向溝８ｂの他方の端面は押止め部１３としている。The notch 8 is composed of an axial groove 8a that extends in the axial direction and has one end open to the end face, and a circumferential groove 8b that extends circumferentially from the bottom of the axial groove 8a. Both grooves 8a and 8b are provided. Thus, a bent piece 9 that can be bent outward in the radial direction is formed on the remaining portion. An end surface of the bent piece 9 on the circumferential groove 8b side is provided with a slope to form a retaining portion 10, and an end surface on the axial groove 8a side serves as a first rotation stopping portion 11, and the axial groove 8 is formed.
The other end surface of a is the second rotation stopping portion 12, and the other end surface of the circumferential groove 8b is the pressing portion 13.

ッパ面１８を有している。Reference numeral 14 shown in FIGS. 1 to 4 and the like is a frame. As shown individually in FIGS. 7 and 8, a receiving hole 15 penetrating the front and back surfaces thereof is provided and associated with the receiving hole 15. Thus, a stopper 16 protruding outward and a protrusion 17 protruding radially inward of the receiving hole 15 are formed on the front surface side. The protrusion 17 has such a shape and size that it can fit in the axial groove 8a of the notch 8, and the stopper 16
Has a stopper surface 18 having a shape corresponding to the movement trajectory of the first rotation stopping portion 11 when the bending piece 9 is bent outward in the fitted state.

And widths t 1 and t 2 of the circumferential groove 8a (t 1 <t 2 , t 1 : back side, t 2 :
The dimensional relationship with the (inlet side) is set so that t 1 <s <t 2 . Therefore, when the pipe shaft 7 is inserted into the receiving hole 15, the end portion of the pipe shaft 7 is inserted into the frame 1
The length protruding from the outer surface of 4 corresponds approximately to the width dimension of the bent piece 9.
次に、作用について説明する。Next, the operation will be described.

ト７の端部を外側に突出させる。1 to 3 show the pipe shaft 7 with the receiving hole 1 of the frame 14.
FIG. 5 is a view showing a state where the pipe shaft 7 is penetrated through, and the pipe shaft 7 is inserted into the receiving hole 15 from the inside of the frame 14, and the cutout 8 is formed.
The projection 17 is inserted into the axial groove 8a of the above so that the end portion of the pipe shaft 7 is projected outward.
次に、第４図に示すように、折曲片９を半径方向外側に

止部１１をストッパ面１８に係止することができる。Next, as shown in FIG. 4, the bent piece 9 is bent outward in the radial direction, the retaining portion 10 thereof is engaged with the edge of the receiving hole 15, and the first rotation stopping portion 11 set at the tip end. Is brought into contact with the stopper surface 18 of the stopper 16. In this case, since the stopper surface 18 has a curved surface shape that matches the rotational displacement of the bending piece 9, the bending piece 9 can be bent along the stopper surface 18, and the tip of the bending piece 9 can be bent at an appropriate position. The first rotation stopping portion 11 can be locked to the stopper surface 18.
このように、折曲片９を外側に折り曲げて受穴１５の縁

る。In this way, by merely bending the bent piece 9 outward and engaging the edge of the receiving hole 15, the pipe shaft 7 moves in the axial direction (pushing direction X and pulling direction Y) and in the circumferential direction (clockwise direction Z). And counterclockwise W) to prevent the frame 14
It is possible to support and fix the pipe shaft 7.

の回転が阻止される。That is, as shown in FIG. 4 and the like, the pressing portion 13 of the axial groove 8 a of the cutout 8 provided in the pipe shaft 7 is provided with the receiving hole 15.
Since the protrusion 17 of the frame 14 that projects inward abuts from the inside, the movement of the pipe shaft 7 in the pushing direction X is prevented, and the retaining portion 1 of the bent piece 9 is prevented.
Since 0 is engaged with the peripheral edge of the receiving hole 15 of the frame 14, this prevents the pipe shaft 7 from moving in the drawing direction Y. At the same time, the pipe shaft 7
The second rotation stopper 12 of the axial groove 8a of the notch 8 provided in the
Is abutted on the side surface of the protrusion 17, which prevents the pipe shaft 7 from rotating in the clockwise direction Z, and the first rotation stopper 11 provided at the tip of the bent piece 9 causes the frame 14 to rotate.
Since it abuts against the stopper surface 18 of the stopper 16 provided on the above, rotation of the pipe shaft 7 in the counterclockwise direction W is prevented thereby.
その結果、パイプシャフト７がフレーム１４に対して回

ト７をフレーム１４に固定支持することができる。As a result, the pipe shaft 7 is supported so that it cannot rotate with respect to the frame 14 and cannot move in the axial direction. Therefore, the pipe shaft 7 can be fixedly supported on the frame 14 only by the pipe shaft 7 without requiring fixing parts such as nuts and washers as in the conventional case.
第９図乃至第１１図には、本考案の第２の実施例を示

パ１６は不要となる。他の構成は、前記実施例と同様で
ある。In this case, the bottom surface of the recessed portion 20 forms the pressing portion 13, and the end surfaces on both sides form the first rotation stopping portion 11 and the second rotation stopping portion 12. Therefore, the stopper 16 in the above embodiment is unnecessary. The other structure is the same as that of the above embodiment.
本実施例の作用は、次の通りである。The operation of this embodiment is as follows.
パイプシャフト７の端部をフレーム１４の受穴１５に貫
通し、凹欠部２０に突起１７を挿入して当該端部をフレ
ーム１４の外面から突出させ、しかる後、折曲片９を外
側へ折り曲げる。The end of the pipe shaft 7 is passed through the receiving hole 15 of the frame 14 and the protrusion 17 is inserted into the recess 20 to project the end from the outer surface of the frame 14. After that, the bending piece 9 is moved outward. Fold.
これにより、パイプシャフト７がフレーム１４に固定支

れる。In this case, the pressing portion 13, which is the bottom surface of the recessed portion 20, comes into contact with the inner surface of the protrusion 17, which prevents the pipe shaft 7 from moving in the pushing direction X in the axial direction. At the same time, the first rotation stop portion 11, which is one side end surface of the recessed portion 20, abuts on one side surface of the protrusion 17, which prevents rotation of the pipe shaft 7 in the counterclockwise direction W. Further, the second rotation stopping portion 12, which is the other side end surface of the recessed portion 20, comes into contact with the other side surface of the protrusion 17, whereby rotation of the pipe shaft 7 in the clockwise direction Z is prevented.
さらに、第１２図には、本考案の第３の実施例を示す。Furthermore, FIG. 12 shows a third embodiment of the present invention.
