Abstract:
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.
