Document Type and Number:
WIPO Patent Application WO/2017/057759
Kind Code:
A1
Abstract:
[Problem] To provide a compact angle adjustment tool which allows a desired angle change, is easy to use, and is less likely to rattle. [Solution] This angle adjustment tool reciprocally moves a lock body along one axial center to restrict and release axial rotation of a first member and second member. When the lock body is moved forward, axial rotation of the first member and the second member is restricted by engaging an axial uneven article provided on a frustoconical part of the lock body and an uneven part which is provided on a hole part of a first member capable of receiving the frustoconical part and can be engaged with the uneven article of the frustoconical part. When the lock member is moved backward, the restriction of axial rotation of the first member and the second member can be released by separating the uneven article of the frustoconical part and the uneven part provided on the hole part of the first member.
