  The engaging tool 59 released from the engaging pin 57 is in a state in which the stopper 62 is in contact with the upper end of the drop bar 51. Therefore, when the lock rod 51 is pulled out from the drop hole 54 and the lock is released, the operation knob 52 is gripped and raised along the holding frame 50. Then, since the connecting pin 67 is guided by the guide groove 65, the operation knob 52 and the drop bar 51 are lifted together while the engaging tool 59 is maintained in a predetermined posture, and the drop bar 51 comes out of the drop hole 54. .

  When the operation knob 52 is raised to the vicinity of the raised position, the engaging tool 59 rotates around the support shaft 58 against the spring 60. When the engaging portion 61 passes through the engaging pin 57, the engaging tool 59 is returned by the spring 60, and the engaging portion 61 engages with the engaging pin 57, whereby the drop bar 51, the operation knob. 52 can be held in the raised position.

  When the locking device 14 is assembled to the locking frame 15, first, as shown in FIG. 12, a decoration base 74 having a release lever 72 and a cylinder lock 73 is brought into contact with the side wall 28 of each divided body 26, Then, the decorative base 74 is fixed to the side wall 28 of each divided body 26 by inserting a screw 81. The handle 16 is similarly fixed to each divided body 26 with screws 88.

  Next, a case 75 is arranged between the two divided bodies 26, and both ends of the release shaft 77 and the locking shaft 78 are fitted to the release lever 72 and the plug 85 of the cylinder lock 73, respectively, so that the inner overlap of the two divided bodies 26 is achieved. The portion 30 and the outer overlapping portion 31 are superposed, and the case 75 is attached to the overlapping portion 30 of the side wall 35 of the locking frame 15 by a screw 80 inserted from the outside with a contact plate 79 applied to the outer side of the overlapping portion 30, 31. Fix to 31.

  In this way, by fixing the decorative bases 74 to the front and rear side walls 28 with the screws 81 from the closed space 27 side in the locking frame 15, the fixing screws 81 for the decorative base 74 are exposed to the outside. Can be prevented. Therefore, there is no possibility that the decorative base 74 is illegally removed by operating the screw 81 by a driver from the outside, and there is an advantage that the safety is further improved as compared with the conventional case.

  The locking frame 15 includes a divided body 26 that is divided into two in the front-rear direction, and a decorative base 74 is fixed to the side wall 28 of each divided body 26 including the front and rear side walls 28 of the locking frame 15. Although the decorative base 74 is fixed by the screw 81 from the closed space 27 side in the locking frame 15, the decorative base 74 can be easily fixed to the locking frame 15.

  The locking frame 15 includes a pair of divided bodies 26 having a substantially U-shaped cross section in which an inner overlapping portion 30 is bent at one end side in the width direction of the side wall 28 and an outer overlapping portion 31 is bent at the other end side. Since the inner overlapping portion 30 and the outer overlapping portion 31 of both divided bodies 26 are superposed and joined, the locking frame 15 can be configured using the divided body 26 having a simple shape.

  Further, a case 75 having a locking hook 71 and an operating mechanism 76 is fixed to the side wall 35 from the abutting plate 79 side by screws 80, and the locking frame 15 and the connecting frame 11 are fixed by fastening screws 44 of the fastening unit 36. The overlapping portions 30 and 31 on both the left and right sides of the locking frame 15 are fastened by screws 44, 48, 55, and 80 that are screwed into the overlapping portions 30 and 31 from the locking receiving frame 7 side. In the locked state, since the locking frame 15 and the locking receiving frame 7 are in contact with each other, there is no possibility that these screws 44, 48, 55, and 80 are illegally removed by an operation from the outside. For this reason, it can assemble easily, ensuring safety.

  Further, by using a fastening screw 44 for fixing the locking frame 15 and the connecting frame 11, a screw 48 for the cap 47, a screw 55 for the holding frame 50, and a screw 80 for the case 75, the two divided bodies 26 are overlapped.
