<P>PROBLEM TO BE SOLVED: To provide a connection structure between a cap and a support, which employs only a single type of cap, and is available for the case where a reflector is attached and the case where the reflector is not attached. <P>SOLUTION: The cap 3 is formed of a head 31, an insertion portion 33 inserted into an upper end of the support 1, and a circumferential groove 34, and a lower end external diameter of the head is set to a size equal to or in excess of an upper end external diameter of the support 1. The single type of cap is employed in the connection structure. When the reflector 4 is necessary, the insertion portion 33 of the cap 3 having the reflector 4 attached to the groove 34 is inserted into an inside surface of the support 1 until a lower edge 45 of the reflector abuts on an upper edge 11 of the support. On the other hand, if the reflector 4 is unnecessary, the insertion portion 33 of the cap 3 not having the reflector 4 attached thereto is inserted into the inside surface of the support 1 until a head lower edge 32 abuts on the upper edge 11 of the support. In the latter case, the groove portion 34 is invisible from outside, and therefore deterioration of the appearance of the support can be avoided. <P>COPYRIGHT: (C)2008,JPO&INPIT |
