Title:
ROTATION ADJUSTMENT MECHANISM AND HEADLIGHT DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/199257
Kind Code:
A1
Abstract:
Provided is a rotation adjustment mechanism comprising: a module to be rotated (104) which is supported so as to be rotatable about a first rotation axis (15) with respect to a fixed member (204); and an adjustment unit (304) which is fixed to the fixed member (204) and comprises a slider (32) movable along a slide axis (34) oriented toward a direction perpendicular to the first rotation axis. The module to be rotated comprises a connection groove (16). The slider comprises a protruding portion (33) which fits to the connection groove. The rotation of the module to be rotated about the first rotation axis is restricted by a contact point at which the connection groove and the protruding portion are in contact with each other. A surface of the connection groove in contact with the protruding portion has a shape formed from a trajectory sequentially connecting the contact points between the connection groove and the protruding portion, each of the contact points being obtained each time the module to be rotated is moved about the first rotation axis by a unit angle and the protruding portion fixed to the slider is simultaneously translated by a certain amount in a direction parallel with the slide axis.
