[0012] As shown in Fig. 4, the moving part 21 is installed in the housing 5 so as to be movable in the axial direction (left and right direction in Fig. 4) along the guide rail 13. Unloaded circulation paths (not shown) are formed on both sides of the moving part 21 in the width direction (direction of the paper in Fig. 4). Also, guide grooves (not shown) are formed on both side surfaces of the moving part 21.

[0013] As shown in Fig. 4, guide returns 23, 25 are provided at both ends in the front-rear direction (left-right direction in Fig. 4) on one side of the width direction (direction toward the page in Fig. 4) of the moving section 21. Return paths (not shown) are formed within the guide returns 23, 25. Guide returns (not shown) are also provided at both ends in the front-rear direction (left-right direction in Fig. 4) on the other side of the width direction (direction toward the page in Fig. 4) of the moving section 21, and return paths (not shown) are also formed within the guide returns (not shown).

[0014] A plurality of steel balls (not shown) are rolled and circulated in the space between the guide groove (not shown) on one of both side surfaces of the moving part 21 and the guide groove 15 of the guide rail 13, the return path of the guide return 23, one unloaded circulation path of the moving part 21, and the return path of the guide return 25. A plurality of steel balls (not shown) are rolled and circulated in the space between the guide groove (not shown) on the other of both side surfaces of the moving part 21 and the guide groove 16 of the guide rail 14, the return path of one of the guide returns (not shown), the other unloaded circulation path of the moving part 21, and the return path of the other of the guide returns (not shown). With this configuration, the moving part 21 is movable along the guide rails 13, 14.

[0015] Further, a through hole 27 extending in the axial direction is formed in the center of the moving part 21. The front end side (left side in FIG. 4) of the through hole 27 is enlarged in diameter to form a rod attachment part 29, and the rear end side (right side in FIG. 4) of the through hole 27 is enlarged in diameter to form a ball screw nut accommodating part 31. The base end side of a rod 33 is fixed to the rod attachment part 29. The rod 33 has a hollow shape with an opening at the base end side (right side in FIG. 4), and the tip end side (left side in FIG. 4) penetrates the through hole 32 of the front end cap 11 and the felt ring 36 in the through hole 34 of the seal accommodating member 12 to protrude to the outside of the actuator 3. A ball screw nut 35 is accommodated in the ball screw nut accommodating part 31.

The case body 81 is formed with oil supply holes 82, 84 corresponding to the positions of the grease nipples 19, 48 of the accommodated actuator 3. The oil supply holes 82, 84 are closed by an oil supply hole lid 86. The oil supply hole lid 86 is fixed by passing fixing bolts 88 through both end sides of the oil supply hole lid 86 and screwing them into the case body 81.

[0020] The actuator case 1 also has a lid fixing member 87. The lid fixing member 87 is provided on each of both widthwise sides of both end portions of the inner peripheral surface of the case body 81. As shown in Fig. 6, the lid fixing member 87 is formed with a plurality of case body fixing female thread portions 89 extending in the width direction of the lid fixing member 87 (direction from the lower left to the upper right in Fig. 6) and a plurality of lid fixing female thread portions 91 extending in the front-rear direction of the lid fixing member 87 (up-down direction in Fig. 6).

[0021] The lid fixing member 87 is installed on both sides in the width direction of the end side of the inner peripheral surface of the case body 81, and is fixed by passing a fixing screw 93 through the fixing screw through hole 85 of the case body 81 and screwing it into the female threaded portion 89 for fixing the case body of the lid fixing member 87.

A bolt head accommodating recess 103 is formed in each of the four corners of the front surface of the lid 95, and a lid fixing bolt through hole 105 is formed in the bottom surface of the bolt head accommodating recess 103. The lid 95 is fixed by passing a lid fixing bolt 107 through the lid fixing bolt through hole 105 and screwing it into the lid fixing female thread portion 91 of the lid fixing member 87.

[0024] A cable outlet through hole 111 is formed in the center of the lid 97. A cable bushing 113 is installed in the cable outlet through hole 111. An intake and exhaust hole 115 is also formed in the lid 97. An intake and exhaust port 117 is installed in the intake and exhaust hole 115. A lid fixing bolt through hole 119 is formed in each of the four corners of the lid 97. The lid 97 is fixed by passing a lid fixing bolt 107 through the lid fixing bolt through hole 119 and screwing it into the lid fixing female thread portion 91 of the lid fixing member 87.

[0025] Further, packings 121 are interposed between the lids 95, 97 and the end faces of the case body 81, respectively.

[0026] Additionally, the upper surfaces of the lids 95, 97 are arranged contiguously with the upper surface of the case body 81, and the side surfaces of the lids 95, 97 are arranged contiguously with the side surfaces of the case body 81. The lower surfaces of the lids 95, 97 protrude from the bottom surface of the case body 81, and can be used as installation legs. The lids 95 and 97 are made of stainless steel.

[0027] As described above, the actuator 3 is housed in the actuator case 1, and the actuator 3 is fixed by passing the actuator fixing screw 125 through the actuator fixing screw through hole 83 of the case body 81 and screwing it into the fixing female thread portion 17 of the housing body 7. Moreover, the rod 33 passes through a rod through-hole 99 in the lid 95 , with the tip side protruding to the outside of the actuator case 1 .

[0028] Next, the operation of the first embodiment will be described. To accommodate the actuator 3 in the actuator case 1, first accommodate the actuator 3 in the case body 81, and then pass the actuator fixing screw 125 through the actuator fixing screw through hole 83 of the case body 81 and screw it into the fixing female thread portion 17 of the housing body 7 of the actuator 3, thereby fixing the actuator 3 to the case body 81.

[0029] Next, the lid 95 is placed on the front end surface of the case body 81 with a gasket 121 inserted therebetween, and the lid fixing bolt 107 is passed through the lid fixing bolt through hole 105 of the lid 95 and screwed into the lid fixing female thread portion 91 of the lid fixing member 87 installed on the case body 81, thereby fixing the lid 95 to the case body 81. In addition, the lid 97 is placed on the rear end surface of the case body 81 with a gasket 121 inserted therebetween, and the lid fixing bolt 107 is passed through the lid fixing bolt through hole 119 of the lid 97 and screwed into the lid fixing female thread portion 91 of the lid fixing member 87 installed on the case body 81, thereby fixing the lid 97 to the case body 81.

[0030] Next, the effects of the first embodiment will be described. First, by housing the actuator 3 that is not drip-proof and dust-proof in the actuator case 1, it can be easily used as an actuator with drip-proof and dust-proof specifications. In addition, since the lid fixing member 87 is disposed inside the case body 81, the upper surfaces of the lids 95, 97 are disposed contiguously with the upper surface of the case body 81, and the side surfaces of the lids 95, 97 are disposed contiguously with the side surfaces of the case body 81, the outside has a shape with few irregularities, dust is less likely to accumulate, and the actuator is easy to clean, so that it can be easily kept clean. This allows the actuator 3, which is not dust-proof or drip-proof, to be easily modified to a specification suitable for use in food or pharmaceutical manufacturing sites.

[0031] Furthermore, since the lids 95, 97 are made of stainless steel, they are corrosion-resistant and can be more easily kept clean. Moreover, the case body 81 only requires simple processing of holes, and can be easily manufactured.
