considerably smaller than This point will be discussed later. A magnetic tumbler 4 is arranged concentrically in the diameter direction of the inner and outer cylinders 2 and 1 of the cylinder. A magnet 5 is embedded concentrically in the outer circumference of the key 3 with its tip exposed. 6 is the contact recess as described above, 7 and 8 are the tumbler holes of the inner cylinder 2 and outer cylinder 1, and K is the locking projection provided on the contact projection 3a of the key 3; Locks in the locking recess Ka when the inner cylinder rotates.

用することができる。(Description of the operation of the embodiment of the present invention) When the abutting convex portion 3a of the key 3 is fitted into the abutting recess 6 of the inner cylinder 2, as shown in FIGS. 1, 4, and 5. For example, the S pole of the magnet 5 is the N pole of the tumbler 4.
The pole is suctioned and the tumbler 4, which was straddling the shear line, is retracted into the inner cylinder 2. Contact convex portion 3a
That is, ideally, the diameter d of the abutment recess 6 is approximately equal to the circumference of the bottoms of the tumbler holes 7 of the inner cylinder 2, as shown in FIG. (See FIG. 4) By doing so, the exposed magnetic pole of the magnet 5 can act at a position closest to the magnetic pole of the tumbler 7.

（従来技術と本考案の目的）従来の磁石タンブラー錠をたとえばタイヤ盗難
防止用の錠前に用いたものは、タンブラーがシリ

あつた。本考案はこのような従来の磁石タンブラ
ー錠の問題点を解消するため、タンブラーをシリ
ンダーの直径方向に配設したものである。(Prior Art and Purpose of the Present Invention) In conventional magnetic tumbler locks used, for example, in locks for tire theft prevention, the tumbler is arranged in the axial direction of the cylinder, so the tumbler hole becomes long in the axial direction. . As a result, the cylinder became long, making it difficult to use it in a narrow space. In order to solve the problems of the conventional magnetic tumbler lock, the present invention provides a tumbler arranged in the diametrical direction of the cylinder.

（本考案の構成）タンブラーをシリンダーの直径方向に配設した
ので、シリンダーの長さが短かくなり、たとえば
タイヤ盗難防止用の錠として用いた場合、小型の
錠前を得ることができる。(Structure of the present invention) Since the tumbler is arranged in the diametrical direction of the cylinder, the length of the cylinder is shortened, and when used as a lock for preventing tire theft, for example, a compact lock can be obtained.

また磁力線の作用も強力である。 The effect of magnetic lines of force is also strong.

（本考案の作用効果）タンブラー４をシリンダーの直径方向に配設
したので、シリンダーの長さが短かくてすみ、
たとえばタイヤ盗難防止用の錠として用いれ
ば、小型となり、狭いスペースを有効に利用で
きる。(Effects of the present invention) Since the tumbler 4 is arranged in the diametrical direction of the cylinder, the length of the cylinder can be shortened.
For example, if it is used as a lock to prevent tire theft, it can be made small and make effective use of a narrow space.

磁石５の磁極をキー３の外周に露出して、タ
ンブラー４の磁極と吸引させる形式をとるた
め、接当凸部の直径ｄは内筒タンブラー孔７の
底部を連ねる円内にあるように設定する必要が
ある。この結果接当凸部３ａの直径ｄは内筒２
の直径Ｄよりはるかに小さいものとなり、キー
が小型になり、携帯に便利である。 Since the magnetic pole of the magnet 5 is exposed on the outer periphery of the key 3 and is attracted to the magnetic pole of the tumbler 4, the diameter d of the abutting convex portion is set to be within a circle connecting the bottoms of the inner cylinder tumbler hole 7. There is a need to. As a result, the diameter d of the contact convex portion 3a is the same as that of the inner cylinder 2.
It is much smaller than the diameter D of the key, making the key small and convenient to carry.
