Lubricating oil collecting and guiding device

1. A lubricating oil collecting and guiding device for collecting lubricating oil inside a transmission case and guiding the collected lubricating oil to lubrication parts inside the transmission case, comprising:

an elongated gutter-shaped main unit including a pair of side wall parts facing each other, and a support part extending outwardly from one of the pair of side wall parts and having a flat board-form part formed on a front side thereof and a pressing face part formed on a rear side thereof; and

a plurality of held parts provided on the main unit, including a press-in projection integrally formed on the flat board-form and projecting from the flat board-form part in a direction away from the support part, the press-in projection being pressed into a press-in hole formed on an open side end face of said transmission case by pressing the pressing face part and held in a tightly fitted state, and an insertion projection freely inserted into an insertion hole formed for positioning on a bottom part side of said transmission case and held in a loosely fitted state;

wherein the main unit is adapted to be placed above a serial gear group received inside the transmission case having a bottomed cylindrical shape when the plurality of held parts is held on the transmission case, and

said insertion projection has a projection length from said main unit longer than that of said press-in projection from said main unit, and said insertion projection has an insertion length inserted into said insertion hole longer than that of said press-in projection inserted into said press-in hole in an installed state, wherein the press-in projection has a shaft part, and wing parts radially outwardly extending from an outer perimeter portion of the shaft part and having a diameter larger than that of the press-in hole; and the insertion projection has a center portion, and wing parts outwardly extending from the center portion to form a cross shape and having a diameter smaller than that of the insertion hole.

2. A lubricating oil collecting and guiding device according to claim 1 , wherein the support part is provided on one end in an elongated direction of said main unit.

3. A lubricating oil collecting and guiding device according to claim 2 , wherein the pressing face part is formed to align in one plane with the one end of said main unit.

4. A lubricating oil collecting and guiding device according to claim 1 , wherein said press-in projection has a brush clip shape.

5. A combination comprising:

the lubricating oil collecting and guiding device according to claim 1 , and the transmission case including the press-in hole formed on the open side end face thereof and the positioning insertion hole formed on the bottom part side thereof.

6. A lubricating oil collecting and guiding device for collecting lubricating oil inside a transmission case and guiding the collected lubricating oil to lubrication parts inside the transmission case, comprising:

an elongated gutter-shaped main unit; and

a plurality of held parts provided on the main unit, including a press-in projection pressed into a press-in hole formed on an open side end face of said transmission case and held in a tightly fitted state, and an insertion projection freely inserted into an insertion hole formed for positioning on a bottom part side of said transmission case and held in a loosely fitted state;

wherein the main unit is adapted to be placed above a serial gear group received inside the transmission case having a bottomed cylindrical shape when the plurality of held parts is held on the transmission case;

said insertion projection has a projection length from said main unit longer than that of said press-in projection from said main unit, and said insertion projection has an insertion length inserted into said insertion hole longer than that of said press-in projection inserted into said press-in hole in an installed state;

the main unit includes a screen board integrally formed on one end in an elongated direction of the main unit and a first support part extending outwardly from the screen board in a direction same as that of the screen board;

the first support part includes a flat board-form part formed on a front side thereof, and lattice-form rib parts having a horizontal row and vertical rows intersecting to the horizontal row and formed on a back side thereof; and

the press-in projection projects from the flat board-form part in a direction away from the first support part.

7. A lubricating oil collecting and guiding device according to claim 6 , wherein the main unit includes a second support part integrally formed on a middle portion in the elongated direction of the main unit and extending outwardly in a direction opposite to the extending direction of the first support part, and the second support part includes a front face; and

the insertion projection projects from the front face in a direction away from the second support part.
