Abstract

A protruding portion is formed on a rear side of a side plate, namely a side surface forming guide passage. The protruding portion is intended to prevent a thrust metal from being put to the guide passage with the left and right ends being in the wrong position. Accordingly, a height of the protruding portion is smaller than a depth of the oil ditch of the thrust metal, the width of the protruding portion is smaller than the width of the oil ditch. Also, regarding to the formation position of the protruding portion, when the thrust metal is truly set to guide passage, the center of the protruding portion approximately accords with the center of the oil ditch of the thrust metal.

First claim

The invention claimed is:

1. A combination comprising: a semi-circular thrust metal and a jig for supplying the semi-circular thrust metal into a storing ditch of a crank shaft, the thrust metal having a groove that functions as an oil ditch on a one side surface,
the jig comprising a guide passage configured to drop the thrust metal into the storing ditch, an inclined surface being formed on a bottom end of a right side or a left side of the guide passage, the inclined surface configured to cause the falling thrust metal to jump and be raised diagonally, and one side of an opposed face forming the guide passage is provided with a protruding portion, wherein the height of the protruding portion is smaller than the depth of the oil ditch formed in the thrust metal, and the width of the protruding portion is smaller than the width of the oil ditch.

2. The combination according to claim 1 , wherein the jig is provided with a side plate in each side surface of a main body, the guide passage is formed between the main body and the side plate, and the protruding portion is formed in an inboard surface of the side plate.

3. The combination according to claim 1 , wherein a top plate is attached to a top surface of the main body, and an aperture and the protruding portion of the guide passage are formed to the top plate.

4. The combination according to claim 2 , wherein a side surface of the main body includes a recess, and the side plate covers the recess.

5. The combination of claim 1 , wherein the bottom end of the guide passage is formed as a semicircular recess sized to fit over the crank shaft.

6. The combination according to claim 1 , wherein the thrust metal forms in a flat on the other side surface, and the side surface on which a recess of the oil ditch is formed always faces in one direction.
