Abstract
A cover of an internal combustion engine includes a cover body to be mounted to a crankcase of the internal combustion engine. The cover body includes a through hole, a protruding part, and a plurality of first recessed grooves. The through hole is to support a shaft rotatably. The protruding part is provided above the through hole in an upward direction of the internal combustion engine and protrudes toward an inside of the cover body facing the crankcase. The protruding part includes a first upper part and a first lower part in the upward direction on an inner surface of the protruding part facing the crankcase. The plurality of first recessed grooves extend radially from the through hole so as to connect the upper part and the lower part of the protruding part.

A cover member to be mounted on a crankcase of an internal combustion engine comprising a through hole for rotatably supporting a shaft, a protruding part being positioned above the through hole and protruding toward an inside of the cover member, and a plurality of recessed grooves extending radially from the through hole so as to provide a connection between an upper part and a lower part of an inner surface side of the protruding part.
A cover of an internal combustion engine, comprising:
- a cover body to be mounted to a crankcase of the internal combustion engine, the cover body comprising:
- a through hole to support a shaft rotatably;
- a protruding part provided above the through hole in an upward direction of the internal combustion engine and protruding toward an inside of the cover body facing the crankcase, the protruding part including a first upper part and a first lower part in the upward direction on an inner surface of the protruding part facing the crankcase;
- and
- a plurality of first recessed grooves extending radially from the through hole so as to connect the upper part and the lower part of the protruding part.
A cover of an internal combustion engine, comprising:
- a cover body to be mounted to a crankcase of the internal combustion engine, the cover body comprising:
- a through hole having a center axis to rotatably support a shaft about the center axis, the cover body having an axial direction in which the center axis extends and a radial direction perpendicular to the axial direction, the cover body having a cover body inner surface to face the crankcase and a cover body outer surface opposite to the cover body inner surface in the axial direction, the axial direction including an inward direction directed from the cover body outer surface to the cover body inner surface;
- a protruding part which is connected to the cover body and positioned apart from the through hole in the radial direction, the protruding part protruding from the cover body inner surface in the inward direction, the protruding part having a protruding part inner surface connected to the cover body inner surface and a protruding part outer surface connected to the cover body outer surface, the protruding part inner surface having a first inner periphery facing the through hole in the radial direction and a first outer periphery opposite to the first inner periphery in the radial direction;
- and
- a plurality of inner recessed grooves extending in the radial direction from the first outer periphery of the protruding part to the first inner periphery of the protruding part.
