Abstract: The flywheel assembly for transmitting torque from the crankshaft 191 of the engine has a second flywheel 103, a damper mechanism 104 and a support member 119. The damper mechanism 104 elastically connects the second flywheel 103 to the crankshaft 191 in the rotational direction. The support member 119 supports and positions the second flywheel 103 on the crankshaft 191 in the radial direction.

Abstract: A damper mechanism 6 is provided to transmit torque while absorbing and damping torsional vibrations. A small coil spring 45 achieves characteristics of a low rigidity in a small torsion angle region of the torsion characteristics when compressed by rotary members. A coil spring 33 achieves characteristics of a high rigidity in a large torsion angle region of the torsion characteristics when compressed by the rotary members rotating relatively to each other. A frictional resistance generating mechanism 7 generates a frictional resistance while each spring is being compressed. Owing to a rotating-direction space 79, the frictional resistance generating mechanism 7 does not operate in the second stage of the torsion characteristics and also does not in the first stage while a torsion angle is in a predetermined range.

Abstract: A power coupling mechanism includes a flexible disk-like plate, a ring element, first and second input plates and a driven plate. The ring element is coupled to an outer radial portion of the flexible plate. The input plates are formed of deformed sheet metal material to at least partially define a viscous fluid filled chamber that encloses a dampening mechanism. The input plates are fixed to the ring element and the flexible plate such that center and inner radial portions of the flexible plate are axially spaced from the input plates to permit axial flexing. The driven plate at least partially extends into an annular housing of the dampening mechanism and has grooves interfitting with protrusions of the annular housing to provide structural support against thrust and radial forces. An inertia element with a ring gear is preferably connected to the driven plate.

Abstract: A flywheel assembly comprises a flywheel having a friction surface, a flexible plate, and a stopper plate serving as a stopper mechanism. The above-described flexible plate is flexible in the bending direction and rigid in the rotational direction, and has a radially outer portion fixed to the flywheel and a radially inner portion fixable to an end of a crankshaft of an engine. The stopper plate is for restraining bending deflection of the flexible plate when it exceeds a predetermined amount.

Abstract: A pan head mounting head of a tripod for photo and VTR cameras in which a single pan rod for swinging and shifting the pan head to the photographing direction is provided, and by changing the degree of clamping of this rod, the vertical swing movement or both the vertical and horizontal swing movements can be locked.
