Abstract
A wiper blade (18a) has a rubber holder (22) for holding a blade rubber (21). This rubber holder (22) has a connection block (24) coupled to a wiper arm and two sub-holders (25) fixed on both sides of the connection block (24), and the sub-holders (25) each has two rod-shaped spring members (27) curved with curvature radii smaller than that of a front glass and 11 holder pieces (26) fixed to these rod-shaped spring members (27) in a longitudinal direction at a predetermined interval. Further, this rubber holder (22) is formed so that the two sub-holders (25) are coupled to each other via the connection block (24) in the longitudinal direction.
Claims7
A wiper blade attached to a wiper arm provided swingably to a vehicle to perform a swinging motion on a windshield glass and wipe said windshield glass, the wiper blade comprising:
- a plurality of elastic members each attached integrally to a blade rubber contacting with said windshield glass and coupled in a longitudinal direction to be elastically deformable in a direction perpendicular to said windshield glass.
A manufacturing method of a wiper blade having a blade rubber contacting with a windshield glass and a rubber holder for holding said blade rubber and attached to a wiper arm swingably provided to a vehicle to wipe said windshield glass, the manufacturing method comprising:
- a sub-holder forming step of forming a plurality of sub-holders each having a holding portion holding said blade rubber and being elastically deformable in a direction perpendicular to said windshield glass;
- a sub-holder coupling step of coupling said plurality of sub-holders in the longitudinal direction to form said rubber holder;
- and
- a blade-rubber attaching step of attaching said blade rubber to said rubber holder.
