PCT No. PCT/JP92/01525 Sec. 371 Date Apr. 30, 1993 Sec. 102(e) Date Apr. 30, 1993 PCT Filed Nov. 20, 1992.A device for confirming the optical-axis adjustment of an automotive headlamp in which the initial-setting mechanism for the level is composed of a reduced number of parts, the level can be simply attached and the initial setting of the revel can be simply adjusted. The casing of the level and the resilient member are formed integrally with each other, so that the initial setting mechanism for the level can be composed of a reduced number of parts. The level has an engagement projection formed thereon and the to-be-adjusted body has provided thereon a receptacle having an engagement hole. The level can be installed in the receptacle simply and securely by driving the initial-setting adjusting screw into the engagement projection. A seat portion is provided around the head of the initial-setting adjusting screw. The seat portion has provided thereon a mount surface formed nearly perpendicular to the axis of the initial-setting adjusting screw and on which a tool is mounted. So, when adjusting the initial setting of the level by turning the initial-setting adjusting screw by means of the tool, the level will not be moved against the resilience of the resilient member and the state of the level will not be deviated from the initial one. Thus, the initial setting of the level can be simply adjusted.
