等の軸方向の位置規制を行う事が出来る。 As shown in FIG. 4, the E-type retaining ring 100 is made by cutting out a part of a ring plate 101 made of metal or other elastic material by a predetermined angle range, and forming a notch opening 102 for insertion on the circumferential surface of the shaft. At the same time, a plurality of protrusions 103 are formed at appropriately angularly spaced positions on the inner circumferential side of the arc, and the retaining ring 100 is attached along the direction orthogonal to the shaft 1. By pushing into the slit groove 2, the retaining ring 1
00 inner circumferential side expands in diameter while causing elastic deformation with respect to the shaft 1, and returns to the original position at the slit groove 2 position. As a result, the protrusion 103 is engaged with and attached to the slit groove 2, and is attached to the shaft. Fitted pulley 104
It is possible to control the axial position such as

を行うものである。 On the other hand, a spring pin is formed of a thin metal tube with slits or serrations in the axial direction, and after setting its length to be larger than the shaft diameter, it is attached to the shaft peripheral surface along the direction perpendicular to the shaft. By press-fitting the pin into a drilled through hole and having both ends of the pin protrude from above the circumferential surface of the shaft, the position of the pulley fitted to the shaft is regulated.
しかしながら、かかるいずれの従来技術におい

なければならない為に、装着時に軸周面上で滑り
が生じ易く取付の際に専用治具を必要とする。 However, in any of these conventional techniques, since the stopper must be installed in a direction perpendicular to the shaft, slippage is likely to occur on the shaft circumferential surface during installation, and a special jig is required for installation.

なるという問題も派生する。 In addition, the fact that the stopper must be installed in a direction different from the mounting direction (axial direction) of the rotary body such as the pulley means that these members must be installed in two directions, which makes the installation work complicated. This also creates the problem that it becomes difficult to automate assembly work.

業が煩雑化する。 Now, rotary bodies such as the pulleys mentioned above are molded from resin materials in places where the load resistance is low or where low noise is required due to ease of molding. If there is a part whose diameter is expanded in a direction perpendicular to the molding direction, it is impossible to perform molding in one shot. In order to adopt a configuration in which multiple arbitrary points of the pulley are recessed along the radial direction perpendicular to the axis, the pulley, which has been molded with resin, must be cut to form the recessed portions and tongue pieces. , the processing work becomes complicated.

を立設させて形成した点にある。``Means for Solving Problems'' In order to solve such technical problems, the present invention consists of a pulley with flanges formed on both sides of the circumferential surface on which the belt is hung, and the shaft of the pulley is fitted into the pulley. A plurality of recesses are formed at arbitrary locations around the center hole along the radial direction orthogonal to the axis, and a tongue piece extending toward the center is formed in the recessed portion, and the tongue piece is inserted into the center hole. In a pulley shaft support mechanism configured such that the tongue piece is elastically deformed in the axial direction by a pressing force on the shaft side and can be engaged with a slit groove provided on the outer peripheral surface of the shaft, The first feature is that the flange located on one side is divided along the direction orthogonal to the axis, and a fitting recess and a fitting protrusion that can fit into each other are formed on the divided flange and the pulley body side. The second feature is that the recessed portion is formed so that the side of the divided collar portion facing the pulley body is open, and furthermore, a tongue piece is erected at the rear end of the recessed portion. It is at the point where it was formed.

に組付け可能に構成するのがよい。 In this case, on the divided flange side, a fitting protrusion having an inner circumferential surface formed along the diameter of the center hole is provided around the center hole sandwiching the recessed part, extending in the axial direction, and the fitting protrusion is inserted through the fitting protrusion. It is preferable that the pulley be configured so that it can be assembled integrally with a fitting recess provided on the pulley main body side.

である。 Further, as understood from the second feature, the recessed portion does not form a recessed portion by recessing the center hole, but is formed so as to open to the side facing the pulley body. In addition, since the tongue piece is also formed to stand up at the rear end of the recessed part, as a result, from the end face on the outer surface side of the divided collar part to the joint surface side on the pulley body side along the axial direction. It acts in the direction of uniformly reducing the diameter (increasing the diameter on the peripheral surface side of the center hole), and as a result, resin molding is possible in one shot.
即ち前記プーリ本体も鍔部側の分割体もいずれ
も鍔部より中央側に向けて軸線と直交する方向に
拡径される部位がない為に一発成形で容易に形成
出来る。 That is, since neither the pulley main body nor the divided body on the flange side has a portion whose diameter is expanded from the flange toward the center in a direction perpendicular to the axis, they can be easily formed in one shot.
又分割した鍔部をプーリ本体側に組付後は、前
記凹設部位はプーリ本体の接合面との間で断面
の字状に形成でき、問題が生じる事はない。 Furthermore, after the divided flange is assembled to the pulley body side, the recessed portion can be formed into a cross-sectional shape between the joint surface of the pulley body and no problem will occur.

た事を特徴とするプーリの軸支持機構。[Claims for Utility Model Registration] Consisting of a pulley with flanges formed on both sides of the circumferential surface on which the belt is hung, an arbitrary point around the center hole into which the shaft of the pulley is inserted can be positioned in a direction perpendicular to the axis. A plurality of recesses are provided along the direction, and a tongue piece extending toward the center is formed in the recessed portion, and the tongue piece is elastically deformed in the axial direction by the pressing force on the shaft side inserted into the center hole. At the same time, in a pulley shaft support mechanism configured to be able to engage with a slit groove provided on the outer circumferential surface of the shaft, the flange located on one side of the circumferential surface on which the belt is hung is moved along the direction perpendicular to the axis. A fitting recess and a fitting protrusion that can be fitted to each other are formed on the divided flange and the pulley body side respectively, and the recess is opened to the side of the divided flange facing the pulley body. What is claimed is: 1. A pulley shaft support mechanism, characterized in that a pulley shaft support mechanism is formed by forming a recessed portion and a tongue piece erected at the rear end of the recessed portion.
