2. Description of the Related Art Conventionally, for example, a manifold 104 and a valve 106 constituting a manifold 102 of a valve manifold 100 shown in FIG. 4 are provided with bolts 1 at upper and lower ends of a resin manifold 104 as shown in FIG.
08 through the bolt 108 and the resin valve 106
Are connected by screwing into two screw holes (not shown) formed in the end face. Further, the valve manifold 100 using the above-described manifold unit 102 is used.
The structure and operation of the valve manifold 100 will be described with reference to FIG. 4. In general, the valve manifold 100 has a structure in which a plurality of manifolds 102 are sandwiched between a pair of support blocks 110 from both sides. An inflow port 112 is provided on the front wall surface of each support block 110, and an outflow port 114 is provided on the upper surface. (Shown). With this structure, the inlet 1
Fluid flowing from the manifold 12 is supplied to each of the manifolds 102, and two pipe joints 116 formed in the manifold 104 by operating a pilot valve (not shown) incorporated in a valve 106 of each of the manifolds 102.
Has a function of supplying a fluid to any one of tubes (not shown) connected to the. The fluid discharged from each manifold 102 is discharged from the outlet 114.

[0003]

However, in the above-described connection structure, it is necessary to tighten two bolts to connect the manifold and the valve, which is troublesome. In addition, after installing a valve manifold using multiple manifolds alone and piping tubes to the fittings of each manifold alone, when replacing only the manifold due to failure etc., it is difficult to remove the bolts on the lower side of the tube There is a problem that replacement takes time. Therefore, the present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide a connection structure that can easily and easily connect two members.

[0004]

The present invention has the following arrangement to achieve the above object. That is, in the connection structure for connecting the first member and the second member via the connection means, the connection means is provided on one end side of the first member, and is connected to the second member. First moveable / separable
A movable member provided on the other end side of the first member, capable of moving toward and away from the second member, and capable of being hooked to the second member; A fulcrum part of the first member provided between the first movable member and the second movable member, an elongated part, one end of which is hooked to the first movable member, and An end portion is hooked on the second movable member, and abuts on the fulcrum portion at an intermediate portion,
A first movable member which is inserted between the first movable member and the second member, and which is rotatable about a fulcrum, and which is rotated in the fastening direction; And a bolt for moving the member in the direction of the second member.

[0005]

The second movable member of the connecting means provided on the first member is engaged with the second member. When the bolt inserted between the first movable member and the second member is rotated in the tightening direction, the first movable member moves toward the second member. With the movement of the first movable member in the direction of the second member, the lever portion having one end portion hooked on the first movable member rotates about the fulcrum portion, and the other end portion of the lever portion becomes the second portion. The second movable member is moved in a direction away from the second member. Thereby, the second member is attracted to the first member and is connected.
