率良く加工することができる。〈Function/Effect〉 In this way, a key with a complex three-dimensional shape, which has a claw at the tip and a protrusion protruding inside the inner hole, was made by machining such as cutting or pressing instead of casting. It is easy to manufacture and can be made into high-precision keys at low cost. In particular, the elongated hole provided in the key body can be formed easily and efficiently because the wall thickness can be reduced and the hole can be easily punched out using a press.
〈実施例〉 以下、本発明の実施例を図面に基づいて説明する。<Example> Embodiments of the present invention will be described below based on the drawings.
キーは把持部ｌとキー本体部２とから構成され、各々別

の半円孔１ｃが穿設される。The key is composed of a grip part l and a key body part 2, each of which is manufactured separately.The grip part 1, which is then connected and fixed, is made by punching out a steel plate by press working. It is processed into the shape shown in Figure J2. That is, at the tip of the plate-shaped grip 1, a protrusion 1a that is fitted into a slit in the key body 2 and projects into the inner hole of the key body 2, which will be described later, and a key tip claw 1b are integrally formed. Ru. Further, near the center of the grip part 1, a semicircular hole 1c is bored into which the round tip of the key body part 2 is inserted when it is caulked.
一方、キー本体部２は、円柱状の鋼材を、第１図に示す
ように順に機械加工して形成される。On the other hand, the key body part 2 is formed by sequentially machining a cylindrical steel material as shown in FIG.
即ち、先ず、丸棒の鋼材を旋盤などにかけ、先端を弾丸

厚を薄くするために形成される。Next, the semi-finished key body is put into a press machine, the flange part is dropped so as to leave the tip claw part 28 on one side of the end, and an axial slit 2b is formed in the rounded tip part by cutting. II in Figure 1) Next, a shallow edge 2c is formed on the side of the semi-finished key body by cutting ('s1
(■) in the figure, the groove 2C is formed on one side of the outer periphery on the extension line of the slit 2b, and is formed to reduce the thickness of that part of the key body 2.

レスで容易に打ち抜くことができる。Next, under the groove 2c formed in the above step, a long hole 2d into which the protrusion 1a is inserted is formed by press working (■ in Fig. 1). Since it is formed at the lower part of the thinned 2cm thick (for example, 1cm thick), it can be easily punched out with a press without inserting a female die into the inner hole of the semi-finished key body.

出する。Then, the grip part 1 and the key body part 2 formed in this way
As shown in FIG. 2, the protrusion 1a of the grip part 1 is inserted into the elongated hole 2d of the key body part 2, and the vicinity of the semicircular hole IC of the grip part 1 is inserted into the slit 2b of the key body part 2. In this state, the round tip portions of the key body portions 2 are caulked inward and inserted into the semicircular holes IC, thereby connecting and fixing them to each other. In this state, the tip claw portion 1b provided on the grip portion 1 protrudes from the tip of the key body portion 2, and the projection portion 1a protrudes into the inner hole of the key body portion 2.
そして、錠本体側のタンブラ−ピンと係合する凹部がキ

行った後、メツキ処理されキーが完成する。A recess that engages with a tumbler pin on the lock body side is provided on the outer periphery of the tip of the key body 2, thereby producing a key as shown in FIGS. 3 and 4. After that, the barrel is processed and then plated to complete the key.
このように、先端爪部１ｂ、２ａを有し、内孔内に突起

に効率良く加工することができる。In this way, a key having the tip claw portions 1b and 2a and the projection portion 1a protruding into the inner hole can be manufactured relatively easily by machining such as cutting or pressing instead of casting. It is possible to make high-precision keys at low cost. In particular, the elongated hole 2d provided in the key body portion 2 can be made thin and easily punched out with a press, so it can be easily and efficiently processed.
