Title:

FLOATING JOINT AND ULTRASONIC OSCILLATION JOINING DEVICE

Document Type and Number:

WIPO Patent Application WO/2021/210083

Kind Code:

A1

Abstract:

The purpose of the present disclosure is to provide a floating joint having a structure in which a contact-released state does not arise between first and second connection parts during use. This floating joint (10) has a drive-side linking part (20) formed from first and second connection parts, and a driven-side linking part (30). A pressure adjustment structure (40) of the floating joint (10) has elasticity and is provided without any gap between a bottom surface exposure region (22r) of a contact sphere part (22) and a bottom surface facing region (42r) of a fixed ring (42). Therefore, in the floating joint (10), the apex region of the contact sphere part (22) comparatively firmly maintains a one-side sphere contact relationship with one section of a bottom surface part (31a) of a frame body (31) due to the elastic force of the pressure adjustment structure (40).
