Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、回転体を軸に固定する止めネジ等として用
いる段付きネジの改良に関する。TECHNICAL FIELD The present invention relates to an improvement of a stepped screw used as a set screw or the like for fixing a rotating body to a shaft.
〔従来の技術〕 止めネジにはワッシャーや皿バネ等がつきものである
が、止め作業の際にこれらを介在させることを忘れるこ
とがある。そこで、予めワッシャーや皿バネをネジ頭部
下にセットして容易に抜け出ないようにしておけば、そ
の締め付ければ付け忘れを防止できる。[Prior Art] Although a set screw has a washer, a disc spring, and the like, it is sometimes forgotten to intervene these during the fastening work. Therefore, if a washer or disc spring is set under the head of the screw in advance so that it cannot be easily pulled out, it is possible to prevent forgetting to attach it by tightening it.

た。このようにすると、ネジ部（11）のネジ山が皿バネ
（13）の内径よりも外側に突出し、このネジ部（11）が
皿バネ（13）等の抜け出し係止部として作用する。By the way, with a normal screw, as shown in FIGS. 4 and 5, before forming the screw part (11), the disc spring (13) and / or the washer are fitted under the screw head (12), and then, The screw part (11) was formed by knurling. In this case, the screw thread of the screw portion (11) protrudes outside the inner diameter of the disc spring (13), and the screw portion (11) acts as a slip-out locking portion of the disc spring (13) and the like.
このように通常のネジではネジ部（11）を作成する際

用も有効に活用できる。According to the present invention, even with a stepped screw, the locking protrusion can be easily formed on the stepped portion, thereby preventing the disc spring or washer from coming off, and forgetting to attach the disc spring or the like to the stepped screw. You can definitely lose it,
The tightening is made evenly and securely at each part, and the spring action of the disc spring etc. can be effectively utilized.
以下、図面について本発明の実施例を詳細に説明す
る。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

きくなるようにした。FIG. 1 is a partially cutaway front view showing an embodiment of a stepped screw of the present invention, and FIG. 2 is a partially cutaway front view showing the same manufacturing process as above, in which (1) is a stepped screw, 2) shows a disc spring. The disc spring (2) is attached to the step portion (3) of the stepped screw (1).
And the locking projections (4) are formed at appropriate intervals on the peripheral surface of the stepped portion (3) therebelow with a predetermined distance from the tightening surface at the tip of the stepped portion (3). As a result, a straight portion (3 ') is formed near the tip of the stepped portion (3) as a portion where the locking protrusion (4) is not formed. The protrusion degree of the locking protrusion (4) was made larger than the inner diameter of the disc spring (2).

このようにして、係止突起（４）があるので皿バネ
（２）は段付きネジ（１）に抜け出ずにセットされる。Then, as shown in FIG. 2, the locking protrusion (4) is fitted with a disc spring (2) on a ready-made stepped screw (1),
The knurling (5) is applied to the peripheral surface of the stepped portion (3) to form the knurling. In this case, by forming the straight portion (3 '), it is possible to prevent the displacement or deformation during processing from affecting the tightening surface of the stepped portion (3).
In this way, the disc spring (2) is set in the stepped screw (1) without slipping out because of the locking projection (4).

る。Next, an example of use of the stepped screw (1) having the disc spring (2) set therein will be described. As shown in FIG. 3, the rotating member (6) has a shaft (7) with a serration shaft structure.
In the case of fitting, the boss portion of the rotary member (6) is not penetrated but stopped midway, and a through hole (8) is provided in the upper closed portion.

け面が軸（７）の端面と密着するのみでネジ部（９）は
いっさいボス部には触れないようにした。On the other hand, at the center position of the shaft (7), there is formed a screw hole into which the tip of the set screw is to be inserted inward from the end, and the stepped screw (1) as the set screw is attached to the shaft (7). Insert from the side opposite to the insertion direction, and screw the tip screw part (9) onto the shaft (7). At that time, the step (3) of the screw (1)
Pierces the closed portion of the boss portion of the rotating member (6) (in this case, there is a slight gap between the step portion (3) and the through hole (8)), and the step portion (3 ) The tightening surface of the tip of Fig. 4) only comes into close contact with the end surface of the shaft (7), and the screw portion (9) is prevented from touching any boss portion.

がゆるんでしまうことはない。By doing so, the distance between the tightening surface of the stepped portion (3) and the disc spring (2) can be kept constant, and the torque of the shaft (7) is transmitted to the rotating member (6) via the serration shaft structure. Since the rotary member (6) and the stepped screw (1) are in slight line contact with each other via the disc spring (2), the rotary screw (6) is in contact with the stepped screw (1) from the shaft (7). Or torque from the rotating member (6) is transmitted and as a result the screw (1)
Does not loosen.

（３）の周面に適宜間隔に配列するようにしてもよい。Although illustration is omitted as another embodiment of the stepped screw (1), dot-shaped projections are arranged on the peripheral surface of the stepped portion (3) at appropriate intervals as locking projections of the disc spring (2). May be.
以上述べたように、本願発明は、係止突起を形成する

ジの弛みを防止できるものである。As described above, according to the invention of the present application, a deviation or deformation during processing when forming the locking projection can be absorbed by the straight portion, and it is possible to prevent the tightening surface from being affected. The tightening surface of the tip of the part completely and surely adheres to the tip of the shaft (7) which is the surface of the work, and the distance from the back surface of the washer to the tightening surface can be kept constant. It is possible to surely make line contact with each other, prevent the torque from the shaft (7) and the rotating member (6) from being transmitted to the screw, and prevent loosening of the screw.
