PURPOSE:To protect a torsional damper from leaking oil by providing a capture part for catching the leaking oil as well as a discharge passage for discharging leaking oil caught at the capture part below a fitting member in the non-contact region with an elastic member provided on the upper face of the fitting member. CONSTITUTION:Leaking oil leaking around a crankshaft from a crank chamber is caught at a capture part 35 provided at the fitting member 32 of a torsional damper 30 and then discharged below the member 32 from a discharge passage 36 provided at the member 32. In this case, the capture part 35 and the discharge passage 36 provided at the member 32 are disposed in the non-contact region with an elastic member 33. Accordingly, the leaking oil is not brought into contact with the elastic member 33 in the discharge process, so that swelling or degradation caused by the contact with oil is not generated to the elastic member 33, thus protecting the damper 30 and securing vibration damping performance. |
