A washer having such a thickness t that a value (L&#x2212;(L+L+t)) obtained by subtracting the sum of a first distance Lin an axial direction between a leading end face of a friction member and a face of a lockup piston, a second distance Lin the axial direction between a shell-side abutting face of a pump shell and a face of an outside extended portion of an output hub, and the thickness t in the axial direction of the washer, from a third distance Lin the axial direction between an opposed face of a front cover and a cover-side abutting face of a tubular portion, is in a predetermined range larger than zero, is selected and placed between the lockup piston and the outside extended portion of the output hub.

Starting device and manufacturing method of the same

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.

Centrifugal-pendulum vibration absorbing device

A damper device includes a dynamic damper that has third springs coupled to an intermediate member and that also has, as a mass body coupled to the third springs, a turbine runner and a coupling member etc. The third springs of the dynamic damper are disposed so as to overlap both in the axial and radial directions of the damper device second springs that have higher rigidity than first springs and that are disposed inward of the first springs to transfer torque between a drive member and a driven member.

Damper device and starting device

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.

Centrifugal-pendulum vibration absorbing device and order setting method for the same

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.

A damper deviceincludes a dynamic damperthat has third springs SPcoupled to an intermediate memberand that also has, as a mass body coupled to the third springs SP, a turbine runner, a coupling member, etc. The third springs SPof the dynamic damperare disposed so as to overlap both in the axial and radial directions of the damper devicesecond springs SPthat are disposed inward of the first springs SPto transfer torque between a drive memberand a driven member. A plane PL including the axes of the third springs SPand perpendicular to the axis of the damper deviceis included in the range of the thickness of spring contact portionsof the coupling memberin the axial direction of the damper device

A centrifugal-pendulum vibration absorbing device comprising having a support member coupled to a rotary element that is rotated by power from a drive device, and a mass body coupled to the support member so as to swing about a pendulum fulcrum and rotate about a center of gravity. 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 rotational angle of the mass body about the pendulum fulcrum and a rotational angle of the mass body about the center of gravity.
