In this way, the auxiliary lock 10 (the digging pull 10A) can be easily and highly attached to the frame 18 having the resin frame 24. In addition, since no screw or the like is required for fixing the auxiliary lock 10 (digging handle 10A), the cost is low and the appearance quality is excellent.

  Incidentally, the auxiliary lock 10 (digging handle 10A) has a clearance C along the longitudinal direction of the lower frame 18b (door frame 18c) between the mounting hole 32 (52) and the main body 38 (56). (See FIGS. 5B and 8B). The resin frame member 24 may generate a large thermal expansion in the longitudinal direction due to the influence of the outside air temperature or the like. In this regard, the auxiliary lock 10 (digging handle 10A) is inserted into the mounting hole 32 (52) of the resin frame member 24 via the clearance C. For this reason, even when the resin frame member 24 is thermally elongated in the longitudinal direction, this thermal expansion can be absorbed by the clearance C, and the auxiliary lock 10 (the digging pull 10A) is not affected.

  On the other hand, since such a clearance C is provided, there is a concern that the auxiliary lock 10 (digging handle 10A) may rattle in the longitudinal direction of the lower frame 18b (door frame 18c). In this regard, the auxiliary lock 10 (the digging pull 10A) is positioned by engaging the engaging portion 38b with the positioning hole 34 (54) of the metal frame member 22. For this reason, the occurrence of rattling of the auxiliary lock 10 (digging handle 10A) is suppressed. In addition, the auxiliary lock 10 (digging handle 10A) has a press-fit projection 38e that generates frictional resistance between the auxiliary lock 10 and the mounting hole 32 (52). For this reason, the occurrence of rattling of the auxiliary lock 10 (digging handle 10A) is further suppressed.

  The mounting hole 32 (positioning hole 34) has a projecting hole 32a on the side of the lower frame 18b connected to the mating frame 18d. As a result, in the lower frame 18b, the mounting holes 32 (positioning holes 34) do not become wider on the side of the connection end with the assembling frame 18d, and a reduction in strength thereof is avoided.

  It should be noted that the present invention is not limited to the above-described embodiment, and may be freely changed without departing from the gist of the present invention.

  The metal material forming the positioning holes 34 (54) may be other than the metal frame material 22 connected to the resin frame material 24. For example, as shown in FIG. 10, the frame 18 may be formed of only the resin frame 24 without the metal frame, and the hollow portion 26 may be formed. In such a configuration, a reinforcing material 60 such as steel or stainless steel may be inserted into a hollow portion or the like provided on the outside of the inner resin frame member 24. Therefore, in this case, the positioning hole 34 (54) may be formed in the finding wall portion 60a of the reinforcing member 60, and the auxiliary lock 10 (digging handle 10A) may be attached and fixed thereto.

  In the above, the configuration in which the engaging portion 38b has the engaging concave portion 38c and the engaged convex portion 34b is provided at the edge of the positioning hole 34 (54) has been exemplified. However, the configuration may be such that the engaging portion 38b has an engaging convex portion, and an engaged concave portion is provided at the edge of the positioning hole 34 (54).

  In the above description, the positioning hole 34 has the same shape as the mounting hole 32, but both may have different shapes. However, if the positioning hole 34 and the mounting hole 32 have the same shape, both can be formed at once, resulting in low cost and high manufacturing efficiency.
