Next, the 1 st position adjustment unit M1 will be described. The 1 st position adjustment portion M1 includes a cylindrical female screw 37 formed in the longitudinal intermediate portion of the top plate 31 of the main hinge member 30 and projecting toward the intermediate member 20, a housing hole 28 formed in the distal end portion of the top plate 21 of the intermediate member 20, and an adjustment screw 70.

The housing hole 28 extends in the front-rear direction D1 and has an open front end, is provided at both side edges of the housing hole 28 for the engagement portion 29, and as shown in fig. 11, a raised portion 29a is formed at the center of both surfaces of each engagement portion 29 in the front-rear direction D1, and the edge of the raised portion 29a is provided for a contact portion 29b to be described later.

As shown in fig. 5 and 6, the adjusting screw 70 is composed of a screw main body 71 and a washer 77. The screw main body 71 includes, in order from an outer end to an inner end thereof along an axis extending in the left-right direction D3, an external thread portion 72, a head portion 73 having a smaller diameter than the external thread portion 72, a washer mounting portion 74 having a smaller diameter than the head portion 73, and a caulking portion 75. A tool insertion groove 71a is formed on an outer end surface of the screw main body 71.

The washer 77 is mounted on the washer mounting portion 74. The washer 77 is sandwiched between the annular step between the head 73 and the washer mounting portion 74 and the caulking portion 75, and is supported so as not to be rotatable with respect to the screw main body 71.

In the present embodiment, the inner end portion 76 (end portion on the head 73 side) of the male screw portion 72 of the adjusting screw 70 is used as the 1 st clamping portion, and the washer 77 is used as the 2 nd clamping portion. These inner end portion 76 and washer 77 are of a larger diameter than head 73. As shown in fig. 11, the surfaces of the inner end portion 76 of the male screw portion 72 and the washer 77 facing each other are formed by annular flat surfaces orthogonal to the axis of the adjustment screw 70, and are used as

engagement surfaces

76a, 77 a.

The male screw portion 72 of the adjustment screw 70 is screwed into the female screw portion 37 of the main hinge member 30, and the inner end portion 76 thereof protrudes from the female screw portion 37 toward the intermediate member 20. The head 73 of the adjustment screw 70 passes through the receiving hole 28 of the intermediate member 20. The inner end portion 76 of the male screw portion 72 and the washer 77 sandwich the engagement portion 29 formed on both sides of the housing hole 28. The distance between the engaging

surfaces

76a, 77a is substantially equal to the distance between the abutting portions 29a on both surfaces of the engaging portion 29, and thus the engaging

surfaces

76a, 77a are substantially in contact with the abutting portions 29 b.

When the adjustment screw 70 is rotated, the adjustment screw 70 advances and retreats in the right and left direction D3 with respect to the main hinge member 30, since the engagement surfaces 76a and 77a of the adjustment screw 70 are engaged with the engagement portion 29 of the intermediate member 20, the main hinge member 30 rotates in the right and left direction D3 about the slide shaft 35 as the adjustment screw 70 advances and retreats, and thus the distal end portion of the main hinge member 30 is adjusted in position in the right and left direction D3, and further, fan 2 is adjusted in position in the right and left direction, and it is pointed out that the rotation range of the main hinge member 30 accompanying the right and left direction position adjustment is about 4 ° at the maximum.

The position adjustment mechanism M further includes a resin rotation suppressing member 80. as shown in FIGS. 12 to 16, the rotation suppressing member 80 has a plate shape elongated in the front-rear direction D1. the body includes a 1 st insertion portion 81 formed at a front end portion, a 2 nd insertion portion 82 formed at a rear end portion, a bridging portion 83 for connecting the 1 st insertion portion 81 and the 2 nd insertion portion 82, and a frictional engagement portion 85 connected to the intermediate member 20 side of the 1 st insertion portion 81.

The 1 st, 2 nd and frame

joint parts

81, 82 and 83 are located between the top plate part 21 of the intermediate member 20 and the top plate part 31 of the main hinge member 30, and abut against the side wall part 32 opposite to the of the main hinge member 30, whereby the rotation of the rotation suppressing member 80 with respect to the intermediate member 20 and the main hinge member 30 can be inhibited.

The 1 st accommodating portion 81 has an accommodating cavity 81a having a circular cross section, and both ends of the accommodating cavity 81a in the left-right direction D3 are open. As shown in fig. 5 and 6, the female screw portion 37 of the main hinge member 30 and the inner end portion 76 of the male screw portion 72 of the adjusting screw 70 protruding from the female screw portion 37 are housed in the housing cavity 81 a.

The frictional engagement portion 85 is a rectangle extending in the front-rear direction D1, and both surfaces thereof form flat surfaces perpendicular to the axis of the housing cavity 81a extending in the left-right direction D3. The frictional engagement portion 85 has a width substantially equal to that of the housing hole 28 of the intermediate member 20, and is inserted into the housing hole 28 to be displaceable in the front-rear direction D1. Accordingly, positional adjustment of the primary hinge member 30 relative to the intermediate member 20 in the fore-aft direction D1 is permitted. The frictional engagement portion 85 crosses the opening of the housing cavity 81a on the side of the intermediate member 20. Since the width of the frictional engagement portion 85 is smaller than the opening diameter of the housing cavity 81a, the exposure windows 86 are formed on both sides of the frictional engagement portion 83 in the vertical direction D2. In the exposure window 86, a surface of the engagement portion 29 of the intermediate member 20 on the side of the main hinge member 30 is exposed, and the contact portion 39b of the surface is in contact with the engagement surface 76a of the adjustment screw 70.

A through hole 85a is formed in the frictional engagement portion 85 coaxially with the housing cavity 81a, the through hole 85a has a smaller diameter than the housing cavity 81a and has a diameter substantially the same as the head 73 of the adjustment screw 70, and a pair of arcuate projections 85b and projections 85b are formed on the surface of the frictional engagement portion 85 on the side of the intermediate member 20 so as to be separated from each other in the front-rear direction D1 with the through hole 85a interposed therebetween.

A friction receiving hole 82a is formed in the 2 nd engaging portion 82 of the rotation suppressing member 80, the diameter of the friction receiving hole 82a is smaller than smaller than the operating portion 61 of the eccentric cam 60, and an annular bulging portion 82b surrounding the friction receiving hole 82a is formed on the surface of the 2 nd engaging portion 82 on the side of the intermediate member 20.

The assembly process of the intermediate member 20, the main hinge member 30, the eccentric cam 60, the adjustment screw 70, and the screwing suppressing member 80 configured as described above will be described mainly with reference to fig. 17. Before assembly, a caulking portion 75' having the same diameter as the washer mounting portion 74 is formed at the tip end of the washer mounting portion 74 of the adjusting screw 70.

The female screw portion 37 of the main hinge member 30 and the male screw portion 72 of the adjusting screw 70 screwed into the female screw portion 37 are received in the receiving cavity 81a of the 1 st receiving portion 81 of the rotation suppressing member 80, the head 73 of the adjusting screw 70 is inserted through the through hole 85a of the frictional engagement portion 85, and the operating portion 61 of the eccentric cam 60 is press-fitted into the frictional receiving hole 82a of the 2 nd receiving portion 82.

The intermediate member 20 is disposed along the rotation suppressing member 80, the cam portion 62 of the eccentric cam 60 is disposed between the pair of cam receiving portions 27 at , and the frictional engagement portion 85 of the rotation suppressing member 80 is prevented from being inserted into the receiving hole 28.

In the caulking process, the washer 77 is engaged by an annular step 73x at the boundary between the head 73 and the washer attachment portion 74, and the distance D between the step 73x and the engagement surface 76a of the inner end portion of the male screw portion 72 corresponds to the distance between the engagement surface 77a of the washer 77 and the engagement surface 76a of the inner end portion 76 of the male screw portion 72, and is substantially equal to the distance between the abutment portions 29b of the engagement portions 29.

The thickness T of the frictional engagement portion 85 of the rotation suppressing member 80 (the dimension from the flat surface on the side of the housing cavity 81a to the top surface of the projection 83b in the natural state) is larger than the distance D, and therefore, in the caulking process, the frictional engagement portion 85 is elastically compressed and deformed between the engagement surfaces 76a and 77a, and as a result, both surfaces of the frictional engagement portion 85 come into contact with the engagement surfaces 76a and 77a with pressing force, and therefore, the adjusting screw 70 is rotated while receiving the frictional resistance of the frictional engagement portion 85, and is prohibited from being rotated freely after the position adjustment, and as a result, the main hinge member 30 or fan 2 can stably maintain the adjusted position in the right-left direction D3.

Since the eccentric cam 60 is pressed into the friction receiving hole 82a of the rotation suppressing member 80, a friction action is exerted with the inner peripheral surface of the friction receiving hole 82a, in the present embodiment, since the thickness of the 2 nd engaging part 82 of the rotation suppressing member 80 (the thickness of the 2 nd engaging part 82 including the bulging part 82b in a natural state) is larger than the interval between the cam part 62 and the top plate part 31 of the main hinge member 30 determined by the insertion of the slide shaft 35 into the guide hole 26, the 2 nd engaging part 82 is elastically compressed, and a friction action is exerted between the 2 nd engaging part 82 and the cam part 62, and as a result, the eccentric cam 60 is rotated while receiving the frictional resistance of the 2 nd engaging part 82, and the rotation is prohibited after the position adjustment, and therefore, the main hinge member 30 or fan 2 can stably maintain the adjusted position in the front-rear direction D1.

The 1 st and 2

nd accommodation parts

81 and 82 can surely prevent the intermediate member 20 from coming into contact with the main hinge member 30 when positioning in the left-right direction D3. In particular, in the present embodiment, since the female screw portion 37 is housed in the housing cavity 81a of the 1 st housing portion 81, and the tip end of the female screw portion 37 can be reliably prevented from abutting against the intermediate member 20, the position adjustment in the front-rear direction D1 by the eccentric cam 60 is not hindered.

Embodiment 2 of the present invention is described below with reference to fig. 18 to 22. In the following embodiments, the structures that repeat the above-described methods are all labeled with the same reference numerals and are not described again. In embodiment 2, the intermediate member 20 is formed with a female screw portion 127 that protrudes toward the bottom pad (not shown).
