A third side L-shaped projection portion  112   b  has the same composition (same shape) as the first side L-shaped projection portion  112   a . The third side L-shaped projection portion  112   b  therefore may include a third bulge  112   d  that also projects in the direction of the first intermediate slide member  131   a.    
         [0027]    The first side slide rail  11   a  shown in  FIG. 2  is fixed on the left side of the inside of the chassis  31 in a view of a back portion of the side chassis  31 , as shown in  FIG. 5 .  FIG. 4  illustrates the entire composition of a second side slide rail  11   b  as it would be fixed or mounted on the right side of the inside of the chassis  31  (see  FIG. 6 ). The second side slide rail  11   b  may include three telescoping slide members including a second chassis-engaging slide member  111   b , a second unit-engaging slide member  121   b , and a second intermediate slide member  131   b . The second chassis-engaging slide member  111   b  is able to slide back and forth in the direction A over the outside of the second intermediate slide member  131   b . The second unit-engaging slide member  121   b  is able to slide back and forth in the direction A into and out of the second intermediate slide member  131   b . One side of the second chassis-engaging slide member  111   b  may include two side L-shaped projection portions  112   f  and  112   g . The second side L-shaped projection portion  112   f  and the fourth side L-shaped projection portion  112   g  have the same composition (same shape) as the first side L-shaped projection portion, and the second side L-shaped projection portion  112   f  may include a second bulge  112   h , while the fourth side L-shaped projection portion  112   g  may include a fourth bulge  112   i . Both of these two bulges project in the direction of the second intermediate slide member  131   b . The side of the second unit-engaging slide member  121   b  may include three clincher holes  132   a  for fixing by a clincher  21   b  such as a screw or bolt, to a side of a unit that is to be housed in a chassis as described below. 
         [0028]    As shown in  FIG. 5 , the side of the chassis  31  may include a first fitting hole  311   a  and a third fitting hole  311   b  created by punching. The distance of the first fitting hole  311   a  to the third fitting hole  311   b  is identical to the distance of the first side L-shaped projection portion  112   a  to the third side L-shaped projection portion  112   b  arranged on the first chassis-engaging slide member  111   a . The first and third fitting hole  311   a ,  311   b  may include respectively a first cutout  311   c  and a third cutout  311   d  each projecting in the same direction as the first and third bulges  112   c  and  112   d , in the back side portion of the chassis  31 . As shown in  FIG. 6 , the right side of the inside of the chassis  31  may include a second fitting hole  311   f  and a fourth fitting hole  311   g  which are of the same composition (same shape) as the first fitting hole  311   a  and the third fitting hole  311   b  of the left side of the chassis  31 . The second fitting hole  311   f  may include a second cutout  311   h , and the fourth fitting hole  311   g  may include a fourth cutout  311   i.    
         [0029]    The step to fix the first side slide rail  11   a  to the chassis  31  will be described with reference to  FIG. 5 . In  FIG. 5 , the upper left side is the front side of the chassis  31 , and the lower right side is the back side of the chassis  31 . 
         [0030]    Inside of the chassis  31 , the first side slide rail  11   a  is moved in the direction of arrow B, so that first side L-shaped projection portion  112   a  and third side L-shaped projection portion  112   b  are positioned at the first fitting hole  311   a  and the third fitting hole  311   b , respectively. The first side slide rail  11   a  is moved in the direction of arrow C, so that the first side L-shaped projection portion  112   a  and the third side L-shaped projection portion  112   b  are inserted into the first fitting hole  311   a  and the third fitting hole  311   b , respectively. The first side slide rail  11   a  is moved in the direction of arrow D until the first side L-shaped projection portion  112   a  and the third side L-shaped projection portion  112   b  contact the lower end of the first fitting hole  311   a  and the third fitting hole  311   b . The first side slide rail  11   a  is moved in the direction of arrow E, and the first bulge  112   c  of the first side L-shaped projection portion  112   a  and the third bulge  112   d  of the third side L-shaped projection portion  112   b  are hooked and fixed at the first cutout  311   c  of the first fitting hole  311   a  and the third cutout  311   d  of the third fitting hole  311   b , respectively. When the holding force between the first and third bulges  112   c ,  112   d  and the first and third cutouts  311   c ,  311   d  is lacking, they also may be fixed by clinchers. Also, unit  41  is fixed to the first side slide rail  11   a  by a clincher  21   a  and a clincher hole  122   a  of the first unit-engaging slide member  121   a.    
         [0031]    As shown in  FIG. 6 , the steps to fix the second side slide rail  11   b  to the chassis  31  are same of the steps to fix the first side slide rail  11   a  to the chassis  31 . The second side slide rail  11   b  can be fixed to the chassis  31  by moving it in an order of arrow B, C, D, E, after the side L-shaped projection portion of the second side slide rail  11   b  is inserted into the fitting hole of the chassis  31 . 
         [0032]    As described above, according to the slide rail structure of the first embodiment, the side of the first side slide rail  11   a  that contacts the chassis  31  may include two side L-shaped projection portions created by bending work from the first body portion after U-shaped punches are made, and these side L-shaped projection portions each with its cutout, are arranged in the back portion of a side of the chassis  31 . The side of the second side slide rail  11   b  may include the second side L-shaped projection portion  112   f  which has the second bulge  112   h , and the fourth side L-shaped projection portion  112   g  which has the fourth bulge  112   i , as with the first side slide rail  11   a . The one side of the chassis  31  may include the first fitting hole  311   a  which has the first cutout  311   c , and the third fitting hole  311   b  which has the third cutout  311   d  in the back portion of the side of the chassis  31  to insert and hook the first side L-shaped projection portion  112   a  and the third side L-shaped projection portion  112   b . The other side of the chassis  31  may include the second fitting hole  311   f  which has the second cutout  311   h , and the fourth fitting hole which has the fourth cutout  311   i  in the back portion of the side of the chassis  31  to insert and hook the second side L-shaped projection portion  112   f  and the fourth side L-shaped projection portion  112   g , respectively. Therefore, the first side slide rail  11   a  can be fixed to the chassis  31  only to insert and hook the first side L-shaped projection portion  112   a  to the first fitting hole  311   a , and the third side L-shaped projection portion  112   b  to the third fitting hole  311   b . And to fix the second side slide rail  11   b  to the chassis  31  the worker has only to insert and hook the second side L-shaped projection portion  112   f  to the second fitting hole  311   f , and the fourth side L-shaped projection portion  112   g  to the fourth fitting hole  311   g . Therefore, the worker does not need to insert his or her hands into the chassis  31  in order to screw a clincher, is able to assemble the slide rails easily, thereby to reduce the likelihood of dropping the first side slide rail  11   a  and the second side slide rail  11   b  while at work. 
         [0033]    The first embodiment is described as having first and third side L-shaped projection portions  112   a ,  112   b  created by bending work from the body portion after the punching of the side of the first chassis-engaging slide member  111   a . But instead the L-shaped projections portions may be welded to the side of the first chassis-engaging slide member  111   a . Also, while the first side slide rail  11   a  is described to include the first chassis-engaging slide member  111   a , the first unit-engaging slide member  121   a  and the first intermediate slide member  131   a , the first side slide rail  11   a  may in an alternative embodiment include only the first chassis-engaging slide member  111   a  and the first unit-engaging slide member  121   a.

The side of the second side slide rail  21   b  may include the second side L-shaped projection portion  212   f  which has the second bulge  212   h , and the fourth side L-shaped projection portion  212   g  which has the fourth bulge  212   i , as with the first side slide rail  21   a . The one side of the chassis  32  may include the first fitting hole  321   a  which has the first cutout  321   c , and the third fitting hole  321   b  which has the third cutout  321   d  in the front portion of the side of the chassis  32  to insert and hook the first side L-shaped projection portion  212   a  and the third side L-shaped projection portion  212   b . The other side of the chassis  32  may include the second fitting hole  321   f  which has the second cutout  321   h , and the fourth fitting hole which has the fourth cutout  321   i  in the front portion of the side of the chassis  32  to insert and hook the second side L-shaped projection portion  212   f  and the fourth side L-shaped projection portion  212   g . Therefore, the first side slide rail  21   a  can be fixed to the chassis  32  only to insert and hook the first side L-shaped projection portion  212   a  to the first fitting hole  321   a , and the third side L-shaped projection portion  212   b  to the third fitting hole  321   b . And to fix the second side slide rail  12   b  to the chassis  32  the worker has only to insert and hook the second side L-shaped projection portion  212   f  to the second fitting hole  321   f , and the fourth side L-shaped projection portion  212   g  to the fourth fitting hole  321   g . Therefore, the worker does not need to insert his or her hands into the chassis  32  in order to screw a clincher, and is able to assemble the slide rails easily without dropping the first side slide rail  12   a  and the second side slide rail  12   b  while at work. 
         [0042]    As described above, the first and third sides L-shaped projection portions  212   a ,  212   b  are created by bending work from the first body portion after the punching of the side of the first chassis-engaging slide member  211   a . However, as in the first embodiment the side L-shaped projection portions instead may be welded to the side of the first chassis-engaging slide member  211   a . Also, while the first side slide rail  12   a  is described to include the first chassis-engaging slide member  211   a , the first unit-engaging slide member  221   a  and the first intermediate slide member  231   a , the first side slide rail  12   a  may include only the first chassis-engaging slide member  211   a  and the first unit-engaging slide member  221   a.    
         [0043]    The slide rail structure of the second embodiment described above, in addition to having the effects of the first embodiment, allows the slide rail to be fixed by the first side slide rail  12   a  and the second side slide rail  12   b  moving in only one direction, and the worker is able to work more easily, and can reduce the likelihood that he or she may drop and break the first side slide rail  12   a  and the second side slide rail  12   b  while at a work. 
         [0044]    The first side slide rail  12   a  and the second side slide rail  12   b  can be arranged in the chassis  32  by moving them in one direction. Therefore the first side slide rail  12   a  and the second side slide rail  12   b  do not need to enter the back of the chassis  32  to be fixed, and it is possible to make the depth of the chassis  32  smaller. 
       Other Variation 
       [0045]    According to the above explanation of the first embodiment and the second embodiment, the pair of slide rails each may include two side L-shaped projection portions, and the chassis may include two fitting holes on each side, but the number of them on each side may be more than three or limited to one. 
         [0046]    As shown in  FIG. 12 , if in addition a taper part  112   t  is arranged at the top of the first side L-shaped projection portion  112   a  and the third side L-shaped projection portion  112   b  of the first embodiment, the first side slide rail  11   a  is more easily fixed on the chassis  31 . 
         [0047]    Similarly as shown in  FIG. 13 , if in addition a taper part  212   t  is arranged at the top of the first side L-shaped projection portion  212   a  and the third side L-shaped projection portion  212   b  of the second embodiment, the first side slide rail  12   a  is more easily fixed on the chassis  32 .
