PROBLEM TO BE SOLVED: To provide a reflection plate attaching device capable of easily attaching or detaching a reflection plate from a support bracket.SOLUTION: A reflection plate attaching device 20 includes an attaching part 30 for attaching a cylindrical support bracket, and an attached part 40 to which the reflection plate is attached. The attaching part 30 includes an arc-like part 31 for holding the support bracket, and a pair of expansion parts 32 which are arranged at both ends of the arc-like part 31 and expand by elasticity of the arc-like part 31. The arc-like part 31 deforms in such a manner as in natural state, a gap R2 at the tip end of the pair of expansion parts 32 is smaller than a diameter R1 of the support bracket, while, under such condition as a force is applied, a gap R2 at the tip end of the pair of expansion parts 32 becomes larger than a diameter R1 of the support bracket. The attached part 40 includes a bending part 41 which bends at one end part of the pair of expansion parts 32, and an extension part 42 which extends from the end part of the bending part 41 so as to approach the arc-like part 31. The bending part 41 has elasticity such that the extension part 42 comes away from the arc-like part 31.COPYRIGHT: (C)2014,JPO&INPIT【課題】支持具に反射板を容易に取り付けることができるとともに、取り外すことができる反射板取付装置を提供する。【解決手段】反射板取付装置20は、円筒状の支持具に取り付ける取付部30と、反射板が取り付けられる被取付部40とを備え、取付部30は、支持具を保持する弧状部31と、弧状部31の両端に配置され、弧状部31の弾性によって拡がる一対の拡開部32とを備え、自然状態では、一対の拡開部32の先端の間隙R2が支持具の直径R1よりも小さい一方、力が加えられた状態では、一対の拡開部32の先端の間隙R2が支持具の直径R1よりも大きくなるように弧状部31が変形する。被取付部40は、一対の拡開部32の一方の端部から折れ曲がる折曲部41と、折曲部41の端部から弧状部31に近接するように延びる延出部42とを備え、延出部42が弧状部31に対して離隔するように折曲部41が弾性を有する。【選択図】図4
