PURPOSE:To prevent the damage of a light (small lamp) even if an excessive force is applied thereto by improving the structure for installing the light (small lamp) through a sphere joint formed by a combined assembly consisting of a concave spherical surface seat and a convex spherical member. CONSTITUTION:A convex spherical member 5c is not fixed directly to a light (small lamp 2) but engagingly attached thereto through an arc shape leg 5b and a hook 5a. When this part receives any excessive force in a compression direction, the arc shape leg 5b is deformed and when it receives any excessive force in a tensile direction, the hook 5a is separated so that the damage of the light (small lamp 2) can be prevented due to absorption of those excessive forces by such deformation and separation. |
