PROBLEM TO BE SOLVED: To provide a lateral sealing device of a packaging machine, which can supply power to both electrodes of each of a plurality of vibrating elements from a non-rotation side in an inexpensive method.SOLUTION: In a lateral sealing mechanism 17, a cylindrical film Fm is sandwiched and ultrasonic sealing is performed along a direction that intersects a conveying direction while a first horn 51a and a first anvil 51b, and a second horn 52b and a second anvil 52a rotate. The first horn 51a is mounted on a first rotating body 50a while being coupled to a plurality of vibrating elements 511. The second horn 52b is mounted on the second rotating body 50b in a state coupled to a plurality of vibrating elements 521. A plurality of transformers 111 are mounted on a first rotating body 50a and supply driving voltages to the vibrating elements 511. Similarly, a plurality of transformers 112 are mounted on a second rotating body 50b and supply driving voltages to the vibrating elements 521. |
