<p><P>PROBLEM TO BE SOLVED: To provide a friction roller type driving device which can be obtained and used by easily changing a power chain type driving device thereto. <P>SOLUTION: In a power-and-free type trolley conveyer 101 equipped with a power rail 102 for supporting a driving element 105 and a free rail 103 for supporting a moving element 106, the friction roller type driving device 1 is changed and used from the power chain type driving device. The friction type driving device 1 comprises a supporting means 2 attached to the power rail; arms 3, 4 supported by the supporting means 2 and made to be rotatable on a carrying direction shaft C; driving means 5 and a friction roller or a backup roller 7 attached to a free end portions of the arms 3, 4; a first arm fixing means 8 coupling and fixing the arms 3, 4 while separating the rollers 6, 7 from driving surfaces 131, 132 of the moving element 106; and a second arm fixing means 9 coupling and fixing the arms 3, 4 while making the rollers 6, 7 abut on the driving surfaces 131, 132. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
