【００２６】
この発明の第２の実施の形態を図５に示す。第１の実施の形態との違いは、器具本体１に設けた取付台８側に長孔１４を設け、この長孔１４を貫通する固定具１３で、取付部４と反射板３の間に弾性体１２を介在させて、固定具１３の締め付けと弾性体１２の弾力で反射板３に常時テンションをかけておくことにより反射板３が長孔範囲内で可動状態になるように器具本体１に取り付けた構成をとっている。この場合、第１の実施の形態と比較して取付板１１が不要となり反射板３のみの構成をとっている。
【００２７】
この発明の第３の実施の形態を図６に示す。第１の実施の形態との違いは、反射板３の取付板１１側に長孔１４を設け、この長孔１４を貫通する固定具１３で、固定具１３の頭部と取付板１１の間に平板状の弾性体１２ａを介在させて、固定具１３の締め付けと弾性体１２ａの弾力で取付板１１に常時テンションをかけておくことにより反射板３が長孔範囲内で可動状態になるように器具本体１に取り付けた構成をとっている。
