外表面に硬質ゴム層４が巻き付けられて構成されるのが
一般的である。<Prior Art> Conventionally, as shown in FIG. 5, in a printing support roller of a typewriter or a computer printer, a metal tube 1 is attached to a presser metal fitting 3 supported by a roller shaft 2, and the outer surface of the roller is attached to a metal tube 1. Generally, a hard rubber layer 4 is wrapped around the surface.
この金属管１としては、消音機能を保持させるべく例え

材としたものが知られている。しかし、上記のような金
属管を使用しても消音ｌ！能が十分ではないため、新た
な騒音防止対策が要請されている。Known examples of the metal tube 1 include double tubes made of lead or mild steel, and tubes made of aluminum alloy, for example, in order to maintain a silencing function. However, even if you use a metal tube like the one above, there is no sound! new noise prevention measures are required.
このような騒音防止の要請に対応する手段の一つとして

制振鋼板を円形状にした鋼管を製作しようとの試みがな
されている。As one of the means to meet such demands for noise prevention, the use of damping steel plates, which are said to have high damping properties, has recently been attracting attention. This damping steel plate is made by interposing a viscoelastic resin as an intermediate layer between steel plates such as mild steel in a sand inch shape, and absorbs vibration energy through the sliding deformation of the viscoelastic resin due to bending vibrations received on its surface. It converts into thermal energy to exhibit a vibration damping effect, and attempts have been made to manufacture steel pipes using circular damping steel plates.

うことになる。That is, when a conventionally known high-frequency welding method is used as a welding means for the butt portion, for example, as shown in FIG.
When the vibration-damping steel plate 5 with 6 interposed therein is formed into a circular shape and the side edges 7 and 8 are subjected to high-frequency heating via the contactor 9, the side edges 7 and 8 become uniform in the thickness direction. heat effect tI heated as

できないなどの問題がある。In addition, even if continuous welding is attempted using micro TIG welding, which uses a small current and has a small thermal effect, the resin directly under the weld will still melt and generate gas, and the gas will blow out and the weld will be damaged. There are problems such as the molten pool being destroyed and welding not being possible.
