することにある。In the above, since the upper side of the driver is covered with the connecting member, a space occupied by the covering portion of the connecting member is required above the driver, and the height to the upper end surface of the connecting member is required. It has the drawback of being expensive. Then, the drive member is fitted into the drive member accommodating portion of the U-shaped connecting member so as to overlap in the height direction, and the wall of the connection member (covering the wall of the connection member is provided on the upper side in the height direction of the drive member. If there is no portion), if the strength of the connecting member can be secured, then the thickness of the connecting member can be made thin, and the overall height can be increased as described above by just projecting within the height of the drive member or slightly above the height. Although the problem can be solved, the mounting direction of the connecting member with respect to the slide member is fixed, and the mounting of the connecting member cannot be performed unless the mounting direction of the connecting member is a predetermined direction. If the slide unit is configured as a whole as in, this may not be a problem because the connecting member is assembled at the manufacturing plant, but the rodless cylinder and the connecting member may not be connected. This is not preferable because it requires some caution for a user who wants to assemble a single product and incorporate it into an industrial machine designed by himself. However, there is a drawback that the height from the rodless cylinder to the slide member becomes high similarly to the fact that the number of parts is large, it takes time to assemble, and the mounting bolt projects above the bracket. As mentioned above, for users who incorporate rodless cylinders into their own designed machines,
A large number of parts is not preferable because the number of assembling steps increases. In view of these conventional techniques, the problem of the present application is to
An object of the present invention is to provide a connecting mechanism that connects a drive member of a drive mechanism and a slide member very easily and without paying attention to the mounting direction, and that can suppress the height thereof to a low level.

The connecting member is a single member having a pair of locking surfaces facing each other, and is locked in the moving direction with the locking surface before and after the moving direction of the drive member, and in the direction orthogonal to the direction. A guide surface that allows movement is provided, and the connecting member has front and rear walls on which a pair of locking surfaces are formed, which are connected by a connecting wall located outside in the width direction of the driving member.
In a connecting mechanism that is formed with open drive member accommodating spaces on both sides in the thickness direction of the connecting member, the connecting member has a uniform thickness.
The front and rear walls are located on both outer sides in the width direction of the drive member.
Connected with the connecting wall located, the drive member accommodation space is an annular hole
The upper and lower surfaces in the thickness direction are formed on the connecting surfaces with the slide member, respectively, and the mounting screw holes are penetrated in the thickness direction.
It is characterized by being provided through (claim 1). Specifically, the drive member is a piston of the outer moving body of the rodless cylinder.
Ton mount and connect the annular hole of the connecting member to the piston mount.
The connection member in the thickness direction.
Almost all of them overlap the outer moving body (claim 2). In this configuration, since there is no wall of the connecting member on the upper side in the height direction of the driving member, the thickness of the connecting member is reduced to be substantially the same as the surface in the thickness direction of the driving member or the surface in the thickness direction of the driving member. Since it can be projected slightly, the overall thickness can be reduced, and since both sides in the thickness direction of the connecting member are connecting surfaces, it can be installed without worrying about the mounting direction of the connecting member Since the member is a single member, the structure is simple and easy to handle, and there is no need for assembly. It is preferable that the connecting member is made of an extruded mold material because the cost can be reduced (claim 3) .

材１０２を固着することになる。When the slide member 101 and the piston mount 23 of the rodless cylinder 1 are connected via the connecting member 102, the connecting member 102 is made of a single member, and both sides in the thickness direction of the connecting member 102 are the sliding member 101. Connection surfaces 107, 107 of the mounting screw hole 10
Since 8 penetrates, it can be fixed to the slide member 101 with the mounting screw 109 without distinguishing the front and back, and the handling is extremely simple. Although the piston mount 23 is fitted in the drive member accommodating space 104 of the connecting member 102, the locking surfaces 105, 105 of the connecting member 102 are axially engaged with the guide surfaces 106, 106 of the piston mount 23. , Because it can move freely in the direction orthogonal to it,
Even if the piston mount 23 of the rodless cylinder 1 and the slide member 101 are slightly displaced from each other in the vertical and horizontal directions, when the slide member 101 is transferred by the piston mount 23, the movement is caused by the above-mentioned movement. Since the deviation (error due to assembly) is absorbed and the slide member 101 is reliably guided along the guide rail 100, it is not necessary to assemble each other with high precision, and the assembly work can be facilitated. Further, even if an excessive load is applied to the slide member 101 from the side or the upper side in FIG. 3, the guide rail 100 bears the load, so that the piston 20 should be loaded with these loads via the piston mount 23. Is prevented and the piston 20 is not pressed against the inner surface of the cylinder hole 2a, so that its movement is not impaired. Further, since most of the connecting member 102 overlaps with the outer moving body 26 in the thickness direction, the distance between the lower surface of the slide member 101 and the upper surface of the outer moving body 26 becomes extremely small, and as a result, the rodless cylinder. The height from the mounting surface of the fixed-side member 99 of No. 1 to the upper surface of the slide member 101 can be made very low compared with the conventional one, and it greatly contributes to downsizing of the device. The work of attaching the slide member 101 and the connecting member 102 can be performed even after the slide member 101 is arranged above the rodless cylinder 1. In this case, the slide member 1
01 and the outer moving body 26 are vertically shifted so as not to vertically overlap with each other, the connecting member 102 is fitted into the outer moving body 26, and in this state, the slide member 101 and the outer moving body 26 are inserted.
Are vertically stacked in the axial direction, and the connecting member 102 is fixed to the slide member 101.

いるため、全体の高さを低く抑えることができる。As described above, according to the present application, the sliding member and the driving member are axially fitted to each other by simply fitting the connecting member into the driving member and connecting the sliding member before or after the fitting. Engage with each other, but are connected so that they can move freely in the direction orthogonal to that, so that some vertical and horizontal shifts in the movement path of the slide member and drive member can be absorbed, and both can be combined, making the slide member excessive. Even if a load is applied from the side or from above, the load is not transmitted to the drive member and the drive member can move smoothly. Moreover, both sides in the thickness direction of the connecting member are coupling surfaces with the slide member, and penetrate through the thickness direction to form the mounting screw holes.
Since the connection member is provided, it can be attached without worrying about the front and back of the connection member, and since the connection member is a single member, only the connection member is used other than the fastening means used for connecting the slide member and the connection member. Since it is an extremely simple structure, it can be installed very easily by the user. In addition, most of the connecting members are in the thickness direction.
Most of it overlaps with the outer moving body of the rodless cylinder
Therefore , the overall height can be kept low.
