<p>PURPOSE:To provide an illuminating axis tilting device for a head light, which can make a support structure simple, for an output gear moving to the axial direction, a driving shaft tilting the tilting members such as a reflecting mirror, a head light unit and the like, and which can also minimize non-conformity due to errors in dimension. CONSTITUTION:An output gear 45 is supported by a drive shaft 41 which is positioned penetrating a case 24 back and forth, a front and a rear case body 25a and 25b each of which is one-half of the case 24, are formed with cylindrical support walls 37 and 39 which are positioned in such a way as to enclose a part of each drive shaft, and each tip end 37a and 39a of the support walls is positioned so that the disc section 47 of the output gear is held back and forth while being slightly brought into contact with or being closely adjacent to the disc section. This thereby can make the support structure of the output gear simple, and also can minimize non-conformity due to errors in dimension.</p> |
