Has a through hole 12 formed therein, and the hole 12
The bolt 13 can be inserted into.

A spacer holder 14 made of a steel plate is attached between the engagement pieces 4 and 5, and the holder 14 is formed in a U-shaped cross section that can engage with the end plate 3, and the upper ends of the pair of side pieces 14a. Is engaged with the engaging piece 4 and the lower end thereof is hooked on the engaging piece 5.

An opening window 15 having substantially the same diameter as the head diameter of the bolt 13 is opened at the side end portion of the side piece 14a, and an engaging edge 16 is formed to bulge at the periphery of the opening portion of the window 15, and the edge is formed. The collar portion 11 is accommodated inside the 16 so as to be engageable.

In the figure, 17 and 18 are hemispherical engagement protrusions provided at the upper and lower positions of the engagement edge 16, which are engageable with the engagement protrusions 8 and 9, and 19 is a mounting provided on the vehicle side. A plate, 20 is a nut, and 21 and 22 are a flat refrigerant tube and a radiation fin that constitute the condenser core 2.

(Operation) The capacitor mounting structure configured in this manner does not require a bracket and a new mounting component that have been frequently used in the related art, and thus the structure is simplified.

That is, the end plate 3 having the engagement pieces 4 and 5, the through hole 7, and the engagement projections 8 and 9 formed at predetermined positions, the spacer 10,
A bolt 13 and a spacer holder 14 are prepared and attached when the capacitor 1 is assembled.

For example, after the capacitor 1 is assembled, the spacer 10 is inserted into the through hole 7 of the end plate 3 and the through hole 12 of the spacer 10 is inserted.
After inserting the bolt 13 into the, the spacer holder 14 is fitted from the side of the end plate 3 and the upper end of the side piece 14a is engaged with the engaging piece 4
And the end plate 3 and the side piece 14
The lower end of a is engaged with the engagement piece 5, and the holder 14 is further pushed in under this engagement state.

By doing so, the engaging edge 16 moves on the outer peripheral surface of the collar portion 11 of the spacer 10, and after that, when the inner surface of the spacer holder 14 comes into contact with the side end surface of the end plate 3, the engaging protrusion 1
7, 18 are fitted to the engaging projections 8, 9, and the spacer holder 14 is in close contact with the peripheral surface of the end plate 3 to prevent the spacer holder 14 from falling off from the peripheral surface of the end plate 3, while the collar portion 11 of the spacer 10 is prevented. Engages with the inner surface of the engaging edge 16 to prevent the spacer 10 from falling off.

Since the spacer holder 14 is in close contact with the peripheral surface of the end plate 3 as shown in FIG. 1, the capacitor thus assembled does not project from the end plate 3,
Moreover, the bolts 13 are still inserted in the spacers 10, so to speak, they are placed in a state where they are immediately attached to the vehicle.

Next, when the capacitor 1 is attached to the vehicle, the capacitor 1 is positioned at a predetermined position in the engine room, for example, the bolt 13 is inserted into the vehicle-side mounting plate 19, and the nut 20 is screwed to the shaft end of the mounting plate 19. This should be tightened.

As described above, according to the present invention, since the capacitor 1 is immediately placed in the mounted state, the above-described mounting work can be performed simply and quickly, and the capacitor 1 can be directly mounted substantially through the end plate 3. Therefore, as described above, the brackets and the dedicated mounting parts that have been frequently used in the past are not necessary, and since there is no special protrusion on the peripheral surface of the capacitor 1, it is easy to secure the installation space and In addition to being suitable for densely accommodating the engine room, the mounting work can be efficiently performed by avoiding contact with adjacent equipment.

(Advantages of the Invention) As described above, the capacitor mounting structure of the present invention has a pair of engaging pieces and a through hole formed in the end plate, and a spacer having a collar portion is provided in the through hole so that the spacer can be inserted. Since the bolts can be inserted into the spacers, the capacitors can be directly attached through the end plates, and there is an effect that a bracket and a dedicated attachment part which have been frequently used conventionally can be unnecessary.

Further, in the present invention, a spacer holder having a U-shaped cross section which can be engaged with the end plate is provided, an opening window is provided in a pair of side pieces of the holder, and upper and lower ends of the side pieces can be engaged with the engagement pieces. In addition, since the engaging edge is provided on the peripheral edge of the opening of the opening window and the flange portion of the spacer is accommodated in the inner surface of the engaging edge so as to be engageable, the spacer holder is immediately attached to the vehicle or the like. There is a practical effect that a capacitor can be easily attached by being attached to the end plate.
