  The harness 5 is fixed to the protrusion 4 via a harness clip 6. The harness clip 6 is formed of a flexible resin material, and includes a base portion 61, a surrounding bending portion 63, and a locking portion 65. As shown in FIG. 6, the base 61 has a flat shape. The outer shape of the base portion 61 in plan view is smaller than the pedestal portion 41 of the protrusion 4 and larger than the through hole 47 formed in the pedestal portion 41. The surrounding portion 63 is provided on one side surface of the base portion 61, and the locking portion 65 is provided on the other side surface of the base portion 61.

  An end portion of the surrounding bending portion 63 is formed so as to be detachable with respect to the base portion 61. When the end portion of the bendable portion 63 is locked to the base portion 61, the bendable portion 63 has an annular shape and can bend the harness 5. The outer peripheral surface of the harness 5 is constituted by a corrugated tube. The corrugated tube is made of a flexible resin material and has a large number of annular grooves. A part of the surrounding bending portion 63 surrounding the harness 5 is fitted into the groove of the corrugated tube, and the harness 5 is fixed.

  The locking portion 65 is formed so as to shrink when an external force is applied and to expand when the external force is removed. When the locking portion 65 is pushed into the through hole 47 of the protrusion 4 from above, the locking portion 65 comes into contact with the peripheral edge of the through hole 47 and can be reduced and inserted through the through hole 47. After the insertion, the contact with the periphery of the through hole 47 is released, the locking portion 65 expands, and locks around the through hole 47 as shown in FIG.

After the insertion, the snap fit clip 45 is enlarged and locked to the periphery of the through hole 21 and attached to the side frame 2.

  When the side cover 3 is fixed to the side frame 2, a space S is formed between them. The protrusions 4 of the side cover 3 are disposed so as to protrude into the space S, and the width of the space S (that is, the dimension of the space S in the left-right direction) is kept constant. The harness 5 is disposed in the space S so as to extend in the front-rear direction.

  Next, the function and effect produced by the seat 1 will be described.

  According to the configuration of the seat 1, the protrusion 4 protrudes from the cover body 31, and the harness 5 is fixed to the protrusion 4. A snap fit clip 45, which is a portion to be attached to the side frame 2, is provided at the tip portion 43 of the protrusion 4. Therefore, according to the above configuration, since the harness 5 can be fixed in the vicinity of the snap-fit clip 45, the harness 5 having a curved hook is placed between the snap-fit clip 45 and the frame 2 when the side cover 3 is fixed. Arrangement can be suppressed. As a result, it is possible to suppress biting of the harness 5 between the snap fit clip 45 and the frame 2.

  The seat 1 includes a harness clip 6 that surrounds the harness 5. A through hole 47 that is a clip fixing portion to which the harness clip 6 is fixed is formed in the protrusion 4.

  According to the above configuration, the harness 5 is fixed to the protrusion 4 via the harness clip 6. Therefore, even when the harness 5 is relatively thick, the portion of the projection 4 used for fixing the harness 5 (that is, the through hole 47) can be reduced. As a result, the protrusion 4 can be reduced in size.

  The protrusion 4 has a pedestal portion 41 connected to the cover main body 31. The width dimension W <b> 1 of the pedestal portion 41 is larger than the width dimension W <b> 2 of the tip end portion 43. A through hole 47 serving as a clip fixing portion is formed in the pedestal portion 41.

  According to the said structure, it becomes possible to fix the harness clip 6 reliably in the base part 41 of the protrusion 4 with a comparatively large width dimension. On the other hand, since the front end portion 43 of the protrusion 4 has a relatively small width dimension, it is possible to suppress the space S formed between the side cover 3 and the side frame 2 from being randomly occupied by the protrusion 4. That is, according to the said structure, it becomes possible to utilize effectively the space S formed between the side cover 3 and the side frame 2, fixing the harness clip 6 reliably.

  The clip fixing portion is a through hole 47 into which a part of the harness clip 6 is inserted.

  According to the above configuration, the harness clip 6 can be fixed with a simple configuration.
