<P>PROBLEM TO BE SOLVED: To provide a light distribution device of vehicular headlamp in which a solenoid 6 is downsized, transmission performance and response for transmitting reciprocating displacement of a plunger shaft 7 to a movable shade are rapid, and positional accuracy of the plunger shaft 7 is improved. <P>SOLUTION: Since one end 8A of a coupling shaft 8 is fixed to a top end surface 7a of a plunger shaft 7 in pulling-out stop condition, a play (looseness) and friction are not caused between the plunger shaft 7 and the coupling shaft 8 at the time of energizing and non-energizing to a solenoid 6. Thereby, it is not necessary to enlarge a stroke of the plunger shaft 7, and downsizing of the solenoid 6 becomes possible. Further, the rigidity of the coupling shaft 8 of belt shape is large to make it hardly bent, and the transmission performance and response for transmitting the reciprocating displacement of the plunger shaft 7 to the movable shade are rapid. <P>COPYRIGHT: (C)2013,JPO&INPIT |
