Claims

[Scope of utility model registration request]

A torso body whose end shafts are supported by frames on both sides,
a pair of support members located inside the frame and supported by the respective end shafts; and a shaft member that axially penetrates the outer circumferential space of the trunk body and is supported between the support members on both sides. In a sheet-fed printing machine with a reversing mechanism having a plurality of suction members arranged in parallel with each other, the support members on both sides are rotatably fitted to the both end shafts, and the plane thereof is aligned with the cylinder. A shaft attached to the end surface of the main body, having a head at one end and a threaded portion at the other end is provided passing through the central shaft hole between the main body and the shaft at both ends, and the base of the shaft at both ends has a diameter. A fixing member is provided that penetrates in the direction and is attached to the end surface of the supporting member opposite to the barrel main body, and moves by screwing the threaded member into the threaded portion to fix the supporting member and the barrel main body by surface pressure. A sheet-fed printing machine with a reversing mechanism, characterized in that a deflection deformation absorbing member for the fixing member is interposed between the joining surfaces of the fixing member and the supporting member by fitting a convex arc surface and a concave arc surface. Adsorption member fixing device.
