の欠点があつた。 Conventionally, in cases such as those molded from thermoplastic synthetic resin, a locking piece with a wide claw protruding from the front frame is provided, and the rear frame faces and engages with this claw. The front frame and the rear frame are connected by forming a possible recess and locking a claw in the recess. However, because of this configuration, the wall thickness in the depth direction of the front frame portion where the locking piece is erected becomes thicker.
Sink marks appear on the front of the front frame after molding. This sink mark is more noticeable as the width of the locking piece in the left-right direction becomes wider, and it is more likely to occur as the locking piece becomes thicker in the depth direction, which is not aesthetically pleasing. Also, in order to make sink marks less noticeable, you can make the locking pieces narrower in the horizontal direction or thinner in the depth direction, but this method weakens the bonding strength between the front frame and the rear frame. There were drawbacks such as:
本考案は上記欠点を除去するもので、ひけが現

ことのないケースなどにおける結合構造を提供す
るものである。 The present invention eliminates the above-mentioned drawbacks and provides a joint structure for cases, etc., which does not cause sink marks and does not impair the strength of the joint between the front frame and the rear frame.

としての結合強度をさらに大きくできる。 Embodiments of the present invention will be described below based on the drawings. As shown in Figures 1 and 2, the front frame 1 is made of thermoplastic synthetic resin, and has locking pieces 3 erected on the inner circumference for locking the rear frame 2. There is. The locking piece 3 is attached to two support columns 4a and 4b that are erected at a predetermined interval from the inner bottom surface of the front frame 1 toward the rear frame 2 along the side wall, and to the upper ends of both support columns. It is constituted by claw portions 5 which are integrally arranged in a continuous manner. The support columns 4a, 4b are formed to have a narrow width a1 at the connection portion with the front frame 1 (in the surface direction of the front frame) and a large thickness a2 in the depth direction. The claw portion 5 is formed so as to be able to be engaged with a recess 6 formed in the rear frame 2. Therefore, since the width a1 of the portion where sink marks are likely to occur, which is formed thickly in the depth direction, is narrow, sink marks hardly appear on the front surface of the front frame. In addition, the claw portion 5 is formed by increasing the distance between the support columns 4a and 4b.
Since the width is sufficiently wide, the locking piece 3 has a sufficient degree of connection. . As shown by the chain line in FIG. 2, by additionally erecting a third support column 4c between the support columns 4a and 4b, the connection between the claws 5 can be strengthened, and the connection strength as an engagement piece can be further increased. can.
なお本考案は上例に限らず、第４，５図示のよ
うに係止片１３の支持柱１４を半円形状に形形し
て支持柱が爪部１５の背部において連結した構造
にすれば、係止片としての結合強度を大きくでき

角形状にして爪部２５の背部で連結した例であ
る。連結した支持柱は上記形状に限られない。 Note that the present invention is not limited to the above example, but the support column 14 of the locking piece 13 may be formed into a semicircular shape and the support column may be connected at the back of the claw portion 15 as shown in the fourth and fifth figures. , the bonding strength as a locking piece can be increased. The locking piece 23 shown in the sixth and seventh figures is an example in which the support column 24 is formed into a triangular shape and connected at the back of the claw portion 25. The connected support columns are not limited to the above shape.
以上説明したように本考案によれば、前枠前面
