Abstract:
[Problem] Provided is a driving force transmission device capable of improving workability of spline engagement between a plurality of inner clutch plates and a shaft during assembly. [Solution] A driving force transmission device (10) includes: a main clutch (5) having a plurality of outer clutch plates (51) and inner clutch plates (52); a clutch housing (2) that comes into spline engagement with the plurality of outer clutch plates (51); a pinion gear shaft (4) that comes into spline engagement with the plurality of inner clutch plates (52); and a main cam (61) for pressing the main clutch (5) in an axial direction. The clutch housing (2) is in the shape of a bottomed cylinder having a cylindrical portion (21) and a bottom portion (22) to accommodate the main clutch (5). A plurality of screw holes (221) extending axially is formed in the bottom portion (22) of the clutch housing (2), and at least one of the screw holes (221) passes axially through the bottom portion (22) at a position axially aligned with the plurality of inner clutch plates (52).
