[0014] The molding material 51 has fitting grooves 51d, 51d formed on the inside of the side walls 51b, 51b on the indoor side of the decorative wall 51a, and a rib 51e protruding toward the indoor side is provided on the indoor side surface at the center in the left-right direction of the decorative wall 51a. The molding material 51 may have double-sided tape 511 attached in advance to the indoor side surfaces of the left and right mounting walls 51c, 51c.

[0015] As shown in Figures 3(c), 4 and 5, the end cap 6 has a cover portion 61 that covers the end of the molding material 51, and an insertion wall 62 that extends inward from the inner surface of the cover portion 61.

[0016] The cover portion 61 has a shape that matches the cross-sectional shape of the molding material 51, and has a planar shape consisting of a curved exterior edge with two peaks on the exterior side and a straight interior edge that matches the panel material 1b of the door body 1, which are connected at the left and right side edges.

[0017] The insertion wall 62 has a positioning wall 62a protruding from one surface of the cover portion 61 along the indoor side edge of the cover portion 61, sight walls 62b, 62b connected in the left-right direction from the left and right ends of the positioning wall 62a and shifted toward the outdoor side, and fitting walls 62c, 62c connected to the left and right ends of the sight walls 62b, 62b and bent toward the outdoor side, respectively.

[0018] In addition, the insertion wall 62 may be provided with a press-in protrusion 62f near the left and right ends of the left and right viewing walls 62b, 62b and / or on the left and right side surfaces of the fitting walls 62c, 62c, which is pressed into the fitting groove portion 51d of the molding material 51 when fitted to the molding material 51. Further, the insertion wall 62 may be formed such that all or some of the lower ends of the positioning wall 62a, the sight walls 62b, 62b, and the fitting walls 62c, 62c are tapered to facilitate smooth fitting into the molding material 51.

[0019] The decorative molding 5 is formed by inserting the insertion wall 62 of the end cap 6 from the upper and lower ends of the molding material 51 and pressing the mating walls 62c, 62c of the end cap 6 into the mating groove portions 51d, 51d of the molding material 51, and is attached to the door body 1 by adhering the left and right mounting walls 51c, 51c of the molding material 51 to the exterior side surface of the door body 1 with double-sided tape or the like. In addition, the decorative molding 5 may have a convex portion 62e formed on the outdoor side surface of the positioning wall 62a of the end cap 6, and the convex portion 62e of the end cap 6 inserted into the molding material 51 may be abutted against the rib 5d of the molding material 51 to prevent crushing at the end of the molding material 51.

[0020] As described above, the decorative molding 5 is formed by the molding material 51 and the end cap 6, and is adhesively fixed to the exterior side of the door body 1. However, in the front door of this embodiment, a positioning part 7 is provided on the door body 1, and the decorative molding 5 is attached using the positioning part 7, making it easy to position the decorative molding 5 relative to the door body 1 and making manufacture easier. The structure for positioning the decorative molding 5 attached to the exterior side surface of the door body 1 will be further described below.

[0021] (Positioning by positioning parts) As shown in Figures 2, 3(a) and 5, the door body 1 of this embodiment has positioning parts 7 attached to the upper end and lower end on the exterior surface, corresponding to the mounting positions of the decorative moldings 5 ​​arranged in a row in the left-right direction.

[0022] The positioning part 7 of the front door of this embodiment is made of a resin material and is a circular button-shaped component as shown in Figures 3(d) and 5, with a mounting hole 7a formed through the center of the circle and a recess 7b formed in the central part of the exterior side so as to surround the mounting hole 7a. The positioning part 7 is fixed to the exterior-side plate material 1b of the door body 1 by a rivet 72 or the like through the mounting hole 7a, and the head of the rivet 72 fits into the recess 7b of the positioning part 7.

[0023] On the other hand, in the decorative molding 5 of this embodiment, as shown in Figures 3(c), 4, and 5, a positioning hole (positioning portion) 62d that is long in the longitudinal direction of the decorative molding 5 is formed in the positioning wall 62a of the insertion wall 62 of the end cap 6, penetrating in the projection direction. The end cap 6 fitted to the molding material 51 has a positioning hole (positioning portion) 62d exposed to the inside of the room from between the left and right mounting walls 51c, 51c of the molding material 51, and the decorative molding 5 has positioning holes (positioning portions) 62d, 62d formed on the indoor side surfaces of the upper and lower ends.

[0024] When fixing the decorative molding 5 to the exterior side surface of the door body 1, as shown in Figure 3 (e), upper and lower positioning parts 7 attached to the door body 1 are fitted into positioning holes (positioning parts) 62d, 62d formed at the upper and lower ends of the interior side surface of the decorative molding 5, and the left and right mounting walls 51c, 51c of the molding material 51 are adhered to the door body 1.

[0025] (Effects of the opening device of the embodiment) In the front door of this embodiment, a positioning part 7 is attached to the door body 1, and the decorative molding 5 can be attached in accordance with the positioning part 7, so that the decorative molding 5 can be easily positioned relative to the door body 1, the spacing between the left and right sides can be easily made uniform, and installation can be simplified.

[0026] In the front door of this embodiment, the positioning part 7 to be attached to the door body 1 is formed in a circular shape, and the positioning portion 62d into which the positioning part 7 is fitted is formed long in the vertical direction. This means that there is no need to be concerned about the orientation when attaching the positioning part 7, and even if an error occurs in the attachment of the positioning part 7, it can be absorbed by the long hole, making it easy to manufacture the front door. In addition, in the front door of this embodiment, since the positioning part 7 is formed in a circular shape, even when the decorative molding 5 is placed diagonally or horizontally to the door body 1, the decorative molding 5 can be easily installed without having to worry about the installation of the positioning part 7, making construction simple. Furthermore, by forming the positioning portion 62d into which the positioning part 7 is fitted as a long hole that is long in the longitudinal direction of the decorative molding 5, it is possible to provide a gap between the positioning portions 62d of the upper and lower end caps 6 when the decorative molding 5 is positioned at an angle, and thus the decorative molding 5 can be positioned at an angle.

[0027] The front door of this embodiment is positioned by inserting the positioning part 7 attached to the door body 1 into the positioning hole (positioning portion) 62d of the end cap 6 arranged at the lower end of the decorative molding 5, so that the vertical force applied to the decorative molding 5 can be supported by the positioning part 7, reducing the burden on the adhesive part and improving durability.

[0028] In the front door of this embodiment, the positioning part 7 is fixed by rivets 72 to the plate material 1b made of steel or the like on the exterior side of the door body 1. This prevents large holes from being formed in the plate material 1b of the door body 1. Furthermore, the hole can be sealed by the positioning part 7 and rivets 72, preventing flames and smoke from penetrating through the hole and improving fire resistance.

[0029] (Other embodiments) In the opening device of the present invention, the positioning portion 62d provided in the decorative molding 5 is formed by a long hole penetrating the positioning wall 62a of the end cap 6, but the positioning portion 62d may also be formed by a recess provided on the indoor side of the positioning wall 62a, and its configuration is not limited as long as it has a shape and structure that can accommodate the positioning part 7.

[0030] Moreover, the positioning component 7 attached to the door main body 1 may be provided on at least one of the upper end and the lower end of the surface of the door main body 1 . In addition, it goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples. [Explanation of symbols]
