The inner diameter D4 and the inner diameter D5 of the through hole 35 formed in the height adjusting member 31 are both sufficiently larger than the outer diameter D1 of the fixed shaft 40, and the maximum diameter portion 25a of the through hole 25 of the rotation operation member 21. The inner diameter D6 of the fixed shaft 40 is larger than the outer diameter of the flange portion 43 of the fixed shaft 40. Further, the inner diameter of the regulation hole 57 formed in the fixed substrate 56 is sufficiently larger than the outer diameter of the rotation stop protrusion 34 provided on the height adjusting member 31.

Therefore, under a slack state in which the fixed shaft 40 is not completely tightened, all the members of the first support member 15, the second support member 16, the movable adjustment member 11, the rotation operation member 21, and the height adjustment member 31 are attached to each other. It is possible to combine them without separating them and adjust them to move along a plane orthogonal to the fixed axis 40, that is, an XY plane. FIG. 9 shows an adjustment state in which all the members of the first support member 15, the second support member 16, the movable adjustment member 11, the rotation operation member 21, and the height adjustment member 31 are moved in the X1 direction. There is.
By this movement adjustment, the fixed position of the housing 51 of the head-up display 50 can be adjusted in the direction along the XY plane.

(Height adjustment)
Under a slack state in which the fixed shaft 40 is not completely tightened, a jig is fitted into the operation groove 26 of the rotation operation member 21 provided at the uppermost portion and rotated about the Z axis (center line O2). The first support member 15 connected to each other by the lower connecting portion 24 and the upper connecting portion 22 rotates together with the rotation operating member 21. As a result, the contact state between the lower adjustment step 32 formed on the height adjusting member 31 and the upper adjusting step 33 formed on the first support member 15 is switched. Since the rotation stop protrusion 34 provided on the height adjusting member 31 is located inside the regulating hole 57, the rotation of the height adjusting member 31 is restricted when the rotation operating member 21 is rotated. It is possible to rotate the first support member 15 in this state.

As shown in FIG. 7, the step portion 32b, which is the boundary between the adjacent staircase surfaces 32a in the lower adjustment step 32, is tilted counterclockwise at an angle α1 when viewed from above, and the upper adjustment step 33 is also adjacent to each other. The stepped portion 33b, which is the boundary of the staircase surface 33a, is tilted counterclockwise at an angle α2. Therefore, when the rotation operating member 21 is rotated counterclockwise when viewed from above with the fixed shaft 40 loosened, the contact state between the staircase surface 32a and the staircase surface 33a is smoothly switched. The height adjusting member 31 and the first support member 15 are adjusted in a direction away from each other along the center line O1.

On the contrary, when the first support member 15 is rotated clockwise when viewed from above together with the rotation operation member 21, the height adjusting member 31 and the first support member 15 approach each other along the center line O1. Adjusted to.

In the device fixing device 10, the relative rotation angle between the first support member 15 and the height adjusting member 31 can be changed by operating the rotation operation member 21 located at the uppermost portion to rotate the device 21 from above. Therefore, the height adjustment work is easy.

By this height adjustment work, it becomes possible to adjust the height position of the fixing bracket 51a provided in the housing 51 shown in FIG. 3 in the Z1-Z2 direction.

(Fixing work)
After performing the tilt adjustment, the movement adjustment, and the height adjustment in combination, the jig is fitted to the operation head 42 of the fixed shaft 40 and tightened to the female screw hole 58 of the fixed substrate 56, so that the fixed shaft 40 is provided. The second support member 16, the movable adjustment member 11, the first support member 15, and the height adjustment member 31 are pressed against the fixed substrate 56 by the flange portion 43, and the respective members are fixed so as not to move with each other. Will be done.

Since the position of the housing 51 can be adjusted in multiple directions by the adjustment work, the virtual image 63 shown in FIGS. 1 and 2 can be adjusted so as to be within the visual field of the eye 62 of the viewer 61. .. Further, even if the magnification of the projection lens 53 and the reflection member 55 is increased to increase the angle of view of the virtual image 63, the virtual image 63 can be adjusted to be within the field of view.

The device of the present invention is not limited to the head-up display, and may be another precision optical device or electronic device. By using the device fixing device 10, it is possible to perform positioning adjustment of these various devices with high accuracy.
