[Prior Art] The communication cable, the power supply winding, and the upper and lower water pipe are received. The locking device used for the entrance and exit cover of the same groove is exposed on the road due to the lock unit. Therefore, it is blocked by foreign matter such as mud, sand and sand discs; Therefore, the locking device for this purpose has a cap embedded in the remaining keyhole of the lock unit during most of the meat months. However, in the case of the common ditch operation, in order to open the lock unit, it is easy to invade the key hole by taking dust or sand, etc., and it is difficult to completely prevent this, for example, using a lock lock (an lnderlock) as the In the case of the lock unit of ^, there is a disadvantage that it is inferior or dysfunctional due to the intrusion of muddy water or sand. That is, since the lock cylinder lock is a wire-spring or a pin, it is easy to generate an enemy obstacle under the surface of the road. Li Yong and, as an example of a pin lock, are described in Japanese Patent No. 2002-147072. In addition, when the lock unit of the manhole door cover is malfunctioning, the handle of the key inserted into the key hole is rotated by a wrench or a pliers. In general, in the operation in the common ditch, the plurality of disc reels 13, 14, 15 are rotated in a situation other than the second 319182 5, and the pressing force is applied to the plurality of the following: The side stick (-Π, by receiving:::: the groove Uf of the groove and the slit 12b of the rotor 12 are located in the gap portion defined by the opposite groove 1 and the slit 12b, and may be l/^ The inside of the outer cover 11 is relatively rotated, and the lock plate and the rotor 12 are relatively rotated in the outer cover 11, and the predetermined portion of the hunting shovel 12 is abutted and pushed, and the front central shape is eight The hole (10), the sea lord "knows the opening Ub to cover; and the rear plate 20, and has a hole 2〇a', and the rear end opening lie' of the outer cover 11: the material of the front plate 19 is inserted into the hole i9a to the foregoing The rear plate a", "stop" is formed to communicate with an almost linear hole, and the = communication hole is formed to allow small stones, sand, and mud to be smaller than a predetermined particle size.

Then, the rotor 12 has a slit 12b' extending in the vehicle direction at a predetermined position of the tubular portion 12a, and a slit portion 12c extending in the axial direction is provided at a position opposed to the slit m. Since the notch portion is formed by a quarter-degree slit of the circumference of the tubular portion %, the cylindrical portion 12a is not so much a cylindrical body as it is actually two members having an arc-shaped cross section. Constitute. As shown in Fig. 6(b), a bottom plate 12e having a through hole l2d in the center is provided at the rear end of the tubular portion 12a, and an arcuate convex portion 12f is protruded from the surface side of the bottom plate. The rotor 12 described above is inserted into the outer casing 11 so as to be relatively rotatable with respect to the outer cover 11, but the slit 12b of the rotor 12 is disposed opposite to the outer cover uf groove Ilf, and the side stick 17 is housed by When the slit i2b / is defined by the groove, the relative rotation of the rotor 12 in the outer cover n is hindered, and the sub-window 17 is rotated from the groove 11 of the outer cover U in the row (four) of the material. In this part, as shown in Fig. 6 (8), the lock plate 18 is formed to be fitted with the pair of slit portions lie provided in the cover i to form the front end and the rear end (10), and the (four) ends 18a and rear, respectively. The inner side of the end 18b is formed with receiving portions 18c and 18d that abut against the arcuate convex portion of the rotor 12, and the intermediate portion of the front end and the rear end (10) is curved in such a manner as to cut the axis of the keyhole. The lock plate a, when the cover U is relatively rotated and the arc-shaped core 2 of the rotor 12 is connected to the receiving portion of the lock plate 18, the lock plate 18 is pushed toward the head A direction so that the front end 18a is larger than the outer cover ii The outer peripheral surface is more prominent, on the contrary 319182 1363129 Yin is almost 90. ) is the biggest one. Further, in the present embodiment, although three types of discs are exemplified = 15', the disc reels are not limited to three types, and a plurality of types of cymbals can be appropriately determined.
