The wire winder 20 includes a small gear 21 that directly winds the wire 30, a large gear 22 that meshes with the small gear 21 as the small gear 21 moves in the axial direction, and a rotational force to the large gear 22. The operation lever 23 and the push-pull cable 24 installed between the small gear 21 and the operation lever 23 are mainly configured.

  The specific configuration of the wire winding mechanism 20 will be described. The wire winding mechanism 20 is accommodated in a housing 15 provided inside the instrument panel 4 and fixed to the upper and lower plates 15 a and 15 b of the housing 15. A small gear 21 is supported on the pair of upper and lower bearing portions 16 and 17 so as to be movable up and down. In the illustrated example, the large gear 22 is rotatably supported by a bearing portion 18 provided on the lower plate 15 b of the housing 15, but is rotatably supported by a bearing portion provided on the upper plate 15 a of the housing 15. May be.

  Here, the gear ratio between the small gear 21 and the large gear 22 is preferably 1: 1.5 to 1: 3, particularly 1: 2. This is because an operating force of 35N is required at the beginning of closing the side door 2, and 105N is required in balance to pull the hinge side panel portion, but the operating force of the operating lever 23 described later does not feel heavy until 50N. is there.

  An insertion hole 16a through which the push-pull cable 24 is inserted is formed in one bearing portion 16 that supports the small gear 21, and in the drawing, the upper bearing portion 16, and one end portion of the push-pull cable 24 is an operation lever 23 described later. The other end of the push-pull cable 24 is fixed to the shaft portion 21a of the small gear 21 via the insertion hole 16a. The other end of the wire 30 whose tip 31 is fixed to the side door 2 is fixed to the small gear 21, and the wire 30 is wound around the shaft 21 a of the small gear 21 by the rotation of the small gear 21.

  One end portion 25a of the strip 25 is fixed to the shaft portion 22a of the large gear 22, and the tip portion 25b of the strip 25 is fixed to the one end portion 26a of the wire 26 in a state where the strip 25 is wound around the shaft 25a. The other end portion 26b of the wire 26 is fixed to an operation lever 23 described later.

  A receiving portion 15c of the operation lever 23 is formed to protrude from the vehicle interior side of the housing 15, and the push-pull cable 24 and the cable 26 are drawn out from the inside of the housing 15 through the hollow of the receiving portion 15c. An operation lever 23 is attached to the operation lever receiving portion 15 c of the housing 15. The operation lever 23 includes a shaft portion 23a fitted in the operation lever receiving portion 15c and a head portion 23b pulled by an operator, and a switch button 27 is provided on the back side of the head portion. The switch button 27 includes a button portion 27a that can be pressed by the operator, and a shaft portion 27b that is recessed from the back side of the head portion 23b of the operation lever 23. A spring 28 is inserted between the shaft portion 27b of the switch button 27 and the front side of the operating lever 23. When the operator stops pressing the button portion 27a of the switch button 27, the button portion 27a is housed in the housing. Projects to the 15 side.

  An operation method when the side door 2 is closed by the side door closing device 10 configured as described above will be described. In the state where the side door 2 is opened, a person sitting in the passenger seat leans down slightly and pulls the operation lever 23 arranged on the lower side of the grab box in the direction of arrow A. At that time, the operation lever 23 is pulled toward the seated person while pushing the switch button 27 against the spring 28. Then, the operating force is transmitted to the push-pull cable 24, the small gear 21 descends along the axial direction, and the small gear 21 meshes with the large gear 22. At the same time, the operation lever 23 is pulled toward the seated person, so that the cable 26 fixed to the operation lever 23 is pulled rearward and the large gear 22 counterclockwise against the force of the ridge 25 ( Rotate in the direction of arrow B). Then, the small gear 21 rotates clockwise (in the direction of the arrow C), and the cable 30 is pulled in the direction of the arrow D and is wound around the small gear 21. Thereby, the side door 2 rotates in the closing direction around the hinge portion.

  When the side door 2 rotates to the extent that the hand can reach the pull handle 2a of the side door 2, the seated person can reach the side door 2 and can close the side door 2 by hand. At that time, the seated person stops pulling the operation lever 23. Then, the switch button 27 returns to the original state by the restoring force of the spring 28, and the operating force is not transmitted to the push-pull cable 24, so the small gear 21 rises along the axial direction and does not mesh with the large gear 22. . Further, since the large gear 22 pulls the cable 26 by the restoring force of the ridge 25, the operation lever 23 returns to the original position.

  Thus, the person sitting in the passenger seat can perform the closing operation of the side door 2 while sitting down by operating the operation lever 23 without moving the body greatly. The side door closing device 10 according to the present embodiment can be retrofitted to a grab box in the instrument panel 4 and can be deployed not only on a welfare vehicle but also on a normal vehicle.

  Although the embodiments have been described above, it is needless to say that the present invention can be implemented with appropriate modifications within the scope of the claims. For example, in the winding mechanism 20, the vertical positional relationship between the small gear 21 and the large gear 22 is not limited to the illustrated case, and may be reversed.
