<p>PROBLEM TO BE SOLVED: To provide a motor roller which is used for laying cables and for which a rubber lining which comes into contact with cables can be exchanged easily. SOLUTION: The case of a motor roller is built in a double structure. That is, the motor roller is provided with a motor 4, a cylindrical case 3 which is rotated by means of the motor 4, a cylindrical drum 2 which can be attached to and detached from the outer periphery of the case 3, and a rubber lining layer 8 which covers the outer periphery of the drum 2. Since the drum 2 is attached to the case 3 with bolts 10, the drum 2 can be removed easily from the case 3 and the drum 2 and rubber lining layer 8 united with the drum 2 in one body can be exchanged with new ones when the bolts 10 are removed.</p> |
