Further, when the rotational position of the first confirmation line 88 coincides with the camshaft 74 circumferential position of the second confirmation line 90 on the left side surface of the case 34 </ b> A, the rack 78 is slid to a predetermined sliding position, and the camshaft 74. Is rotated to a predetermined rotation position, the connecting plate 75 and the cam 76 are rotated to a predetermined rotation position, and the cam 76 is rotated to the left side of the predetermined (front, upper or rear) driven clutch 68. At the same time, the rotation shaft 84 is rotated to a predetermined rotation position, and the rotation unit 82 is rotated to a predetermined rotation operation position (“reclining position”, “lifting position” or “sliding position”).

  For this reason, the switch 80 is assembled to the clutch unit 34 fixed inside the cushion frame 16 and the switch 80 is attached to the outside of the left end of the cushion frame 16 (the posture (rotational position) of the switch 80 with respect to the clutch unit 34 is regulated). However, when the switch 80 is assembled to the clutch unit 34), the rotational position of the first confirmation line 88 coincides with the position of the second confirmation line 90 in the circumferential direction of the camshaft 74, and the rotating portion 82 is at a predetermined rotational operation position. The right part of the rotating shaft 84 is inserted into the upper portion of the rack chamber 40 of the case 34 </ b> A and the gear 84 </ b> A of the rotating shaft 84 is engaged with the rack teeth 78 </ b> B of the rack 78.

  Thereby, the slide position of the rack 78, the rotation position of the cam shaft 74, the rotation position of the connecting plate 75, the rotation position of the cam 76, the rotation position of the rotation shaft 84, and the rotation operation position of the rotation unit 82 can be easily performed. Thus, the switch 80 can be assembled to the clutch unit 34 without error, and erroneous assembly of the switch 80 to the clutch unit 34 can be prevented. Therefore, by rotating the rotating portion 82 to the “reclining position”, “lifting position” or “sliding position”, the cam 76 is accurately placed on the left side of the driven clutch 68 of the front, upper or rear clutch mechanism 54. Can be rotated.

  When the switch 80 is assembled to the clutch unit 34, if the rotational position of the first confirmation line 88 does not coincide with the circumferential position of the cam shaft 74 on the second confirmation line 90, the tool on the left edge of the cam shaft 74 By inserting a tool into the hole 92 and rotating the camshaft 74, the rotational position of the first confirmation line 88 is matched with the circumferential position of the second confirmation line 90 in the camshaft 74. Thereby, the rotational position of the camshaft 74 can be easily adjusted to a predetermined rotational position, and the slide position of the rack 78, the rotational position of the camshaft 74, the rotational position of the connecting plate 75, and the rotational position of the cam 76, The rotation position of the rotation shaft 84 and the rotation operation position of the rotation unit 82 can be more easily matched.

  In the present embodiment, the first confirmation line 88 is provided on the left end edge of the camshaft 74 and the second confirmation line 90 is provided on the left side surface of the case 34A. However, the rack 78, the camshaft 74, and the connecting plate 75 are provided. In addition, a first confirmation line 88 is provided on at least one of the cams 76, a second confirmation line 90 is provided on the inner surface of the case 34A, and a confirmation part (transparent window or through-hole) is formed on the peripheral wall of the case 34A. ) May be formed.

  In this case, the first confirmation line 88 and the second confirmation line 90 can be visually recognized (confirmed) from the outside of the case 34A through the confirmation unit, and the position of the first confirmation line 88 is the position of the second confirmation line 90. Thus, the rack 78 is slid to a predetermined slide position, the camshaft 74 is rotated to a predetermined rotation position, the connecting plate 75 and the cam 76 are rotated to a predetermined rotation position, and the cam 76 is rotated. Is rotated to the left side of a predetermined (front, upper, or rear) driven clutch 68.

  Furthermore, in the present embodiment, the adjusting means (tool hole 92) is provided at the left end edge of the camshaft 74, but at least one of the rack 78, the camshaft 74, the connecting plate 75, and the cam 76 can be provided with adjusting means. That's fine.

  In the present embodiment, the adjusting means (tool hole 92) is provided at the left end edge of the camshaft 74, but an adjusting hole as an adjusting means may be formed through the peripheral wall of the case 34A.

  In this case, when the switch 80 is assembled to the clutch unit 34, the locking member is inserted (inserted) into the adjustment hole and inserted into the case 34 </ b> A, so that the locking member becomes the rack 78, the camshaft 74, At least one of the connecting plate 75 and the cam 76 is locked. As a result, the slide position of the rack 78 is locked (adjusted) at a predetermined slide position, the rotational position of the camshaft 74 is locked (adjusted) at a predetermined rotational position, and the rotational positions of the connecting plate 75 and the cam 76 are adjusted. Is locked (adjusted) at a predetermined rotation position, and the rotation position of the cam 76 is locked to the left side of the predetermined (front, upper, or rear) driven clutch 68. Thereafter, in a state where the rotating portion 82 of the switch 80 is rotated to a predetermined rotation operation position, the right portion of the rotating shaft 84 of the switch 80 is inserted into the upper portion of the rack chamber 40 of the case 34A, and the gear 84A of the rotating shaft 84 is inserted. Is engaged with the rack teeth 78B of the rack 78. Thereby, the slide position of the rack 78, the rotation position of the cam shaft 74, the rotation position of the connecting plate 75, the rotation position of the cam 76, the rotation position of the rotation shaft 84, and the rotation operation position of the rotation unit 82 can be easily performed. Can be adapted. After the switch 80 is assembled to the clutch unit 34, the locking member is removed from the case 34A (adjustment hole), and at least one of the rack 78, the camshaft 74, the connecting plate 75, and the cam 76 is locked by the locking member. Release the stop.

  Further, in the present embodiment, three actuating means (the reclining mechanism 22, the lifting mechanism 28, and the slide mechanism 32) and three clutch mechanisms 54 are provided, but two or four or more actuating means and clutch mechanisms 54 are provided. May be. In this case, the switch 80 is operated to rotate the front portion of the seat cushion 14 in the vertical direction with respect to the rear portion, or at least a part (lower portion or the like) of the seat back 18 is moved in the front-rear direction. May be moved to.

  In addition, the present invention can be implemented with various modifications without departing from the scope of the invention. Needless to say, the scope of rights of the present invention is not limited to the above embodiment.
