Abstract: A connecting method includes: measuring at least one of control dimensions that influence a dimension of a member obtained by connection of a first member and a second member to each other, the second member including a connection insertion portion where the first member is inserted; determining, according to the at least one of the control dimensions, a relative position for positioning the first member and the second member by insertion of the first member in the connection insertion portion; heating the second member to a first temperature; inserting the first member in the connection insertion portion to place the first member and the second member in the relative position; and stopping the heating of the second member and maintaining the first member and the second member in the relative position.

Abstract: A joining method of joining two pieces of subjects to be joined together, the subjects being a first member and a second member that has a joint insertion portion in which the first member is inserted, the method including: heating the second member that is set in an expansion restricting member and in which the first member is inserted to the joint insertion portion to first temperature to cause the second member to have thermal expansion and thereby causing the joint insertion portion to have plastic deformation in a direction in which a diameter shrinks with mechanically restricting thermal expansion of the second member by an inner surface of the expansion restricting member; and cooling the second member after the heating to join the first member and the second member together.

Abstract: A probe is connected to an ultrasonic transducer capable of generating ultrasonic vibration. The probe includes an elongated main body portion, and a cylindrical engagement portion. The main body portion is capable of transmitting the ultrasonic vibration. The ultrasonic vibration is input to the engagement portion. The engagement portion includes: a connection portion that is connected to the ultrasonic transducer, and a holding cylindrical portion that is continuous to the connection portion, and that holds the proximal end portion of the main body portion.

Abstract: A probe configured to be connected to a transducer unit configured to generate ultrasonic vibration, includes an elongated vibration transmission portion configured to transmit the ultrasonic vibration; and an engagement member provided on and/or near an outer circumference at a position which becomes a node of the ultrasonic vibration when the ultrasonic vibration is transmitted to the vibration transmission portion, the engagement member being formed by a material of an identical to or smaller damping rate than a damping rate of the ultrasonic vibration in the vibration transmission portion, and the engagement member being engaged with an exterior member disposed on an outer side of the vibration transmission portion.
