しめられる。 In the case of known devices of this type, the play between the slide guard and the sleeve is reduced so that:
The movement of the ram, which is adjusted according to the load of the car, can only be transmitted to the reflector inaccurately. In order to avoid this, if the play of the slide guide is increased, a delay is caused in particular when converting a rotational movement into a reciprocating movement when adjusting the basic position of the headlamp.

い。Effects of the Invention The advantage of the irradiation distance adjustable headlamp of the present invention is that the screw transmission is a spring fixed on one side by a ball to the push rod belonging to the operating part and on the other side to the reflector by a nut. Due to the spherical bearing on the curved piece, the required play can be kept to a minimum. Therefore, the transition from rotational motion to reciprocating motion is smoothly performed. Furthermore, since there is no slider guide, there is no frictional force that would interfere with the function.
