The fixing protrusions 116 are coupled to the second fixing holes 18b in a pin manner so that the guide members 110 can be disposed at the precise positions of the rim portions 11a, 12a, and 13a. Since the fixing projections 116 and the second fixing holes 18b are fixed in a pin fixing manner, the guide member 110 So that the upper cover 80 coupled to the guide member 110 through the receiving hole 80a is stably supported without being moved back and forth and left and right.

The guide member 110 may be manufactured through an injection molding process, and the material may be rubber or plastic having elasticity.

A spring holder 122 and a fixing bracket 124 for fixing the upper cover 80 disposed at an accurate position by the guide member 110 may be further provided on the rim portions 11a, 12a, and 13a.

The spring holder 122 is provided on at least one rim portion 11a formed in the front frame 11 so that the front end of the upper cover 80 is caught by the elastic force of the spring holder 122, (11, 12, 13). The fixing bracket 124 is screwed to the upper cover 80 and the rear frame 12 to connect and fix the upper cover 80 and the rear frame 12 to each other.

Meanwhile, in the control device receiving portion 86 coupled to the rear of the upper cover 80, noise included in electrical signals generated in various devices disposed inside the frames 11, 12, and 13 is removed The noise filter 150 is combined.

FIG. 6 is an enlarged perspective view showing an enlarged portion 'B' in FIG. 3, and FIG. 7 is a sectional view showing a noise filter mounted on the filter mounting portion.

3 and 6 to 7, the noise filter 150 is mounted on the filter mounting portion 88 of the control device accommodating portion 86 and fixed to the upper cover 80.

The control device receiving portion 86 includes a filter mounting portion 88 to which the noise filter 150 is mounted. The filter mounting portion 88 is open at one side to receive and engage the noise filter 150 and a coupling protrusion 154 formed in the noise filter 150 is passed through the lower surface 88a of the filter mounting portion 88 A through hole 88b is provided.

The noise filter 150 includes a filter main body 152 provided in a cylindrical shape and a coupling protrusion 154 protruding forward by a predetermined length from one side of the filter main body 152. The coupling protrusions 154 are configured to fix the noise filter 150 to the upper cover 80, and the outer circumferential surface thereof is male-threaded.

The upper cover 80 includes a coupling hole 88c to be engaged with the coupling projection 154. [ The fitting hole 88c is provided at a position corresponding to the through hole 88b provided in the lower surface 88a of the filter mounting portion 88 and the inner circumferential surface of the fitting hole 88c is threadedly threaded with the engaging projection 154 . The upper cover 80 is made of a material such as iron that allows current to pass therethrough so that the noise filter 150 can be grounded while being coupled and fixed.

Since the noise filter 150 can be easily assembled to the upper cover 80 using the screw coupling method and a separate component or structure for assembling the noise filter 150 is unnecessary, the assembling time is shortened and the material cost is reduced Productivity is improved.

The foregoing has shown and described specific embodiments.
