<P>PROBLEM TO BE SOLVED: To provide a foamed filler for a cylindrical member capable of reducing the cost by enabling an annular foamed material to be in common while enabling a foamed amount to increase without enlarging a width size of a foamed base. <P>SOLUTION: An annular foamed material 1 having an approximately annular form is constituted by connecting a plurality of respective block parts 2, each being rectangular plate-formed and arranged in one direction with connection parts 3, and binding respective binding parts 4 connected through the connection parts 3 to the block parts 2 at the both ends. Each of the connection parts 3 is formed smaller than a width size w of an axis a direction size of the block 2 and thinner than a thickness t of a radial direction b of the annular form and allows bending deformation to approximate the respective block parts 2 facing each other across the axis a and a torsional deformation around the axis a. The connection parts 4 at the both ends connect the respective connection parts 4, and can be attached with a support member (a clip) 7 for fixing the annular foamed material 1 to the cylindrical member. <P>COPYRIGHT: (C)2012,JPO&INPIT |
