1. An ultrasonic transmitting unit comprising:
an ultrasonic vibrator which is configured to generate an ultrasonic vibration; a first vibrating section which is configured to transmit the ultrasonic vibration generated by the ultrasonic vibrator toward a first transmitting direction, and thereby configured to perform a vibration having an antinode position and a node position at a predetermined frequency; a second vibrating section which is configured to perform a vibration having an antinode position and a node position at the same predetermined frequency as in the first vibrating section when the ultrasonic vibration is transmitted from the first vibrating section; a relay portion which relays between the first vibrating section and the second vibrating section, and which is configured to transmit the ultrasonic vibration toward the first transmitting direction from the first vibrating section to the second vibrating section, the relay portion being positioned at a position corresponding to one of the antinode position of the vibration in the first vibrating section and different from the antinode position and the node position of the vibration in the second vibrating section in a state that the first vibrating section and the second vibrating section vibrate at the predetermined frequency; a non-contact vibrating portion which is provided in the second vibrating section, and which extends from the relay portion toward a second transmitting direction side in a state that the non-contact vibrating portion is not in contact with the first vibrating section, when an opposite direction with respect to the first transmitting direction is a second transmitting direction; and a treatment portion which is provided in the non-contact vibrating portion of the second vibrating section, and which is formed in a second-transmitting-direction-side end portion of the second vibrating section, the treatment portion being configured to treat a treatment object by use of the ultrasonic vibration. |
