JOINT UNIT
Document Type and Number:
WIPO Patent Application WO/2010/027056
Kind Code:
A1
Abstract:
A joint unit comprises a lock mechanism (L) in which a ball-like joint section (14) on the base end side of an arm (13) is stored in a holder (12) formed at the end of a cylindrical case (10) and the joint section (14) is pressed against the inner surface (12S) of the holder so as to fix the rotating angle.  In the lock mechanism (L), a bolt (18) is allowed to project into the case (10) by manually operating a knob (19), and the pressing force of the bolt is transmitted to a roller-like first pressing body (21) and a second pressing body (22) brought into contact with the first pressing body.  Also, the pressing force of the first pressing body (21) is transmitted to a pressure block (16), and the joint section (14) is pressed against the inner surface (12S) of the holder by the pressing force of the pressure block (16).
