動用Ｖベルトに関する。[Detailed Description of the Invention] A. Purpose of the Invention (1) Field of Industrial Use The present invention relates to an endless belt-shaped strap, a plurality of pushing pieces supported along the strap, and the strap of the pushing piece. An endless belt retainer for preventing the retainer from falling out of the push piece, and a generally U-shaped strap arranging groove for accommodating the strap at the bottom of the pushing piece and a retainer engaging groove for engaging both side edges of the retainer. The present invention relates to a transmission V-belt formed.
（２）従来の技術 かかる伝動用Ｖベルトは、本出願人による特願平１−13
3341号において既に提案されている。(2) Prior Art Such a transmission V-belt is disclosed in Japanese Patent Application No. 1-13 of the present applicant.
Already proposed in 3341.

上極めて困難であり、このためにリテーナ係止溝の溝幅
はリテーナの厚さに比べてかなり幅広にならざるを得な
いのが実情である。(3) Problems to be Solved by the Invention By the way, the retainer locking groove formed in the pushing piece of the transmission V-belt has a groove width approximately equal to the thickness of the retainer engaging with the locking groove. However, it is extremely difficult in machining to form a groove with a width almost equal to that of a retainer made of a thin endless belt made of metal in the strap placement groove of the pushing piece, and therefore the groove width of the retainer locking groove is The reality is that the retainer must be much wider than it is thick.

大きく取ると、ストラップが横方向に位置ずれした際
に、そのストラップを構成する無端ベルトの側縁部がリ
テーナ係止溝に嵌合して傷付く虞れがある。However, since the strap held by the retainer is configured by stacking a large number of thin endless belts, if the groove width of the retainer locking groove is increased to facilitate processing, the strap is displaced laterally. At this time, there is a possibility that the side edge portion of the endless belt forming the strap fits into the retainer locking groove and is damaged.

ることは困難である。In order to avoid such an inconvenience, as disclosed in Japanese Patent Publication No. 57-23820, the saddle surface of the pushing piece against which the endless belt of the innermost layer of the strap abuts is centered by causing the saddle surface to protrude in an arc shape by crowning. However, even in this case, it is difficult to reliably center the endless belt of the outermost layer of the strap, which is difficult to achieve the crowning effect, to prevent the endless belt from being fitted into the retainer locking groove.

ラップ７に装着し、以下第１押し駒８と第２押し駒９を
交互にストラップ７に装着する。In order to assemble the endless belt 1, the retainer 10 is superposed on the outside of the strap 7, and an external force is applied to a part of the retainer 10 so that the retainer 10 is curved outward like a rain gutter (see a chain line in FIG. 6). Next, using the narrowed curved portion of the retainer 10, for example, after fitting the first pushing piece 8 to the position where the strap 7 abuts on the bottom of the strap placement groove 12, 1 The pushing piece 8 is slid along the strap 7. As a result, both side edges of the non-curved portion of the retainer 10 engage with the retainer locking groove 13 of the first pushing piece 8 to prevent the first pushing piece 8 from falling off. Next, the second pushing piece 9 is attached to the strap 7 via the curved portion of the retainer 10 in the same manner as described above, and thereafter, the first pushing piece 8 and the second pushing piece 9 are alternately attached to the strap 7.

干渉が防止される。In the V-belt 6 assembled in this way, the protrusions 16 and 16 and the recesses 17 and 17 of the first pushing piece 8 and the second pushing piece 9 are fitted,
In addition, due to the tension acting on the strap 7, both pushing pieces 8, 9
Are in close contact with each other. Then, by alternately mounting the first pushing piece 8 and the second pushing piece 9, as shown in FIG. 6, the retainer 10 is fitted with the retainer locking grooves 13, 13 of the first pushing piece 8 and the second pushing piece 8. Positioned in the vertical direction by the common overlapping portions of the retainer locking grooves 18, 18 of the piece 9, the retainer 7 is held by being sandwiched between the bottom surface of the strap disposing groove 12 of both push pieces 8, 9 and the lower surface of the retainer 10. . Thus, the power transmission from the drive pulley 3 to the driven pulley 5 by the V belt 6 is performed by the pivot line 14 of the first pushing piece 8 and the second pushing piece 9.
The upper parallel portions are in close contact with each other to transmit the pressing force. Then, the V-belt 6 drives the drive pulley 3
Alternatively, the two push pieces 8, 9 swing around the pivot line 14 when wound around the driven pulley 5, but at this time, the action of the inclined surface 15 formed on the lower side of the pivot line 14 causes the both push pieces 8, 9 to move. Interference is prevented.

される。Now, even if the endless belt constituting the strap 7 is displaced laterally for some reason, the retainer locking grooves 13, 13 of the first pushing piece 8 and the retainer locking groove of the second pushing piece 9 are displaced. Since the retainer 10 is engaged with the common overlapping portion of 18, 18 without a gap, it is possible to reliably prevent the endless belt of the strap 7 from being fitted into the retainer locking grooves 13, 13; To be done. In addition, the retainer locking groove 1 of the first pushing piece 8
Since the gap L 3 between the groove bottoms of the retainer locking grooves 18 and 18 of the second pressing piece 9 is formed larger than the gap L 2 between the groove bottoms of 3 and 13, the upper edge E of the common overlapping portion is formed. Has a substantially right-angled sharp shape, and as a result, the left and right side edges of the retainer 10 are prevented from riding on the edge E and being damaged.
