PROBLEM TO BE SOLVED: To provide a dental mirror which facilitates the attachment and detachment of a mirror part by this invention.SOLUTION: A dental mirror 2 disclosed in this invention comprises a mirror support body 4 and a mirror part 3. The mirror support body 4 includes a connection rod 43 having connection means that is attachable to and detachable from a holding handle 5 and a mirror part setting plate 41 which is a plain surface continuously connected to the connection rod 43 and has an insertion hole 42 of a polygon that penetrates in a perpendicular direction to the plain surface. The mirror part 3 includes a mirror insertion dish 32 where a mirror 31 is fitted, a rotation auxiliary column 33 which has the same height as a thickness of the insertion hole 42 and allows the mirror part 3 and the mirror support body 4 to rotate relatively on a surface on the opposite side of the mirror insertion dish 32, and a fixing plate 34 which has the substantially identical polygonal shape with the shape of the insertion hole 42 when being seen in a perpendicular direction to the mirror 31 and is provided on a bottom surface side opposing to a mirror surface side of the rotation auxiliary column 33. The mirror part 3 and the mirror support body 4 are relatively rotated to be fixed.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】本発明により、鏡部の着脱を容易に行うことができるデンタルミラーを提供することを目的とする。【解決手段】この発明は、ミラー支持体4と鏡部3とを備えるデンタルミラー2であって、ミラー支持体4を、保持用取手5に着脱可能な接合手段を有する接続杆43と、接続杆43と連接する平面であるとともに、平面に対して垂直方向に貫通する正多角形の挿入孔42を有した鏡部設置板41とを備え、鏡部3を、ミラー31を嵌め込んだ鏡挿着皿32と、鏡挿着皿32の反対側の面に挿入孔42の厚さと略同一の高さであるとともに、鏡部3とミラー支持体4とを相対的に回転可能となるようにした回転補助円柱33と、ミラー31に対して垂直方向から視て挿入孔42と略同一の正多角形を呈するとともに、回転補助円柱33の鏡面側に対向する底面側に設けられた固定板34とを備え、鏡部3とミラー支持体4とを相対的に回転して固定可能となるようにした。【選択図】図2
