Ultrasonic vibration generation and transmission unit connection mechanism and method of manufacturing ultrasonic vibration generation and transmission unit
The connection mechanism (300) of the ultrasonic vibration generation / transmission unit (200) is disposed in each part forming the ultrasonic vibration generation / transmission unit (200) for generating and transmitting ultrasonic vibration. The parts are connected together to form (200). One end (41a) is inserted into the cylinder member (301) from the one end (341a) on the cylinder side, and the other end (51a) is connected to the other connection (51g) with the cylinder side connection (351g). When inserted into the cylindrical member (301) from the other end portion (351a) on the cylinder side, the clamped portion (41c) and the end surface (511a) of the other end portion (51a) in the axial direction of the cylindrical member (301) By being sandwiched between the projecting portions (341c), the one end portion (41a) and the other end portion (51a) are connected to each other.超音波振動発生伝達ユニット（２００）の接続機構（３００）は、超音波振動を発生及び伝達する超音波振動発生伝達ユニット（２００）を形成する各パーツに配設され、超音波振動発生伝達ユニット（２００）を形成するために前記パーツ同士を互いに接続する。一方端部（４１ａ）が筒側一端部（３４１ａ）から筒部材（３０１）に挿入され、他方接続部（５１ｇ）が筒側接続部（３５１ｇ）と接続するように他方端部（５１ａ）が筒側他端部（３５１ａ）から筒部材（３０１）に挿入された際、筒部材（３０１）の軸方向において被挟持部（４１ｃ）が他方端部（５１ａ）の端面（５１１ａ）と筒側突出部（３４１ｃ）とによって挟持されることで、一方端部（４１ａ）と他方端部（５１ａ）とが互いに接続する。
