摘要： A four-bar linkage vibration absorbing device includes: crank members each coupled to a driven member of a damper device via a coupling shaft and each capable of swinging about the coupling shaft when the driven member is rotated; and a mass body that is coupled to the driven member via the crank members and that swings about the rotation center RC together with the crank members when the driven member is rotated. The driven member is coupled to a turbine runner of a hydraulic transmission device so as to rotate with the turbine runner.

摘要： A cushioning member between plate bodies of a mass body and at end portions, in the circumferential direction, so as not to rotate relative to the plate bodies. The peripheral edges, on both sides in the width direction, of the outer peripheral surfaces of the cushioning member's first and second side portions abutting against a support member, along with swing of the mass body, are chamfered, reducing the possibility that the cushioning member enters in a clearance between the side surfaces of the support member and the plate bodies when the cushioning members' first side portion and the support member abut, or when the cushioning member's second side portion and the support member abut, along with swing of the mass body, suppressing damage to the cushioning member.

摘要： A damper device includes first inner springs configured to transmit a torque between a drive member and an intermediate member, second inner springs configured to transmit a torque between the intermediate member and a driven member, and a rotary inertia mass damper including a sun gear serving as a mass body rotating with relative rotation of the drive member to the driven member. The rotary inertia mass damper is provided in parallel to a torque transmission path including the intermediate member, the first inner springs and the second inner springs. A damping ratio ζ of the intermediate member determined based on a moment of inertia J2 of the intermediate member and rigidities k1 and k2 of the first and the second inner springs and is less than a value.

摘要： A coil spring is formed by winding a wire in a coil shape. In the cross sectional shape of the wire formed in the coil shape, the inner diameter side part in the coil shape includes a semi-elliptical shape having a major radius and a minor radius and the outer diameter side part in the coil shape includes a curved shape circumscribing a circumscribed circle having a radius larger than the minor radius, arc shapes having a curvature larger than the curvature of the circumscribed circle, and linear shapes connecting both ends of the arc shapes to both ends of the semi-elliptical shape. This can increase the cross sectional shape of the wire, reduce a shearing stress, and improve the durability of the coil spring.

摘要： A centrifugal-pendulum vibration absorbing device disposed within a liquid chamber that stores a liquid, the centrifugal-pendulum vibration absorbing device having a support member coupled to a rotary element that is rotated by power from a drive device; and a mass body supported by the support member so as to be swingable. An order of vibration of the mass body is determined on the basis of an order of vibration to be damped generated by the drive device in consideration of at least a force caused by a centrifugal liquid pressure generated within the liquid chamber along with rotation of the drive device to act on the mass body.

摘要： An intermediate member of a damper device includes a plate portion that has spring abutment portions that abut against inner springs. Spring abutment portions of a coupling member of a dynamic damper extend from a fixed portion via a bent portion to be disposed in opening portions of the plate portion, and abut against end portions of third springs disposed in the opening portions such that the third springs are arranged side by side with the inner springs in the circumferential direction. The plate portion and the spring abutment portions at least partially overlap each other in the thickness direction. The axes of the inner springs and the third springs are included within the range of overlap between the plate portion and the spring abutment portions in the thickness direction.
