For example, FIG. 7 shows an electric valve actuator A for driving an electric valve that is installed in piping of an oil plant or the like,
An object to be fixed 2 mainly including a control panel 2a is integrally assembled in a housing 1 which is a container. Specifically, the object to be fixed 2 is formed by rigidly contacting a substrate 22 with a front plate 21, which is a front end, and mounting the control panel 2a on the substrate 22. Then, the fixed object 2 is inserted into the housing 1 through the housing opening end 1a, and the front plate 21
The inner surface of the housing is brought into contact with the step portion 1b provided on the front end side of the housing 1, and the front plate 21 is fixed by the bolt 3 to the housing step portion 1
It is fastened and fixed to b, and finally the opening 1a is closed by the lid 4 to complete the attachment work.

態が解消されないという問題がある。However, in such a mounting structure, the fixed object 2 is supported cantilevered on the front plate 21 thereof, and the rear end side is not restrained at all, and the free end is free. Becomes For this reason, there is a problem that vibration of the electric valve actuator A easily causes looseness of each portion, loosening of the bolt 3, etc., which may cause damage to parts of the control panel 2a and eventually cause failure of the main body of the electric valve actuator A. is there. Moreover, in the mounting procedure, the terminal plate 5 is first attached to the opening 1c on the rear end side of the housing 1 and is closed by the lid 6, so that this one wants to reinforce the rear end side of the fixed object 2. It is impossible to modify it at all, and at most, as shown in FIG. 8, the number of bolts 3 for fastening the front plate is limited to three, and the unstable mounting state described above is not resolved. There's a problem.

While being guided along 11, the fixed object 2 is inserted into the housing 1 up to the position in FIG. 1 where the front plate 21 contacts the housing step portion 1b. Next, open end 1
A driver (not shown) is inserted into the housing 1 from the side a, the screw 73 is engaged with the cross groove 73b of the bolt head 73a and tightened, and the bolt 73 is screwed into the screw hole 72 of the guide member 24. Along with this, the bolt head 73a presses the lower edge 71b side of the pressing metal fitting 71, and causes the pressing metal fitting 71 to rotate about the upper edge 71c side as a fulcrum, as shown in FIG. The pressing fitting 71 is erected (that is, protrudes downward) to a substantially vertical posture, and the lower edge 71b thereof is pressed against the housing inner wall 1d. And the guide member 2 is generated by the pressing reaction force.
Press 4 upwards. As a result, the guide member 2
As shown in FIGS. 5 and 6, the upward surface 24a of the No. 4 abuts on the locking surface 11a of the guide rail 11, and as a result, the fixed object 2 is constrained to the housing 1 side at that portion. Finally,
As shown in FIG. 1, the bolt 3 inserted into one location of the front plate 21 is fastened to the housing step portion 1b to complete the mounting work.

することができる。In this way, the fixing mechanism according to the present embodiment surely fixes the fixed object 2 to the housing 1 at the two front and rear positions, even though the work is performed only through the opening 1a of the housing 1. , It is possible to improve the support strength by eliminating the cantilevered mounting state. Therefore, the control panel 2
It is possible to improve vibration resistance during operation of the electric valve actuator A as a whole including a, and effectively avoid damage to parts due to looseness of various parts and loosening of bolts, failure of the electric valve actuator A, and the like. Further, in such a case, by simply inserting the screwdriver again from the opening end 1a and loosening the bolt 73, the pressing fitting 71 is laid down in the state of FIG. 4, and in that state, the bolt 3 of the front plate 21 is loosened. hand,
The fixed object 2 can be easily taken out of the housing 1. Moreover, since it is not necessary to bolt the front plate 21 at three points as in the conventional case, the attaching / detaching operation can be simplified.
