compressed between circumferential direction stoppers 55 and 55a and a radial direction arm part 44. When its rotation exceeds a specified relative angle range, circumferential direction stoppers 65 and 66 are contacted with an inner spring 48 and, when more relative rotation occurs between F.E 3 and 4, the spring 48 having rotational rigidity larger than that of the spring 45 and last moment larger than that of the spring 45 is compressed. Then, by the friction of the spring 45 against the surfaces of sinus parts 52 and 53 and the friction of the flange 41 against a surface 60, a friction buffering action is produced.

摘要： PROBLEM TO BE SOLVED: To increase a vibration or noise reducing effect by causing, during relative rotation of a pair of flywheel members, first and second dampers to act against the relative rotation of the flywheel members in the ranges of first and second angle ranges and partially receiving the dampers in a ring room. SOLUTION: When a flywheel element (referred to as F.E, hereinafter) 4 is rotated from its stop position against F.E 3, a flange 41 is driven via a bayonet joint and the spring 45 of the outside is compressed between circumferential direction stoppers 55 and 55a and a radial direction arm part 44. When its rotation exceeds a specified relative rotational angle, circumferential stoppers 65 and 66 are contacted with the spring 48 of the inside and, when more relative rotation occurs between the F.E 3 and 4, the spring 48 is compressed. In this case, a friction buffering action occurs because of the friction of the spring 45 against the surfaces of sinus parts 52 and 53 and the friction of the flange 41 against a surface 60, and a buffering action occurs by the swirling or displacement of a viscous medium in an annular room 30.

摘要： PROBLEM TO BE SOLVED: To enable fine regulation of a torque transmitted with a multiple plate clutch by spring-elastically forming the inner side thin plate and/or an outer side thin plate in a region engaged with a gear part. SOLUTION: In a multiple plate clutch 1, a pressure fluid led into a first pressure chamber 27 via a passage 24 also receives rotary motion. A fluid can be led into a fluid chamber 37 via a passage 35 coaxially extended to the passage 24 and a branch passage 36. The fluid used for cooling heat to be generated reaches regions of thin plates 11, 12, and 18 bypassing a flow path hole 38 in a section positioned on the radial direction inner side of an oil distributor 20 and a penetrating opening 39 in a boss 16. Rotation of the multiple plate clutch 1 generates a pressure component, which is increased by the second power of rotating speed, and the pressure component loads a diaphragm 23. A force component caused by rotation loads a piston 28, and also a thin plate unit, and as a result fine moment regulation is affected.
