PROBLEM TO BE SOLVED: To solve problems in a conventional belt conveyer wherein a bearing part of a roller has high noise, maintenance such as grease refilling, reduction of noise, and maintenance free measures are required, and problems in an air- cushion belt conveyer wherein an air source for floating a belt is required, air jet becomes ununiform due to ununiformity of loading state of a conveyed material to contact the belt with a guide member partially, thus not only stable running of the belt is difficult but also a belt driving power varies largely. SOLUTION: A belt conveyer of the present invention aims to reduce the belt driving power, stably run the belt, and eliminate the maintenance. This belt conveyer comprises a flexible conveying belt for conveying a loaded material, a support body structure for storing and holding the flexible conveying belt, a guide member for mounting the flexible conveying belt to the inside of the support body structure, and an ultrasonic vibration device for generating ultrasonic vibration.
