In a conventional automatic transmission with a control valve mounted above, as shown in FIG. 1, a flange portion 3 is formed at the end of the valve cover 2 attached to the transmission body 1 for strength reinforcement. This flange portion 3 is generally bent downward as shown in FIG. 1 to prevent water from accumulating, but as shown in FIG. If not, the flange part 3 is bent upward (ForD's
(See ATX transaxle). However, in this case, rainwater, sewage, dilute sulfuric acid from battery liquid, etc. accumulate in the flange, making this part susceptible to corrosion. In order to prevent this, if the flange part is removed, the rigidity of the mounting part will be reduced, so in order to maintain sealing performance, it will be necessary to increase the thickness of the plate or reinforce it with separate parts such as a lane force, resulting in an increase in cost.

The purpose of this invention is to solve these problems with conventional valve covers, and to provide a simple and inexpensive structure for mounting the valve cover in places where there is no space for forming a downward flange while providing sufficient strength to the upper surface. To obtain a valve cover which can prevent water from accumulating in the valve cover.

In order to achieve this object, the valve cover of the present invention is characterized in that an upwardly directed flange is provided on the mounting edge, and a water drain portion is provided in this flange.

The figure shows a cross section taken along the line A--A in FIG. The flange portion 3 of the attachment portion of the valve cover 2 is bent upward, and a drain hole 5 is formed in the bent portion. The drain hole 5 may be formed by drilling with a drill or the like, but it is more preferable to form it by a pressing process during press molding of the valve cover 2. Specifically, when the valve cover 2 is in the form of a flat plate, the drain hole 5 is first punched using a press, and then the flange portion 3 is bent using a press. The shape of the drain hole 5 is 3rd and 4th.
In addition to the rectangles shown in the example of the figure, Figure 5 a, b, c
Various shapes can be used, such as a triangle, a square whose diagonal line is aligned with the flange bending direction, and a circle as shown in FIG.

As detailed above, the valve cover of the present invention has a flange bent upward at the mounting edge of the valve cover, and a water drain part is provided in this flange, so there is no space for forming the downward flange. It can be installed even in places where there is no flange, and it can maintain sufficient rigidity to maintain the sealing performance of the valve cover without increasing the plate thickness or installing a separate member, and it also prevents water from accumulating inside the flange. Since corrosion can be reliably prevented, the corrosion resistance of this part can be improved, and since the structure is simple and manufacturing is easy, it has the advantage that it can be provided at low cost.
