Although it is possible to operate as described above, the spindle 2 that supports the operating lever 25 of this latch device.
Since one end 26a side of 6 is supported by the shaft support portion 27 by the configuration shown in FIG. 6 to FIG. 8 described above, for example, in order for the carrier to lift the wagon 1, the hand is deeply inserted into the drawer handle recessed portion. Even when the operation lever 25 is strongly operated so as to be pushed backward while rotating in the direction opposite to the pulling operation, the first retaining step portion 26h of the support shaft 26 causes the shaft support portion 2 to move.
The first stop step portion 27f of No. 7 contacts the shaft support portion 27 of the support shaft 26 to prevent the support shaft 26 from falling off. Further, in this embodiment, even if the operation lever 25 is strongly pulled, the support shaft 26 does not come off from the shaft support portion 27. That is, from the operation position C (see the solid line in FIG. 8) in which the tip end portion 34 of the latch claw 34 is rotated to the innermost position and the drive arm 39 cannot be rotated further forward, the operation lever 25 is further moved.
When the tow is strongly pulled forward, the one end 26a side of the support shaft 26 is moved toward the other end 26 and the drive arm 39 by the reaction.
Although it tries to rotate backward with the tip of the shaft as a fulcrum, its backward movement is blocked by the second stopper step 26d hitting the second stop step 27e of the shaft support 27. Therefore, it is possible to reliably prevent the support shaft 26 from coming off the shaft support portion 27.

When the operating force is not applied to the operating lever 25, the drive arm 39 is prevented from rotating forward by the driven plate 46 of the latch claw 34, and the first retaining step portion 26h and the first retaining step portion 26h. Since the rearward rotation is also suppressed by the contact with or close proximity to the first stop step portion 27f, even if the drawer 3 is tilted or vibrated, the operation lever 25 does not hang and the appearance can be improved. Further, even if the operation lever is suddenly released from the pulling operation state or the like, the first retaining step 26h and the first stop step 27f
Since the rearward rotation is suppressed by abutting with the contact, it is possible to prevent a problem that a large metallic sound is generated due to the tip of the drive arm 39 hitting the upper plate of the drawer 3.
