することがある。 In many cases, the oil pan is screwed to the mounting surface at the bottom of the cylinder block, and its oil reservoir and oil recovery section are usually smaller than the mounting surface to the cylinder block, but especially when a large amount of oil is If necessary, make the oil pool deeper,
Capacity is increased by welding a separate part wider than the mounting surface. Among these, when deepening the oil reservoir, there are problems such as a reduction in the minimum ground clearance of the vehicle due to the increase in the height of the oil pan, damage caused by flying stones or contact with the road surface, and the need to weld separate parts. In some cases, there were many problems such as cracks easily forming in the welded parts due to vibration etc., making it difficult to ensure the quality of the product. Also, the oil pump or oil pump suction port is inserted into the oil pool,
Air is sucked in from the suction port due to the wave motion of the oil surface caused by the vehicle's tilt, acceleration and deceleration, and there is a risk of poor lubrication.In order to prevent the wave motion of the oil surface, a small plate called a "batsuful" is installed with the same capacity as above. In some cases, a separate member may be further welded to the upper surface of the oil pool in addition to the member provided as a precautionary measure.

材が締付工具と干渉し取付がむずかしい。 The conventional assembled type oil pan as described above is shown in FIGS. 1 to 5. In the oil pan shown in FIGS. 1 to 3, a second oil reservoir member 2 is welded to the outside side of a first member 1, and a third buttful member 3 is welded inside the first member 1. (Welded parts a, b, c). However, as is clear from the figure,
There was a problem in that the welding lines were complicated because there were three components and because the entire oil pan had to be bolted to the lower surface of the cylinder block, which was narrower than the inner width of the oil pan. Figures 4 and 5 are
This is another example of a conventional oil pan, and as shown in the figure, an oil reservoir member 5 is welded to the lower part of a first member 4, and this oil reservoir member 5 is divided into two members. Although the welding line is somewhat simpler than that of the conventional example, it is still difficult to weld (welding part d,
Because of the large amounts of e, f, g), there was a drawback that cracks were generated from the welded portion. There were also problems due to the increase in height as described above. Furthermore, in any of the oil pans shown in FIGS. 1 to 5, when the oil pan is attached to the cylinder block, the second member interferes with the tightening tool, making it difficult to attach the oil pan to the cylinder block.

両構造上必要な空間である。 The present invention will be explained below with reference to the drawings. FIG. 6 is a plan view showing an embodiment of the assembled oil pan of the present invention. C-line sectional views are shown in FIGS. 8 and 9, respectively. In FIGS. 6 to 9, 7 is the first member, 8 is the second member, 9 is a bolt for tightening the first member and the second member, 10 is the cylinder block of the engine, and 11 is the first member 7. This is a bolt for attaching the cylinder block 10 to the cylinder block 10. Furthermore, 12 is the second member 8
13 is a molded part of the first member 7 and has a buffing function, 14 is an oil pump oil suction pipe hole inserted into the oil pool 12, and 15 is a hole for collecting oil falling from the cylinder block again. The groove 16 for flowing water into the pool portion 12 is a necessary space in terms of vehicle structure.

The second member 8 having a diameter can be larger than the cylinder block mounting surface, and the first member 7
It serves to close a part of the upper surface of the member 8 and to fix it to the cylinder block. Therefore, the first
The outer shape of the member has approximately the same shape as the upper opening of the second member. This first member has an opening corresponding to the mounting surface of the cylinder block to receive oil from the cylinder block, and is shaped to cover the upper part of the oil reservoir of the second member at an appropriate height. has been done. In this example, the second member 8 is attached to the first member 7 with bolts 9, so that the joint surfaces of the cylinder block 10, the first member 7, and the second member 8 are on the same plane. By doing so, the mutual adhesion of the mating members to be fastened is reliably maintained.

とも更に利点として挙げられる。 In the present invention, since the first member and the second member are not joined by welding or the like, there is no problem of cracking from the welded portion as in the conventional case, and the mechanical strength of the product is improved. In addition, since the second member can be appropriately made wider than the cylinder block fastening surface,
Since the depth of the oil pan does not need to be increased excessively, problems such as a reduction in minimum ground clearance and damage caused by flying stones or contact with the road surface can be solved. Furthermore, the oil accumulated in the oil reservoir 13 of the second member 8 and the oil waves caused by the shaking of the entire engine are suppressed to a minimum by the buff-full portion 13 of the first member 7 from above. This can further prevent engine lubrication failure. Furthermore, since the oil pan of the present invention only needs to be assembled with the first member and then the second member, the installation work is not obstructed by oil pools as in the past, and assembly is very easy. Another advantage is that
