WIPER ARM

摘要

PROBLEM TO BE SOLVED: To provide a wiper arm capable of improving the workability of securing a base end of the wiper arm into a pivot shaft. SOLUTION: A hinge hole 63 is depressed in an arm head 55 in the crosswise direction, and a hinge projection 64 is projected in an inner wall of a cap 61 toward the inside from the both wall faces. The arm head 55 and the cap 61 are hinge-connected with the hinge hole 63 and the hinge projection 64. A revolving band 65 is formed in a recess part expanding from the hinge hole 63 toward the axial direction. A projection part 64a expanding toward the axial direction of the hinge projection 64 is formed, and the projection part 64a is stored in the revolving band 65. A stopping projection part 66 projecting toward the inside of the revolving band 65 is provided in the revolving band 65 so that the distance from an opening restricting end 65a is made almost the same as the width of the stopping projection part 66.
