  • vibration in portions of the bottom plate 25 of the oil pan 9 due to impact force during operation of the engine 1 is prevented, which prevents generation of noise from the oil pan 9.
  • noise generation from the oil pan 9 described above is prevented because of the bottom plate 25 being formed approximately in agreement in shape with part of the spherical surface 34 and not because of a vibration absorbing plate or numerous ribs being separately provided, and therefore the prevention of noise generation from the oil pan 9 can be achieved with simple structure and without increasing the weight of the oil pan 9.
  • the center 33 is disposed in the vicinity of the vertical line 23 passing through a laterally central portion 36 of the bottom plate 25, as viewed along the axial center 4 of the crankshaft 3 (Figs. 2, 5, and 6).

  • the dimension from the center 33 to the under surface of the bottom plate 25 in the shape approximately in agreement with part of the spherical surface 34 is 35-45 cm. If it is less than 35 cm, the vertical dimension of the engine 1 is apt to be too large because of the central portions 36, 37 of the bottom plate 25 being protruded downwardly to a large extent, and if it is over 45 cm, improvement in rigidity is hindered because of the bottom plate 25 being too flat.
  • part of the bottom plate 25 is formed to be a circular flat plate 40 extending approximately in the horizontal direction.
  • the upper surface of the flat plate 40 is at the inner lowermost end of the oil pan 9, and approximately upwardly of the flat plate 40 is disposed the inlet 20 of the suction section 18.
  • the diameter of the flat plate 40 is approximately 8-10 cm.

Therefore, even if the inclination of the liquid surface of the oil 8 in the oil pan 9 changes back and forth or leftwardly and rightwardly while the vehicle is running, for example, the suction section 18 is located more reliably in the oil 8 at all times. Thus, the oil 8 is sucked more reliably into the oil pump 12 through the suction section 18, securing given lubrication by the oil 8.
  • the flat plate 40 is disposed at a position offset from the central portion 41 of the bottom plate 25, as described above, which suppresses vibration of large amplitude in the flat plate 40.

  • the beads 44 causes the rigidity of other portions of the bottom plate 25 to be improved, and the less rigid flat plate 40 is reinforced by the beads 44.
  • vibration in portions of the bottom plate 25 including the flat plate 40 is suppressed further, which prevents noise generation from the oil pan 9 further.
  • grooves 45 In the upper surface of the bottom plate 25 at other portions are formed grooves 45 by the inside surfaces (upper surfaces) of the beads 44, and ends of the grooves 45 on the side of the flat plate 40 are formed in communication with a region above the flat plate 40. Also, the grooves 45 are each formed to be inclined gradually downwardly toward the ends.
  • a portion of the bottom plate 25 below the oil pump 12 of the component 11 bulges downwardly and forms a bulging portion 47.
  • the bulging portion 47 is formed approximately in the shape of part of a cylinder located in the oil pan 9 and having an axial center 48, approximately parallel to the axial center 4 of the crankshaft 3, in its center.
  • the bulging portion 47 is connected, at one end in the axial direction, to the front vertical wall 26 and, at the other end, to the outer edge of the flat plate 40.
  • the bulging portion 47 of large rigidity is provided approximately in agreement in shape with part of the cylinder, the rigidity of the bottom plate 25 is improved.
  • the end of the bulging portion 47 is connected to the outer edge of the less rigid flat plate 40, and the flat plate 40 is reinforced by the bulging portion 47. Thus, vibration in portions of the bottom plate 25 including the flat plate 40 is prevented.
  • the inner bottom of the bulging portion 47 is inclined, in its axial direction, gradually downwardly toward the flat plate 40, therefore the oil 8 is prevented from remaining in the bulging portion 47.
  • the lower part of the oil pump 12 of the component 11 is fitted inside the bulging portion 47, and therefore the oil pump 12 of the component 11 and the oil pan 9 are arranged compactly together with each other, effecting size reduction of the engine 1.
