Claims

[Claims for Utility Model Registration] Four portions are formed on the inner circumferential side of the inertial mass having a generally annular shape and are open radially inward and continuous in the circumferential direction, and are coaxial with the inertial mass green. The peripheral edge of the approximately disk-shaped mounting plate is inserted into the recess, and an annular rubber body is inserted between the inner wall surface near the opening of the recess and the front and back surfaces of the mounting plate, respectively, so that the inertial mass is These rubber bodies elastically connect the mounting plate and the inertial mass body, and furthermore, the gap between the innermost part of the recess and the periphery of the mounting plate is filled with viscous material. In a damper for torsional vibration prevention filled with fluid, the inertial mass body is constituted by a pair of annular divided pieces 1 facing each other at a constant interval on each of the front and back surfaces near the peripheral edge of the mounting plate, and On the outer circumferential surface of the divided piece, an annular connecting piece is formed by bending a thin plate band member into an annular shape, welding its ends together, and forming a small hole or a small recess at a position near both ends of the welded part. , and by bending both side edges of the connecting piece toward the inner circumferential side at the position of the small hole or small recess, the connecting piece is caulked to the two split pieces, and the connecting piece connects the two annular shapes. A damper characterized by connecting and integrating divided pieces.
