In this embodiment, a fastening member such as a bolt is used as the connecting member 300. The fastening member has a shaft portion 310 that can be inserted into the first insertion hole 124h, the second insertion hole 134h, and the insertion hole 220h. The length of the insertion hole 220h in the radial direction is larger than the outer diameter of the shaft portion 310.

The cushioning member 400 is a member that alleviates the impact on the optical device 1 and the vibration of the optical device 1 with respect to the first support portion 122, the second support portion 132, and the auxiliary support portion 210. The cushioning member 400 is arranged on the inner peripheral surface of the first support portion 122, the inner peripheral surface of the second support portion 132, and the inner peripheral surface of the auxiliary support portion 210. That is, the buffer member 400 is provided between the inner peripheral surface of the first support portion 122 and the outer peripheral surface S of the optical device 1, between the inner peripheral surface of the second support portion 132 and the outer peripheral surface S of the optical device 1. , It is interposed between the inner peripheral surface of the auxiliary support portion 210 and the outer peripheral surface S of the optical device 1. The cushioning member 400 is made of, for example, rubber. The cushioning member 400 is formed in a sheet shape. The cushioning member 400 may be omitted.
　次に、固定具１０によって光学機器１を取付面２に対して垂直姿勢で固定する工程について説明する。 Next, a process of fixing the optical device 1 in a vertical posture with respect to the mounting surface 2 by the fixture 10 will be described.
　この工程は、光透過面Ｓａの中央部と中心軸Ａとを結ぶ直線Ｌ（図６を参照）がベース１１０と直交する姿勢となるように光学機器１が第１支持部１２２及び第２支持部１３２上に載置された状態において、図３及び図６に示されるように、接続部材３００によって第１フランジ１２４に補助フランジ２２０が接続される第１工程と、ベース１１０が取付面２にボルト等の締結部材によって固定される第２工程と、を含む。なお、第１工程と第２工程とは、この順に行われても良いし、逆の順に行われてもよいし、同時に行われてもよい。光学機器１が垂直姿勢で固定された状態では、図１及び図６に示されるように、光透過面Ｓａを透過する光が固定具１０によって遮られることが回避される。 In this step, the optical instrument 1 supports the first support portion 122 and the second support portion 122 so that the straight line L (see FIG. 6) connecting the central portion of the light transmitting surface Sa and the central axis A is in an attitude orthogonal to the base 110. As shown in FIGS. 3 and 6, the first step of connecting the auxiliary flange 220 to the first flange 124 by the connecting member 300 and the base 110 on the mounting surface 2 while mounted on the portion 132. It includes a second step of being fixed by a fastening member such as a bolt. The first step and the second step may be performed in this order, in the reverse order, or at the same time. When the optical device 1 is fixed in the vertical posture, as shown in FIGS. 1 and 6, it is avoided that the light transmitted through the light transmitting surface Sa is blocked by the fixture 10.
　続いて、固定具１０によって光学機器１を取付面２に対して水平姿勢で固定する工程について説明する。 Subsequently, a step of fixing the optical device 1 with the fixture 10 in a horizontal posture with respect to the mounting surface 2 will be described.
　この工程は、光透過面Ｓａの中央部と中心軸Ａとを結ぶ直線がベース１１０と平行となる姿勢となるように光学機器１が第１支持部１２２及び第２支持部１３２上に載置された状態において、図５及び図７に示されるように、接続部材３００によって第２フランジ１３４に補助フランジ２２０が接続される第３工程と、ベース１１０が取付面２にボルト等の締結部材によって固定される第４工程と、を含む。なお、第３工程と第４工程とは、この順に行われても良いし、逆の順に行われてもよいし、同時に行われてもよい。光学機器１が水平姿勢で固定された状態では、図２及び図７に示されるように、光透過面Ｓａを透過する光が固定具１０によって遮られることが回避される。 In this step, the optical instrument 1 is placed on the first support portion 122 and the second support portion 132 so that the straight line connecting the central portion of the light transmitting surface Sa and the central axis A is in a posture parallel to the base 110. In this state, as shown in FIGS. 5 and 7, the third step in which the auxiliary flange 220 is connected to the second flange 134 by the connecting member 300, and the base 110 is attached to the mounting surface 2 by a fastening member such as a bolt. Includes a fourth step of being fixed. The third step and the fourth step may be performed in this order, in the reverse order, or at the same time. When the optical device 1 is fixed in the horizontal posture, as shown in FIGS. 2 and 7, it is avoided that the light transmitted through the light transmitting surface Sa is blocked by the fixture 10.
　以上に説明したように、本実施形態の固定具１０では、補助固定部材２００の補助フランジ２２０は、接続部材３００によって第１フランジ１２４及び第２フランジ１３４のいずれにも接続可能である。このため、例えば、第１フランジ１２４に補助フランジ２２０が接続されることにより、光透過面Ｓａを透過する光が取付面２に対して直交する姿勢において、光透過面Ｓａを透過する光を遮ることなく光学機器１を取付面２に固定することが可能となる。同様に、第２フランジ１３４に補助フランジ２２０が接続されることにより、光透過面Ｓａを透過する光が取付面２と平行となる姿勢において、光透過面Ｓａを透過する光を遮ることなく光学機器１を取付面２に固定することが可能となる。 As described above, in the fixture 10 of the present embodiment, the auxiliary flange 220 of the auxiliary fixing member 200 can be connected to either the first flange 124 or the second flange 134 by the connecting member 300. Therefore, for example, by connecting the auxiliary flange 220 to the first flange 124, the light transmitted through the light transmitting surface Sa is blocked in a posture in which the light transmitted through the light transmitting surface Sa is orthogonal to the mounting surface 2. The optical device 1 can be fixed to the mounting surface 2 without any problem. Similarly, by connecting the auxiliary flange 220 to the second flange 134, the light transmitted through the light transmitting surface Sa is optical in a posture parallel to the mounting surface 2 without blocking the light transmitted through the light transmitting surface Sa. The device 1 can be fixed to the mounting surface 2.
　また、前記径方向における挿通孔２２０ｈの長さは、軸部３１０の外径よりも大きいため、第１フランジ１２４又は第２フランジ１３４に対する前記径方向における補助フランジ２２０の接続位置を調整することが可能となる。このため、補助支持部２１０による光学機器１の押付け力の調整が可能となる。 Further, since the length of the insertion hole 220h in the radial direction is larger than the outer diameter of the shaft portion 310, the connection position of the auxiliary flange 220 in the radial direction with respect to the first flange 124 or the second flange 134 can be adjusted. It will be possible. Therefore, the pressing force of the optical device 1 can be adjusted by the auxiliary support portion 210.
　また、固定具１０は、緩衝部材４００を備えているため、光学機器１の外周面Ｓの損傷が抑制される。 Further, since the fixture 10 includes the cushioning member 400, damage to the outer peripheral surface S of the optical device 1 is suppressed.
　（第２実施形態）
　次に、図１０及び図１１を参照しながら、本発明の第２実施形態の固定具１０について説明する。なお、第２実施形態では、第１実施形態と異なる部分についてのみ説明を行い、第１実施形態と同じ構造、作用及び効果の説明は繰り返さない。 (Second Embodiment)

Each flat surface portion 132a is orthogonal to the radial direction of the optical device 1. Of the three flat surface portions 132a, the cushioning member 400 is attached to the flat surface portions 132a at both ends in the longitudinal direction.

Each flat surface portion 210a is orthogonal to the radial direction of the optical device 1. The cushioning member 400 is attached to the flat surface portion 210a arranged on the side farther from the auxiliary flange 220 of the two flat surface portions 210a.
　緩衝部材４００は、各平面部を貫通した状態で当該平面部に取り付けられている。緩衝部材４００は、円筒状ないし円柱状に形成されている。 The cushioning member 400 is attached to the flat surface portion in a state of penetrating each flat surface portion. The cushioning member 400 is formed in a cylindrical shape or a columnar shape.
　なお、今回開示された実施形態はすべての点で例示であって、制限的なものではないと考えられるべきである。本発明の範囲は、上記した実施形態の説明ではなく請求の範囲によって示され、さらに請求の範囲と均等の意味および範囲内でのすべての変更が含まれる。 It should be noted that the embodiments disclosed this time are examples in all respects and should not be considered to be restrictive. The scope of the present invention is shown by the scope of claims rather than the description of the above-described embodiment, and further includes all modifications within the meaning and scope equivalent to the scope of claims.
　例えば、前記平面Ｐと前記直線Ｌとのなす角は、５５度とは異なる角度に設定されてもよい。 For example, the angle formed by the plane P and the straight line L may be set to an angle different from 55 degrees.
　また、前記沿い方向における第１支持部１２２の長さ、前記沿い方向における第２支持部１３２の長さ及び前記沿い方向における補助支持部２１０の長さは、各長さの和が光学機器１の外周面Ｓのうち光透過面Ｓａ以外の部位の光学機器１の周方向における長さ以下となる範囲で任意に設定されることが可能である。例えば、前記沿い方向における第１支持部１２２の長さと前記沿い方向における補助支持部２１０の長さとの和は、前記沿い方向における第２支持部１３２の長さと異なっていてもよい。 Further, the length of the first support portion 122 in the along direction, the length of the second support portion 132 in the along direction, and the length of the auxiliary support portion 210 in the along direction are the sum of the respective lengths of the optical instrument 1.
