摘要： In a power transmission 1 in which a pulley 2 and a hub 5 are engaged with each other, in protrusions 51 of the hub 5 side and in protrusions 22 of the pulley 2 side located on an outer circumferential side with respect to an outer hub 53, an annular dust flange 51d is provided which protrudes and expands to the outside in the radial direction from a front side portion which adjoins protrusions 51c of an elastic portion 52. When an outer circumferential end of this dust flange 51d is elastically, tightly contacted with a sealing portion 23 of the pulley 2, a front face of the protrusions 22 can be completely covered.

摘要： The power transmission device (10) comprises: a rotatable rotary part (1) to which a rotary driving force is transmitted from a driving source; and a power transmission shut-off member (3) for preventing an excessive torque from being transmitted between the rotatable rotary part and a rotating shaft (4) of a driven apparatus and threadedly coupled to the rotating shaft. A hub (2) arranged between the rotary part and the power transmission shut-off member to connect them is located between the power transmission shut-off member and the rotating shaft. The power transmission device further comprises a washer (6) located so as to be sandwiched between the hub and the rotating shaft. The washer is separated from the hub, which is not sandwiched between the washer and an end surface (308) of the power transmission shut-off member near the rotating shaft.
