The lock means 8 is formed by integrally forming an elastic biasing means 35x made of a zigzag elastic wall through a notch hole in the flat plate portion 9c. And a guide passage 45 facing the end of the elastic urging means 35x. On the other hand, an urging rib 46 that can enter the guide passage 45 is integrally formed on the flat plate wall 2 b of the first divided case 2. The elastic biasing means 35x and the biasing rib 46 constitute a part of the extraction lock mechanism.

  That is, as shown in FIG. 9A, when the lock means 8 is further inserted into the insertion path 7 of the case body 1 in the insertion direction F, the lock piece 19a, When 21a reaches the locking portions 19b and 21b, the arms 18a and 20a swing against the elasticity of the elastic hinge portions 18b and 20b. As shown in FIG. 9B, when the lock means 8 is further moved in the insertion direction F and the lock pieces 19a, 21a get over the locking portions 19b, 21b, the end of the urging rib 46 is guided by the guide passage. Entering from 45, the elastic biasing means 35x is elastically deformed in the compression direction. Therefore, when the force toward the insertion direction F is removed after the lock means 8 is completely inserted into the insertion path 7, the lock means 8 moves slightly in the extraction direction R due to the elastic force of the elastic biasing means 35x. Thereafter, the locking pieces 19a, 21a are locked to the locking portions 19b, 21b, thereby preventing movement in the sampling direction R. At this time, since the flange portion 42a of the lock piece 21a and the oblique edge 42b of the lock piece 19a are engaged with the engaging portions 21b and 19b, respectively, the magnets 43 and 43 are simply provided as in the case of the first embodiment described above. The arm 18a, 20a is configured not to swing in the unlocking direction only by facing. That is, when the operator pushes the lock means 8 and moves the lock means 8 in the insertion direction F against the elastic biasing means 35x, the locking of the collar portion 42a and the slanted edge 42b is released, and the arm 18a , 20a is swung toward the magnet of the unlocking group, and the lock means 8 can be removed from the case body 1.

  Moreover, 2nd Embodiment does not provide the locking piece like 1st Embodiment mentioned above. The auxiliary locking device is provided with the first lock piece 32 in the first divided case 2 and the second lock piece 33 in the second divided case 3, and when both the cases 2 and 3 are held together, the insertion direction of the lock means 8 With respect to F, the first lock piece 32 and the second lock piece 33 are configured to be arranged on the upstream side and the downstream side, respectively. In this respect, the same as in the first embodiment, A locking piece 34x integrally formed so as to extend long at the tip of the rod portion 9a is provided.

  Therefore, as shown in FIGS. 9A and 9B, when the lock means 8 is inserted into the insertion path 7 of the case body 1 in the insertion direction F, the lock piece 34x provided integrally with the lock means 8 is the first. The lock piece 32 is inserted into the second lock piece 33, thereby connecting the first lock piece 32 and the second lock piece 33 to each other. Thereby, the auxiliary | assistant locking mechanism which locks the case main body 1 so that it cannot open | release is comprised in the corner of the case main body 1 located on the opposite side to the insertion opening 6.
