It functions as an insertion portion 34 into which the portion 26 is inserted. Further, the notch 33 is provided with an attachment portion 35 for attaching the light-shielding hood 30 to the instrument main body 10 at the other end 33B in the circumferential direction. As described above, the notch 33 is provided with the insertion portion 34 into which the protrusion 26 is inserted and the attachment portion 35 for attaching the light-shielding hood 30 to the instrument main body 10 in succession.

取付部３５は、切欠部３３の上縁４０Ａから、遮光フード３０の径方向外側に延出する板状部材を断面Ｕ字形状折り曲げて形成されている。取付部３５の板幅Ｗ２は、少なくとも、取付部３５の内側に突出部２６を位置させて、固定することができように構成されている。取付部３５は、この断面Ｕ字形状の板状部材で、器具本体１０の突出部２６を出射面１１Ａ側およびその裏面１１Ｂ側から挟む形状に形成されている。 The mounting portion 35 is formed by bending a plate-shaped member extending radially outward of the light-shielding hood 30 from the upper edge 40A of the cutout portion 33 into a U-shaped cross section. The plate width W2 of the mounting portion 35 is configured so that at least the protruding portion 26 can be positioned and fixed inside the mounting portion 35. The mounting portion 35 is a plate-shaped member having a U-shaped cross section, and is formed so as to sandwich the protruding portion 26 of the instrument main body 10 from the exit surface 11A side and the back surface 11B side thereof.

図４に示すように、遮光フード３０を器具本体１０に取り付ける際には、器具本体１０の突出部２６が夫々、遮光フード３０の切欠部３３に挿入部３４から挿入されるように、遮光フード３０を器具本体１０の出射面１１Ａ側から被せる。そして、遮光フード３０を、切欠部３３の一方の端部３３Ａ側から他方の端部３３Ｂ側に突出部２６を案内するように、器具本体１０の外周に沿ってスライド（回転）させる。取付部３５は、突出部２６が切欠部３３の他方の端部３３Ｂの側縁４０Ｂに当接するまで遮光フード３０を器具本体１０に対して回転させることで、取付部３５のＵ字の内側に突出部２６が位置するように構成されている。遮光フード３０は、上述したように、取付部３５によって、器具本体１０の突出部２６を出射面１１Ａ側およびその裏面１１Ｂ側から挟むように構成されている。このため、突出部２６を取付部３５のＵ字の内側に位置させることで、遮光フード３０の光軸に沿った上下方向への動きが規制される。 As shown in FIG. 4, when the light-shielding hood 30 is attached to the instrument main body 10, the light-shielding hood is inserted so that the protruding portions 26 of the instrument main body 10 are inserted into the notch 33 of the light-shielding hood 30 from the insertion portion 34, respectively. 30 is covered from the exit surface 11A side of the instrument body 10. Then, the light-shielding hood 30 is slid (rotated) along the outer circumference of the instrument main body 10 so as to guide the protruding portion 26 from one end 33A side of the notch 33 to the other end 33B side. The mounting portion 35 is formed inside the U-shape of the mounting portion 35 by rotating the light-shielding hood 30 with respect to the instrument body 10 until the protruding portion 26 abuts on the side edge 40B of the other end portion 33B of the notch portion 33. The protrusion 26 is configured to be located. As described above, the light-shielding hood 30 is configured such that the protruding portion 26 of the instrument main body 10 is sandwiched from the exit surface 11A side and the back surface 11B side thereof by the mounting portion 35. Therefore, by locating the protruding portion 26 inside the U-shape of the mounting portion 35, the movement of the light-shielding hood 30 in the vertical direction along the optical axis is restricted.

取付部３５は、遮光フード３０と別体に形成され、遮光フード３０にスポット溶接等で固定されている構成であっても良い。また、取付部３５は、遮光フード３０に一体に形成された板状部を折り曲げて形成されている構成であっても良い。 The mounting portion 35 may be formed separately from the light-shielding hood 30 and may be fixed to the light-shielding hood 30 by spot welding or the like. Further, the mounting portion 35 may be formed by bending a plate-shaped portion integrally formed with the light-shielding hood 30.

また、取付部３５には、折り曲げ可能に形成された爪部３６が設けられている。爪部３６は、遮光フード３０を器具本体１０に被せ、突出部２６を取付部３５のＵ字の内側に位置させた後に特殊な工具などを使うことなく容易に折り曲げ可能に構成されている。爪部３６は、取付部３５のＵ字の内側に突出部２６が出入りする側の取付部３５の端縁に設けられている。
爪部３６は、取付部３５の内側に突出部２６が位置している状態で、遮光フード３０の内径方向に向かって折り曲げられる。これにより、突出部２６は、切欠部３３の他方の端部３３Ｂの側縁４０Ｂと、爪部３６との間に挟まれる。このように、器具本体１０の突出部２６を切欠部３３の側縁４０Ｂと、取付部３５の爪部３６との間に挟むことで、遮光フード３０のスライド方向（回転方向）への移動が規制される。 Further, the mounting portion 35 is provided with a claw portion 36 formed so as to be bendable. The claw portion 36 is configured to be easily bent without using a special tool or the like after the light-shielding hood 30 is put on the instrument main body 10 and the protruding portion 26 is positioned inside the U-shape of the mounting portion 35. The claw portion 36 is provided at the end edge of the mounting portion 35 on the side where the protruding portion 26 enters and exits inside the U-shape of the mounting portion 35.
The claw portion 36 is bent toward the inner diameter of the light-shielding hood 30 with the protruding portion 26 located inside the mounting portion 35. As a result, the protruding portion 26 is sandwiched between the side edge 40B of the other end portion 33B of the cutout portion 33 and the claw portion 36. In this way, by sandwiching the protruding portion 26 of the instrument body 10 between the side edge 40B of the notch 33 and the claw portion 36 of the mounting portion 35, the light-shielding hood 30 can be moved in the sliding direction (rotational direction).
