Claims

[Scope of utility model registration request]

A leg member 4, an elevating member 6 supported by the leg member 4 so as to be able to rise and fall, a gas spring 8 for applying an elastic force upward to the elevating member 6; In the elevating table equipped with a flake mechanism that is releasably fixed to the member 4, a pedestal 50 is fixed to one of the leg members 4 and the elevating member 6, and a roller 56 is attached to the pedestal 50. It is rotatably supported so that its surface comes into elastic contact with the wall surface of the other of the two members, and one side of at least one transfer piece 68 is rotatably supported on the side surface of the roller 56. An eccentric cam portion 74 is formed around the shaft support of the piece 68, and a position away from the shaft support of the rolling piece 68 is set at a position apart from the shaft support so that the rolling piece 68 does not protrude outward from the outer peripheral edge of the roller 56. The roller 56 is still in contact with the contact surface provided on the roller 56 with a predetermined urging force, and as the lifting member 6 suddenly falls, the roller 56 rotates rapidly and the centrifugal force causes the transfer piece 68 to resist the urging force and move When separated from the contact surface, the eccentric force is applied so that the large eccentric portion of the eccentric cam portion 74 of the transfer piece 68 sinks into the wall surface of the other of the two members. A safety device characterized by: (2) the shape of the arm portion 74 is set;
