A wiper blade extends in the longitudinal direction and includes blade rubber, a plate spring-like backing, and a rubber holder. The blade rubber wipes a surface to be wiped. The backing imparts rigidity and elasticity to the blade rubber. The rubber holder holds both the longitudinally intermediate section of the blade rubber and the longitudinally intermediate section of the backing. The rubber holder has a backing housing hole for housing and retaining the backing. The backing housing hole longitudinally extends through the rubber holder. A parting line is set at the longitudinal center of the backing housing hole.

Wiper blade and method for manufacturing wiper blade

A wiper blade extends in a longitudinal direction and includes a blade rubber, a plate spring-like backing, and a rubber holder. The blade rubber wipes a wiped surface. The backing adds rigidity and elasticity to the blade rubber. The rubber holder holds an intermediate portion of the blade rubber in the longitudinal direction and an intermediate portion of the backing in the longitudinal direction. The rubber holder includes a backing accommodation slot that accommodates and holds the backing. The backing accommodation slot extends through the rubber holder in the longitudinal direction. The parting line is set in a middle section of the backing accommodation slot in the longitudinal direction.

A wiper blade includes a wiper strip, a backing, a blade holder coupled to the wiper arm, and two opposed cases arranged at two longitudinal ends of the blade holder. The blade holder includes a blade holding portion, which surrounds a base portion of the wiper strip and the backing at a longitudinally central portion of the wiper strip and the backing. The blade holding portion restricts movement of the wiper strip and the backing in a direction orthogonal to the longitudinal direction. Each case includes a case holding portion that surrounds the base portion of the wiper strip and the backing. The case holding portion restricts movement of the wiper strip and the backing in a direction orthogonal to the longitudinal direction.

Wiper blade and wiper for vehicle

A wiper for a vehicle includes an elongated wiper strip, a backing extending in the longitudinal direction of the wiper strip, and a blade holder for holding the wiper strip and the backing. The blade holder includes a pair of side surfaces that face in opposite directions. The wiper also includes a coupling member and a wiper arm. The coupling member has a pair of side walls, which face the corresponding side surfaces, and is attached to the blade holder. The wiper arm has a distal coupling portion attached to the coupling member. When the distal coupling portion is attached to the coupling member, side cover walls of the distal coupling portion are each engaged with the corresponding side wall of the coupling member.

Vehicle wiper

A wiper blade includes a wiper strip having an elongated retained portion, a backing, and a case, which retains therein the retained portion and the backing. The cap is attached to at least one of the ends in the longitudinal direction of the backing or to at least one of the ends in the longitudinal direction of the case. The interior space of the cap communicates with the interior space of the case. The cap has a rubber insertion hole that opens to the outside of the cap. The retained portion can enter the interior of the cap via the rubber insertion hole.
