摘要： PROBLEM TO BE SOLVED: To provide a torque transmission device to prevent leakage of fluid through the slide contact part of a seal member as much as possible by blocking reach of fluid in a sealed space to the slide contact part of the seal member. SOLUTION: A first inertial body 2 coupled to a drive shaft 1 and a second inertia body 3 relatively rotatably supported at the first inertia body 2 are interlinked through a damper 4. A closed space 42 is formed between the first and second inertia bodies 2 and 3 and the twist damper 4 is arranged in the closed space 42 and sealed with fluid. A seal member 41 having the inner peripheral side fixed at the inertia body 3 and the outer peripheral side brought into slide contact with the first inertia body 2 is arranged in the closed space 42. A protrusion 43 positioned radially externally of the seal member 41 and protruded toward the internal part of the closed space 42 is formed on the first inertia body 2 with which the outer peripheral side of the seal member 41 makes slide contact.

摘要： PROBLEM TO BE SOLVED: To obtain optimum damping action allowing high thermal load so as to reduce structural space required for a rotational vibration damper by arranging the rotational vibration damper inside an engine casing, and holding the rotational vibration damper by a crankshaft. SOLUTION: Discs 16, 17 are fixedly connected through a spacer pin or a rivet. A connecting means of rivet shape is extended through a cutout of a damper input part 11. In this case, the cutout and connecting means are harmonized with each other so that a damping mass body 15 is capable of relative rotation, necessary for the function of a damper 10, to an input part 11. This relative rotation is limited by an energy accumulator 18 formed into a block in an advantageous form, but also limited by a spacer member coming in contact with a circumferentially adjacent end part range of the cutout. At least one flush screw can be used to reduce structural shape required for thread- connection 12.

摘要： PROBLEM TO BE SOLVED: To facilitate the control, and to prolong the lifetime of product by sealing an electroviscous fluid in a housing of a rotary system shaft, and controlling the intensity of the electric field to be applied to the electroviscous fluid so as to control the viscosity of the electroviscous fluid. SOLUTION: A rotary damper 52 is provided with a tapered rotary system shaft 521 and a housing 522, and magnetic field is applied to a magnetic reactive fluid 525 by circular magnets 523a-524b so as to seal the electroviscous fluid 523 in the housing 522. Plural electrodes, for example, four electrodes are assembled inside of the housing 522, and a different voltage is applied in the vertical direction and the right and left direction. Sedimentation of the rotary system shaft 521 is prevented and centering and change of the viscosity are optimized by applying a different voltage per each electrode. In the case where a different voltage is applied in the vertical direction and the right and left direction, particle chain of the electroviscous fluid 523 is formed, and change of the damping of viscosity due to the rotation of the rotary system shaft 521 can be controlled.

摘要： PROBLEM TO BE SOLVED: To reduce the number of part items by making the tip of a tubular part of a first rotating member come close to or contact with a second side end of a first race being fitted in an outer boundary of the tubular part of the first rotating member while a first side end is supported on the supporting part. SOLUTION: A bearing 6 is mainly composed of an inner race 13 (first race), an outer race (second race) and plural pieces of rolling elements 15. This inner race 13 is provided with a first side end 13a at the engine side, a second side end 13b at the transmission side and an inner circumferential surface 13c. The first side end 13a is supported on a supporting part 11 formed in a first flywheel 1. The inner circumferential surface 13c comes into contact with an outer circumferential surface 12b of a tubular part 12 of the first flywheel 1. With this adherence between this inner circumferential surface 13c and the tubular part 12, the inner race 13 is made so as to be relatively unrotatable to the first flywheel 1. In addition to these operations, a tip of the tubular part 12 is bent and tip of this bent part 12a is made to come close to or to contact with the second side end 13b of the inner race 13.
