By the way, the inner handle 15 is rotatably supported by the inner seat plate member 9 having the decorative cylinder 14, but the inner handle 15 of the embodiment normally has a handle portion 15a that is either in a horizontal state or a vertical state. The horizontal shaft portion 15b is provided in a substantially orthogonal state to or integrally connected to the handle portion, and the horizontal shaft portion 15b is a slightly long cylindrical tube, A horizontal fitting hole 16 for the long shaft-shaped shaft main body 2 is formed along the axial direction from the center portion of the outer end surface fitted into the inside of the portion 15a to the inner end surface that abuts the vertical surface of the numbered lateral recess. Yes.

Further, as shown in FIG. 3, for example, the horizontal shaft portion 15b of the inner handle 15 is continuous with the small-diameter portion 17 having the outer end surface, the step-like large-diameter portion 18 continuing to the small-diameter portion, and the step-like large-diameter portion. And a step-shaped small diameter portion 19 having the inner end face. The horizontal shaft portion 15b includes a short cylindrical first bearing plate 21 having a flange portion 21a, and a large-diameter portion of the step-shaped small diameter portion 19 which is located outside the short cylindrical first bearing plate 21. While being externally fitted to 19a, both are supported by a short cylindrical second bearing plate 22 having a flange 22a at the outer end portion with a predetermined interval. In the embodiment, the short cylindrical first bearing plate 21 has an inner end portion of the inner seat 11 that is fitted into the mounting hole 3 of the inner wall surface 1 a so as to press the first sealing material 10 against the inner wall surface 1 a of the door 1. Are fixedly arranged in a state supported by the C-shaped stopper 23. On the other hand, the short cylindrical second bearing plate 22 supports the short cylindrical outer end surface of the outer seat 12 fixed to the short cylindrical first bearing plate 21 via the fixing tool 13 by the flange 22a. The large diameter portion 19a of the stepped small diameter portion 19 is externally fitted. In addition, as shown in FIG. 3, the decoration cylinder 14 embodiment is formed in a cap-like having a female screw portion of the non-turn in the center, is screwed to the male screw portion 12a of the outer seat 12. Of course, the decorative cylinder 14 may have an engaging structure having a plurality of engaging claws at the peripheral end instead of a screwed structure.

    Therefore, with reference to FIG. 4, the first sealing material 10, the inner receiving seat 11, the outer receiving seat 12, and the like described above, together with the second sealing material (annular plate type oil seal) 50, which is a feature of the present invention, will be described. To do.

    First, the virtual line on the right side of the drawing is the inner wall surface 1a of the door. A water-stopping elastic body made of rubber or a similar annular plate as the first sealing member 10 is attached to the inner wall surface 1a. As shown in FIG. 5, the annular plate water-stop elastic body 10 has a fitting hole 10a into which the cylindrical part 11b of the inner seat 11 is fitted at the center, and a plurality of concentric circles of the fitting hole 10a. Through-holes 10b and 10b for the fixing tool 13. The shape, size, thickness, and the like of the waterstop elastic body 10 are matters that can be arbitrarily changed in design, but in the embodiment, as shown in FIG. 1, a cap continuous to the cylindrical portion 11 b of the inner receiving seat 11. It is formed in a shape / thickness that is substantially contained in a laterally-oriented annular recess 25 formed inside the cylindrical flange portion 11a.

    Accordingly, when the fixing member 13 is tightened, the annular plate water-stopping elastic body 10 is pressed against the inner surface of the cap-shaped flange portion 11a of the inner seat 11 in a surface contact state, so that the vertical inner side surface is against the inner wall surface 1a. It becomes a pressure contact state. Further, the inner diameter of the fitting hole 10 a of the annular plate water-stopping elastic body 10 is set so as to be in close contact with the outer peripheral surface of the cylindrical portion 11 b of the inner receiving seat 11. Therefore, it is possible to reliably prevent water and gas from entering the mounting hole 3 from the inner wall surface 1a of the door 1.

    Next, the configuration of the inner receiving seat 11 will be described. Reference numeral 11a denotes a cap-shaped flange portion having a plurality of through-holes 26, 26 for the fixing tool 13 that coincide with the through-holes 10b of the annular plate water-stopping elastic body 10 described above at appropriate places. Is provided with a cylindrical portion 11b having a predetermined length in the axial direction. The cap-shaped flange portion 11a has a function of pressing the inner wall surface 1a so as to wrap the annular plate waterstop elastic body 10 as described above, while the tubular portion 11b accommodates at least the second sealing material 50. It fulfills the function of the storage space 27.

    Next, an annular plate type oil seal 50 corresponding to the second sealing material will be described with reference to FIGS. The annular plate-type oil seal 50 allows water and gas to flow from the outer peripheral surface of the horizontal shaft portion 15b (the shaft main body 2 in some embodiments) of the inner handle 15 to the outer seat plate member (one mounting seat) 7 side through the mounting hole 3. In order to prevent intrusion, it is fitted into the storage space 27 described above.

    Therefore, the annular plate type oil seal 50 is held by the first form holding member 51 formed in the shape of an annular cap using a hard synthetic resin material or a rigid metal material, and the first form holding member 51. And an annular fitting portion 52 fitted in close contact with the inner peripheral surface 27a of the storage space 27, and an outer portion that is continuous with the annular fitting portion 52 and contacts the outer peripheral surface of the horizontal shaft portion 15b of the inner handle 15. An elastic annular seal lip portion 53 having inner lip portions 53a and 53b, and an inner side between the outer lip portion 53a and the inner lip portion 53b (the side facing the outer peripheral surface of the horizontal shaft portion 15b). An annular recess 54, an oil (grease) 55 filled in the annular recess 54, and the annular seal lip portion 53 are provided between the annular seal lip portion 53 and the annular fitting portion 52. Comprising a second embodiment holding member 56 of the elastic holding. In the embodiment, the protruding tip portion 52a of the annular fitting portion 52 is supported by the flange portion 21a of the short cylindrical first bearing plate 21 described above.

Alternatively, an inner annular wall 62 that has a slight gap and is closely fitted to the stepped small diameter portion 19 of the horizontal shaft portion 15 b of the inner handle 15, and between the inner annular wall 62 and the outer annular wall 61. The annular vertical wall 60 projects in an annular shape on the inner surface of the annular vertical wall 60 and projects from the annular fitting portion 52. Consisting intermediate annular wall 63 which contacts closely state Jo tip 52a.

In the second embodiment, oil (grease) 55 may be put in either the annular recess 54 or the oil reservoir 57, or the oil (grease) 55 may be put in both the annular recess 54 and the oil reservoir 57. Also good. When oil (grease) 55 is put in the oil reservoir 57, the oil (grease) 55 is placed on the outer surface of the inclined peripheral end portion of the second form holding member 56 of the annular seal lip portion 53 and the shaft of the inner annular wall 62. Water or the like enters the internal space of the door 1 by oil (grease) 55a that passes between the inner peripheral end portions extending in the direction and reaches the outer peripheral surface of the stepped small diameter portion 19 of the horizontal shaft portion 15b. Can be prevented. In the second embodiment, the outer stopper 24 does not exist as in the first embodiment. Instead of the inner and outer fasteners, the annular plate type oil seal 50 is sandwiched directly between the outer seat 12 and the lateral annular recess plate 58.
