したシリンダケースカバーを示す。Prior Art As shown in Fig. 1, in automobiles, in order to lock and unlock the locking devices for opening/closing bodies such as trunk lids T/L and doors D from the outside of the vehicle, key cylinders are installed in these opening/closing bodies T/L, D. 1 is installed. Key cylinder 1 is installed. As shown in FIGS. 2 and 3, the key cylinder 1 is roughly composed of a cylinder case 2, a cylinder body 3 housed inside the cylinder case 2, and a key lever 4 fixed to the rear end of the cylinder body 3. . Cylinder body 3
A vertically elongated key plate insertion hole 5 is formed in the axial direction of the key plate insertion hole 5.
A plurality of tumblers 6 are provided, each of which is urged toward the center of the cylinder body 3 by a spring (not shown) from its longitudinal end portions 5a, 5a. This key cylinder 1 is inserted into the mounting hole H formed in the outer panel O/P of the opening/closing body T/L, D, and a retaining clip 7 is inserted between the locking protrusion 2a on the outer periphery of the cylinder case 2 and the back surface of the outer panel O/P. It is loaded with bullets and fixed to prevent it from coming out. Further, the key lever 4 has a lock 8 connected to a locking lever of a locking device (not shown) at its free end 4a,
The rotational movement of the cylinder body 3 is transmitted to the locking lever via the rod 8 to lock and unlock the locking device. In addition, 9 in FIG. 2 is the cylinder main body head 3a.
10 is a keyhole shutter, and 11 is a cylinder case cover fitted to the end of the cylinder case 2.

置が不正解錠されてしまう不具合があつた。 However, in such a conventional structure, the key plate insertion hole 5 is formed vertically to facilitate locking and unlocking operations using a key plate (not shown), and therefore, the key plate insertion hole 5 (not shown) is inserted into the key plate insertion hole 5 from the outside of the vehicle. When the correct unlocking means is inserted and the lock device is pried in the unlocking direction, for example in the direction of pulling the rod 8 upward, the outer panels O and P are deformed and the key cylinder 1 is tilted in the aforementioned unlocking direction. There was a problem where the lock device could be unlocked illegally.
発明の目的
本発明はかかる従来の実状に鑑み、キーシリン
ダが不正解錠手段によつてこじり倒されて、ロツ

を提供することを目的とするものである。Purpose of the Invention In view of the above-mentioned conventional situation, an object of the present invention is to provide a key cylinder in which the lock device will not be illegally unlocked due to the key cylinder being pried down by an unauthorized unlocking means. It is.

いようにしてある。Structure of the Invention In order to achieve the above-mentioned object, in the present invention, a slit is provided in the head of the cylinder body extending from the end in the length direction of the key plate insertion hole to the outer periphery of the head, and the key plate insertion hole is Even if an unauthorized unlocking means is inserted into the key cylinder and an attempt is made to force the key cylinder in the unlocking direction, the tip of the unauthorized unlocking means slips in the slit, and no external force in the tilting direction is applied to the key cylinder.
実施例
以下、本発明の実施例を図面と共に前記従来の
構成と同一部分に同一符号を付して詳述する。Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, with the same reference numerals assigned to the same parts as in the conventional structure.

頭部３ａ外周に至るスリツト１２を形成してあ
る。 That is, in the present invention, as shown in FIGS. 4 to 6, the head 3a of the cylinder body 3 is provided with a hole extending from the longitudinal end portions 5a, 5a of the vertically elongated key plate insertion hole 5 to the outer periphery of the head 3a. A slit 12 extending all the way is formed.

解錠を免がれることができる。 With the above configuration, even if an unauthorized unlocking means (not shown) is inserted into the key plate insertion hole 5 from the outside of the vehicle and an attempt is made to pry the key cylinder 1 down in the unlocking direction in which the rod 8 is pulled upward, the lock will not be locked. This makes it possible to avoid the tip of the correct locking means slipping within the slit 12 and causing what is called a missed swing, thereby preventing the key cylinder 1 from being twisted over. Moreover, even if the tip of the unauthorized unlocking means is tilted greatly until it hits the inner surface of the cylinder case 2, the tip of the unauthorized unlocking means may slide on the inner surface of the case 2. Since the gripping side is close to the outer panel O/P surface and cannot be tilted significantly, unauthorized unlocking can be avoided.

に対応することができる。 Further, as shown in FIG. 7, the slits 12, 12
If the cross-sectional shape of a is made into a wedge shape, even if the tip is pried by an unauthorized unlocking means having a wedge shape, there is no part to get caught, so it can be handled reliably.

その実用上の効果は多大である。Effects of the Invention As described above, according to the present invention, even if an attempt is made to pry the key cylinder in the unlocking direction by the unauthorized unlocking means, the unauthorized unlocking means can be swung in vain, thereby preventing the locking device from malfunctioning. It is possible to reliably prevent incorrectly unlocked locks, and therefore, although it has a simple structure, its practical effects are great.
