Claims (1)

[Claims for Utility Model Registration] 1. In a vibratory expansion machine having an oscillating device attached with two rotary pendulums having eccentric masses with relative phase positions that enable diagonal directional vibrations, the motor is rotated by a power mechanism. One rotary pendulum and main gear are fixed to the main shaft to which the other rotating pendulum is fixed, and the driven gear to mesh with this main gear is loosely fitted to the driven shaft to which the other rotating pendulum is fixed. An ankle-shaped clutch arm is pivoted so that it can be swung by a clutch lever, and an engaging protrusion is provided on the surface of the driven gear so that either end of the clutch arm can be selectively engaged by the swiveling. On the other hand, a contact rod that is to be in cross-contact with the clutch lever is prepared, and this contact rod is fixed to a vibration expansion machine so that it can be swung by connecting an operating wire, and the contact rod has elasticity that allows it to cross over the clutch lever. A vibration direction switching device in a vibratory expansion machine, characterized in that the device is provided between the vibration direction and the pivot shaft. 2. The vibration direction switching device in a vibratory rolling machine according to claim 1, wherein the contact rod is fixed at a location other than the vibration excitation device in the vibrating rolling machine. 3. In the vibratory expansion machine according to claim 1 or 2 of the utility model registration claim, in which the engaging surfaces of both ends of the clutch arm and the engaging surface of the engaging protrusion are sloped so that they bite into each other when engaged. Vibration direction switching device. 4. A vibration direction switching device in a vibratory rolling machine according to claim 1, 2, or 3 of the utility model registration claim, in which the tip of the clutch lever is sword-shaped. 5. By inserting the contact rod into the horizontal hole drilled in the pivot base via a bush made of elastic resin,
Switching of vibration direction in a vibratory rolling machine according to claim 1 or 2 or 3 or 4, which is a means for providing elasticity between the contact rod and the pivot that allows the clutch lever to be overcome. Device.
