PROBLEM TO BE SOLVED: To provide a fixation device and an optical device, capable of suitably executing screwing with a bolt and a nut even in a case where there is no space for inserting a tool or the like.SOLUTION: A range finder 100 includes a spherical pedestal part 43 and a light source support part 44, which are objects to be fixed, and a bolt 70, a washer 71 and a nut 72, which are fixing members. The light source support part 44 has a first concave part 69 opposite to a convex surface part of the washer 71 adjacent to a head part of the bolt 70, and a screw hole 68 formed on the first concave part 69. The spherical pedestal part 43 has a second concave part 67 opposite to a convex surface part of the nut 72, and a screw hole 66 formed on the second concave part 67. The nut 72 has projection parts 73A, 73B interfering with rotation. The second concave part 67 has grooves 65A, 65B loosely fitting the projection parts 73A, 73B.SELECTED DRAWING: Figure 6 【課題】工具等を差し込むスペースがない場合であっても、ボルト及びナットを用いたねじ止めを好適に実行することが可能な固定装置及び光学装置を提供する。【解決手段】測距装置１００は、固定対象物である球面台座部４３及び光源支持部４４と、固定部材であるボルト７０、ワッシャー７１及びナット７２とを備える。光源支持部４４は、ボルト７０の頭部と隣接するワッシャー７１の凸曲面部と対向する第１凹部６９と、第１凹部６９に形成されたねじ穴６８とを有する。球面台座部４３は、ナット７２の凸曲面部と対向する第２凹部６７と、第２凹部６７に形成されたねじ穴６６とを有する。ナット７２は、回転を妨げる突出部７３Ａ、７３Ｂを有し、第２凹部６７は、突出部７３Ａ、７３Ｂを遊嵌する溝部６５Ａ、６５Ｂを有する。【選択図】図６
