Title:
ROTATION ADJUSTMENT MECHANISM AND HEADLIGHT DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/199262
Kind Code:
A1
Abstract:
This rotation adjustment mechanism comprises: a rotation module (101) supported so as to be freely rotatable about a first rotary shaft (15); and an adjustment unit (301) which includes a slider (32) that is movable along a slide shaft (34) which faces a direction perpendicular to the first rotary shaft. The adjustment unit (301) is supported so as to be freely rotatable about a second rotary shaft (35), and the rotation module (101) has a coupling groove (14a). The slider includes: a protrusion (33) that fits with the coupling groove; and slide members (32b, 32c). A fixing member has cam grooves (25a, 25b) which engage with the slide members and define the rotation of the adjustment unit about the second rotary shaft by using translational positions in two directions (Y, Z) which are perpendicular to the second rotary shaft and which are orthogonal to each other. With respect to a unit movement amount in a direction parallel to the slide shaft of the slider, the groove shape of the cam grooves is a circular arc shape which holds a fixed rotation angle about the first rotary shaft of a contact that is contacted by the coupling groove and the protrusion.
