Further, a leg 27 is attached to the lower portion of the base body 2, and a protective member 28 for protecting, for example, a floor surface on which the leg 27 is placed is attached to the leg 27.

A lid 31 is mounted on the front side of the frame 11 so as to be openable and closable. The lid 31 has an annular portion 32 having substantially the same diameter as the frame 11, and an annular flange portion 33 is formed on the front side of the annular portion 32 so as to project inward, and the front surface of the flange portion 33 is formed. A glass locking projection 35 that locks the front glass 34 in a state of being flush toward the inside from the position is further inwardly projected, and is opened at the tip peripheral edge of the glass locking projection 35. The part 36 is formed.

Further, a shaft insertion hole 37 corresponding to the shaft insertion hole of the frame body 11 is formed in the lower portion of the lid body 31, and the shaft insertion hole of the lid body 31 is formed.
The shaft 38 is inserted into the shaft insertion holes of 37 and the frame body 11, and the lid body 31 is configured to be openable and closable with respect to the frame body 11.

Further, FIG. 6 is a cross-sectional view showing the lid body. As shown in FIGS. 1, 2 and 6, inside the lid body 31, a front glass 34 for reducing glare of the halogen lamp 4 and the like are protected. A glare cap 40 is attached, and in this glare cap 40, a semi-spherical cap portion 41 having a hollow inside is attached at a position facing the halogen lamp 4 in a state where the lid body 31 is closed. The tip of the lamp 4 is located. That is, a plate body 42 of a leaf spring is attached to the cap portion 41 along the radial direction in the direction in which the flat surface presses the front glass 34.
The upper side of the is a fixed leg 43 for fixing the cap part 41, and the lower side of the cap part 41 is a pressing leg 44 for pressing and holding the front glass 34.

A mounting plate portion 46 having a mounting hole 45 is formed at the tip of the fixed leg 43, and the tip of the pressing leg 44 is divided into two to form a U-shaped pressing portion 47 for pressing and holding the front glass 34. Has been done.

Further, 51 is a locking body, and the base end of this locking body 51 is bent at a substantially right angle to form a mounting portion 52, and this mounting portion 52 is fixed by a screw 53 to the fixing leg 43 of the glare cap 40. It is also fixed to the lid 31. A locking portion 54 that is locked to the locking portion 15 of the frame body 11 and a taper portion 55 that serves as a hooking piece when removed is formed by bending at the tip of the locking body 51. ing.

Next, the usage state of the above embodiment will be described.

First, in a normal state, with the halogen lamp 4 mounted in the lamp socket 3, the lid 31 is rotated around the shaft support 12 to superimpose the lid 31 on the frame 11 and the locking body 51.
Is locked to the locking portion 15 of the frame body 11, and the irradiation opening 8 is closed by the lid body 31 with the cap portion 41 of the glare cap 40 facing the tip of the halogen lamp 4.

When the halogen lamp 4 is replaced, the tapered portion 55 of the locking body 51 is pressed to the center of the frame body 11, and the locking portion 54 of the locking body 51 is projected onto the projection 13 of the frame body 11. Then, the lid body 31 is rotated about the shaft support portion 12 to open the lid body 31, and by opening the lid body 31, the cap portion 41 of the glare cap 40 attached to the lid body 31 is released. The halogen lamp 4 is no longer facing the halogen lamp 4, and the halogen lamp 4 is removed from the lamp socket 3.

Then, the halogen lamp 4 is attached to the lamp socket 3 again, the lid 31 is rotated around the shaft support 12, and the tapered portion 55 of the tip of the locking body 51 is brought into contact with the projection 13 of the frame 11. When the tip end side of the locking body 51 moves along the tapered portion 55 and the locking portion 54 of the locking body 51 crosses the protrusion 13 of the frame body 11,
The locking portion 54 of the locking body 51 is locked to the protrusion 13 of the frame body 11,
31 is locked to the frame 11.

Further, the front glass 34 is replaced to replace the front glass.
When changing the color of 34 or the like, similarly, the lid body 31 is rotated and released from the frame body 11, and the pressing leg 44 of the glare cap 40 is lifted as shown by the two-dot chain line in FIG. Lift 47 from front glass 34 and slide front glass 34 for replacement. Then, after the front glass 34 is replaced, the pressing leg 44 of the glare cap 40 is lifted again to press the front glass 34 and fix the front glass 34.

According to the above-described embodiment, the irradiation light from the halogen lamp 4 cannot be effectively used as compared with the conventional one having the flat portion of the plate 42 in the direction orthogonal to the front glass, The springiness of the plate body 42 can be utilized to elastically and reliably press the front glass 34.

Further, since the projecting plate 16 attached to the shaft body 18 is positioned in front of the base body 2, the weight in front of the projecting plate 16 can be relatively lightened even if the lid 31 side is heavy. Since the rear weight can be made relatively heavy, the front side of the instrument body 1 can be prevented from sinking. Further, since the spring washer 25 and the flat washer 26 are inserted in the adjusting screw 21, the instrument body 1 can be held more reliably.
