A structure for preventing movement of pivot bearings used in vehicular wiper devices, wherein a pivot shaft is rotatably supported by a sleeve mounted on a vehicle body through the intermediary of a pair of bearings at a predetermined axial spacing from each other. The pivot bearing fixing structure comprises slits formed in facing end surfaces of the bearings so as to divide the end portion of each bearing into an inner circumferential portion and an outer circumferential portion, ridges protruding inward radially from an inner surface of the inner circumferential portion of each bearing, the ridges being notched at a predetermined circumferential spacing so as to be elastically deformable radially outward, and recesses provided on an outer circumferential surface of the pivot shaft so as to receive the ridges thereby to fix the bearings against axial movement.
A pivot bearing fixing structure for use in a vehicular wiper device of the type having a wiper arm, a pivot shaft to which said wiper arm is integrally fixed at its base end, a sleeve stationarily mounted on the vehicle body, and a pair of bearings press-fitted in said sleeve positioned at a predetermined axial spacing from each other, said bearings rotatably supporting said pivot shaft, said pivot bearing fixing structure comprising:
A pivot bearing fixing structure, comprising:
A pivot bearing for supporting a shaft in a sleeve, comprising:
