     DETAILED DESCRIPTION 
     An illustrative embodiment of the present invention will be described with reference to  FIGS. 1 to 8 . As shown in  FIG. 1 , a vehicle seat  10  includes a seat cushion  11  and a seat back  12  erected in the rear of the seat cushion  11 . An elevating device  17 , a rail  13 , and an anchor member (body member)  14  are installed below the seat cushion  11 . 
     The rail  13  includes a lower rail  13   a  attached on a flower surface of a vehicle and an upper rail  13   b  movably mounted on the lower rail  13   a , as shown in  FIG. 1 . The anchor member  14  and the elevating device  17  are installed on the upper rail  13   b . The elevating device  17  is configured to elevate the seat cushion  11  with respect to the upper rail  13   b.    
     As shown in  FIGS. 2 and 3 , the anchor member (body member)  14  is made of metal, and includes a base portion  14   a  attached on the top surface of the upper rail  13   b , an outer-side piece  14   b  extending upwards from the outer periphery of the base portion  14   a , and an inner-side piece  14   c  extending upwards from the inner periphery of the base portion  14   a . A bolt  15   d  is attached on the rear portion of the outer-side piece  14   b , and the seat belt  15  is connected to the bolt  15   d.    
     The seat belt  15  includes an arm  15   a  and a buckle  15   b , as shown in  FIG. 3 . The arm  15   a  is made of metal, and is rotatably attached with respect to the bolt  15   d  by a nut  15   c . The buckle  15   b  releasably holds a tongue (not shown) inserted into the buckle  15   b . The tongue is attached to a belt connected to a vehicle body. Therefore, the tongue is held by buckle  15   b , and as a result, the seat belt is connected to the anchor member  14 . 
     In the buckle  15   b , there is installed a switch  15   e  which is capable of detecting whether the tongue is inserted into the buckle  15   b , as shown in  FIG. 3 . The switch  15   e  is connected with an electric wiring  16  extending from the buckle  15   b  and connected with a control device installed in a vehicle via the electric wiring  16 . 
     The electrical wiring (wire harness)  16  includes a plurality of electric wires  16   b  and a cover  16   a , as shown in  FIGS. 3 and 7 . The cover  16   a  having a cylindrical shape covers the plurality of electric wires  16   b . The cover  16   a  alternately includes a plurality of convex portions  16   a   1  that are convex in a diameter direction and a plurality of concave portions  16   a   2  that are concave in the diameter direction. The electric wiring  16  is attached on the anchor member  14  by the attaching member  1 . 
     The attaching member  1  is made of a resin and integrally includes an attaching part  2 , a protection part  3 , and a holder part  4 , as shown in  FIGS. 3 and 4 . The protection part  3  having an L-shaped cross section integrally includes a first cover portion  3   a  and a second cover portion  3   b . The second cover portion  3   b  extends in parallel to and covers an outer surface  14   b   3  of the outer-side piece  14   b  of the anchor member  14 . The first cover portion  3   a  projects from the upper periphery of the second cover portion  3   b  to cover an upper edge  14   b   1  of the outer-side piece  14   b  from above. 
     The attaching part  2  includes a first piece  2   a  and a second piece  2   b  projecting from the second cover portion  3   b  in a projecting direction orthogonal to an extending direction for the second cover portion  3   b , as shown in  FIGS. 5 and 6 . The tip end of the first piece  2   a  is formed with a claw  2   a   1  which projects to the upper side opposite to the second piece  2   b . The second piece  2   b  has an arc-shaped bottom surface which becomes convex to the lower side opposite to the first piece  2   a . While the first piece  2   a  is elastically deformed, the attaching part  2  is inserted into an attachment hole  14   b   2  of the outer-side piece  14   b  of the anchor member  14  in the projecting direction. The shape of the first piece  2   a  is then elastically restored and claw  2   a   1  is locked on an inner surface  14   b   4  of the outer-side piece  14   b . As a result, the attaching member  1  is attached on the anchor member  14 . 
     The first cover portion  3   a  is formed with a pair of locking parts  5 , as shown in  FIGS. 4 and 6 . The locking parts  5  project downwards from front and rear sides of the first cover portion  3   a . The locking parts  5  project toward the inner surface  14   b   4  of the outer-side piece  14   b  and cooperate with the second cover portion  3   b  to prevent the attaching member  1  from moving in a width direction with respect to the anchor part  4  while sandwiching the outer- side piece  14   b  with the second cover portion  3   b.    
     The holder part  4  includes a first holder piece  4   a  and a second holder piece  4   b , as shown in  FIGS. 5 and 6 . The first holder piece  4   a  extends upwards from the center of an inner end of the first cover portion  3   a . The second holder piece  4   b  is connected to the tip end of the first holder piece  4   a  through a hinge portion  4   c . Since the hinge portion  4   c  is thinner than the first holder piece  4   a , the hinge portion  4   c  is configured to be easily deformed. The second holder piece  4   b  is formed with a locking claw  4   d  at the tip end portion thereof to be engaged with a locking claw  3   a   1  formed at the first cover portion  3   a.    
     As shown in  FIGS. 5 and 6 , the second holder piece  4   b  is rotated with respect to the first holder piece  4   a  to engage the locking claw  4   d  with the locking claw  3   a   1 . The electrical wiring  16  is interposed between the first holder piece  4   a  and the second holder piece  4   b . The electrical wiring  16  is held onto the upper side of the protection part  3  by the holder part  4 . 
     As shown in  FIGS. 7 and 8 , claws  4   a   1  and  4   b   1  are formed at the front and rear end portions of the first holder piece  4   a  and the second holder piece  4   b . The claws  4   a   1  and  4   b   1  enter a concave portion  16   a   2  of the cover  16   a  of the electric wiring  16  to prevent the electric wiring  16  from moving in forward and backward directions with respect to the holder part  4 . 
     The attaching member  1  is attached to the left side of the vehicle seat  10 , as shown in  FIG. 1 . However, the attaching member  1  may be used at the right side of the vehicle seat  10 . In this case, the attaching member  1  may be used by reversing a direction from left to right. As a result, the attaching member  1  may be used at both left and right sides of the vehicle seat  10  with the same shape. 
     As described above, the attaching member  1  integrally includes the attaching part  2  attached on an anchor member (body member)  14 , the protection part  3  which covers the edge  14   b   1  of the anchor member (body member)  14 , and the holder part  4  which holds the electric wiring  16 , as shown in  FIG. 2 . 
     Therefore, the edge  14   b   1  of the anchor member (body member)  14  is covered by the protection part  3 . As a result, it is possible to prevent the electric wiring  16  from being damaged due to contact with the edge  14   b   1  of the anchor member (body member)  14 . The attaching member  1  integrally includes the attaching part  2 , the protection part  3 , and the holder part  4 . Accordingly, while the number of components does not increase, the electric wiring  16  can be attached on the anchor member (body member)  14 , and it is also possible to protect the electric wiring  16  from the edge  14   b   1  of the anchor member (body member)  14 . 
     As shown in  FIG. 2 , the protection part  3  is in contact with the anchor member (body member)  14 . The attaching part  2  and the holder part  4 , respectively, extend from the protection part  3 . Accordingly, when the electric wiring  16  vibrate, the holder part  4  may vibrate around the protection part  3 . In this regard, the attaching member  1  can be prevented from vibrating with respect to the anchor member (body member)  14  by the protection part  3  and the attaching part  2 . Therefore, the vibration of electric wiring  16  can be suppressed by the attaching member  1 . 
     As shown in  FIG. 2 , the attaching part  2  is attached on the body member which is the anchor member  14  connected with the seat belt  15 . The protection part  3  covers the upper edge  14   b   1  of the anchor member  14 . The holder part  4  holds the electric wiring  16  extending from the seat belt  15  at the upper side of the anchor member  14 . 
     That is, since the electric wiring  16  extends from the seat belt  15 , the electric wiring  16  comes close to the anchor member  14 . The anchor member  14  is made of a relatively rigid material to tolerate the force applied from seat belt  15 . For this reason, since the edge  14   b   1  of the anchor member  14  is made of a rigid material, it is relatively difficult to deform edge  14   b   1 , thereby easily damaging a member that contacts the edge. However, the attaching member  1  covers the upper edge  14   b   1  of the anchor member  14 , and further, holds the electric wiring  16  onto the upper side of the anchor member  14 . Therefore, the electric wiring  16  can be suppressed from being in contact with the upper edge  14   b   1  of the anchor member  14 . Thus the electric wiring  16  can be suppressed from any damage by anchor member  14 . 
     While the present invention has been shown and described with reference to certain illustrative embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. 
     For example, the attaching member  1  may be used to attach another electric wiring on another body member. Another electric wiring is, for example, an electric wiring connected to a driving device such as a motor for changing the position or shape of the vehicle seat  10 . The body member is, for example, a frame of the seat cushion or seat back  12 , or a member attached on the frame. 
     Further, the protection part  3  may cover another edge of the body member, rather than the upper edge of the body member such as the anchor member  14 . The protection part  3  may have only the first cover portion  3   a , without the second cover portion  3   b . In this case, the attaching part  2  extends from the first cover portion  3   a.    
     Further, the holder part  4  may extend to the side (outer side or inner side) of the protection part  3 , rather than the upper side of the protection part  3 . The holder part  4  may be configured, for example, to have an opening having a C-shaped cross section and elastically hold an electric wiring by receiving the electric wiring from the opening.
