This shaft sealing device comprises: a housing that has a storage groove; a seal body stored in the storage groove; and a projected part that projects from one of the housing and the seal body toward the other in the storage groove in an axial direction. The seal body divides an annular space into a high-pressure region on a first side in the axial direction and a low-pressure region on a second side in the axial direction. The housing has a connection part that connects the low-pressure region with the inside of the storage groove. The projected part divides a portion between an opposite surface and a low-pressure-side lateral surface of the seal body into a first space on the radially outer side and a second space on the radially inner side. The connection part connects the first space with the low-pressure region.

The present invention relates to a pivot assembly for a vehicle wiper system. The assembly includes a pivot shaft rotatably supported in central passage of a pivot housing, a lever coupled to the pivot shaft, and a cover. The cover includes a tubular portion, cylindrical step and a transition portion integrally formed between the tubular portion and the cylindrical step. The cover further includes a cantilever snap extending from inner surface of the transition portion, in longitudinal direction of the cover. A protrusion is formed in the cylindrical step at a location adjacent to the snap. The tubular portion of the cover is received over pivot shaft and a locking profile formed at free end of the snap is received in a recess formed in top end of the pivot housing, thereby restricting longitudinal and rotational movements of the cover with respect to the pivot housing.
