Document Type and Number:
WIPO Patent Application WO/2010/131381
Kind Code:
A1
Abstract:
Provided is an oscillation coupler wherein a supporting body can be attached to an object by engaging a mounting bolt in a large-diameter threaded hole provided in the object without changing the sizes of a shackle and the supporting body. An oscillation supporting mechanism wherein a shackle (5) is swingably supported by a supporting body (19) is provided. A mounting bolt (11) of the supporting body (19) is composed of a double-ended bolt wherein a first external thread portion (1) and a second external thread portion (2), which have different diameters, are separately formed on the opposed ends thereof. A bolt shaft (3), the diameter of which continuously varies, is formed between the first external thread portion (1) and the second external thread portion (2). A bolt hole (10) in which the bolt shaft (3) is fitted and locked, and through which the small-diameter second external thread portion penetrates is provided in the supporting body (19). The bolt hole (10) is shaped so that the inner diameter thereof continuously varies, and the inner surface thereof corresponds to the outer peripheral surface of the bolt shaft (3). A nut (6) is screw-engaged with the second external thread portion (2) which penetrates through the bolt hole (10), so that the mounting bolt (11) is prevented from being detached from the supporting body (19), and is integrally coupled to the supporting body (19).
