Outer plates have a doughnut-like disk shape and are attached to the inner circumferential surface of a case member. On the other hand, inner plates have a substantially arc shape and are swingably supported about a position at a distance from the center of rotation of a shaft. The inner plates are held at a first position, at which the interlocking area between the outer plates and the inner plates is small, by a tension coil spring when the relative rotational speed between the case member and the shaft is small, and, when the relative rotational speed between the case member and the shaft exceeds a predetermined value are pivotally moved toward the outer plates by the shearing force of a viscous fluid and held at a second position at which the interlocking area between the movable plates and the first plates is large.

Torque transmission device, braking apparatus, and power transmission apparatus

Provided is a vehicle speed control device with respect to which the speed at which a centrifugal brake operates can be easily changed from the outside without disassembling the device. A brake drumis fixed to a vehicle body. A brake shoerotates around a rotary shaftof the wheel, and reduces the rotation speed of the wheelas a result of coming into contact with an inner circumferential side face of the brake drum. A springprevents contact between the brake drumand the brake shoewhen the rotation speed of the wheelis lower than or equal to a predetermined speed, and permits contact between the brake drumand the brake shoewhen the rotation speed of the wheelexceeds the predetermined speed. A position change mechanismis installed within the brake drum, and changes the position of an end of the springon one end side. A transmission mechanismtransmits a force that is input by an external operation to the position change mechanismand drives the position change mechanism.
