<p>When a panel (2) is vibrated in an axial direction, a viscoelastic roller (14) rotatably attached to the leading end side of a guide roller (11) is brought into elastic contact with the bottom surface of a guide groove (15) to thereby suppress the occurrence of abnormal sound. A housing-side pressure contact section (18) provided to protrude on a groove wall surface (17) is brought into pressure contact with the viscoelastic roller (14) and elastically deforms the viscoelastic roller, and a roller part (13) is pressed against a groove wall surface (16) by the elastic force of the viscoelastic roller (14), thereby preventing rattle.</p> |
