A device for regulating swing resistance of swingable devices such as video cameras and/or motion picture cameras. A pair of right and left shoe members to be fixed to the swingable device are mounted on the body side. Elastic O rings are commonly fitted in the peripheral surfaces of the pair of shoe members and disposed such that the O rings can be contacted with and separated from the inner peripheral surface of a back plate filled with a viscous member. The contacting state of the O rings with the inner peripheral surface of the back plate is changed from a line contact to a plane contact by adjusting operation of a control member for spreading the pair of shoe members in order to steplessly regulate a swing resistance.
