  Next, when the door 2 is closed, the latch 15 having the convexly curved tip is brought into sliding contact with the projection 2b of the door frame. As a result, the coil spring 86 is compressed, and the latch 15 moves forward while retracting slightly in the transverse direction Z, and enters the latch receiving portion 2a and is locked. In the locked state, even if a third party who does not possess the key 33 attempts to slide by holding the control lever 16, the control lever 16 is not moved since it is locked by the restriction lock member 60. Further, since the first display unit 80a notifying locking is exposed in the window hole 27, the operator or the like can confirm that the locking device 10 is in the locked state.

  Referring to FIGS. 9A and 9B, when the resident who comes back home opens the storage box 1, the key 33 is inserted into the key hole 30a located in the front wall portion 21 and the locking plate 37 is upward R1. By rotating to pivot to move the regulating lock member 60 upward, the hook portion 67 is withdrawn from the protrusion receiving hole 55, and the regulating lock (locking) is released. Since the restriction lock member 60 is latched to the lid 12 via the engagement means 89 in a pulled up state, the resident approaches the operating lever 16 to the finger rest 17 in a state in which the key 33 is released. As a result of the sliding operation, the latch 15 can be withdrawn from the latch receiving portion 2a and the door 3 can be opened. After the resident takes out the package, by closing the door with the regulation lock member 60 being held upward, the delivery person returns to the state before locking.

  The locking device 10 according to the present embodiment does not require a power source as in the case of an electric lock or the like, so that it can be installed in the vicinity of the gate or entrance of a detached house. In addition, since the components accommodated in the case 20 are mainly composed of the latch member 40, the slide member 50, and the restriction lock member 60 without the need for electric parts, compared with the conventional lock device for the storage box It has a simple configuration and can be manufactured at low cost. Furthermore, unlike the conventional electric lock etc., there is no need for the delivery person to leave the PIN by memo paper etc., and the resident does not need to take time and effort to input the PIN according to the memo, and can be unlocked quickly. Although not shown, the seal of the resident is disposed in the housing 2 of the containing box 1 as a means for sealing the delivery slip in order to obtain proof that the delivery person has delivered the package in the absence of the resident. A placement table may be installed.

  In addition, the latch 15 and the slidable operation lever 16 are not formed from separate members, but are formed from an integral member, so that the latch 15 can be reliably engaged from the latch receiving portion 2a by the slide operation. You can leave it. Furthermore, by positioning the finger rest 17 projecting from the front wall 21 so as to line up with the control lever 16 in the transverse direction Z, for example, while operating the finger rest 17 with the index finger, the thumb operates the lever Since the slide movement of 16 is sufficient, the operation can be smoothly performed with one hand.
