Wiper for vehicle

A vehicle wiper comprising:

• a wiper arm;
• an arm side coupling portion arranged on a distal end of the wiper arm;
• a wiper blade;
• a blade side coupling portion arranged on the wiper blade and pivotally coupled to the arm side coupling portion;
• two side walls arranged on one of the arm side coupling portion and the blade side coupling portion, wherein the two side walls face each other;
• two support shafts that respectively project from inner side surfaces of the two side walls, wherein the two support shafts are coaxial with each other;
• and
• two shaft support recesses arranged on the other one of the arm side coupling portion and the blade side coupling portion, wherein the two support shafts are pivotally fitted to the two shaft support recesses, respectively,
• wherein:
• each of the support shafts has a small diameter portion located at a predetermined angular position of the wiper arm relative to the wiper blade, and the small diameter portion has a smaller radial dimension than the diameter of the support shaft;
• each of the shaft support recesses includes an attachment-separation port, and the attachment-separation port has a dimension that is smaller than the diameter of the support shaft and larger than the radial dimension of the small diameter portion;
• an attachable-separable region and a non-attachable-separable region are set as angular regions of the wiper blade relative to the wiper arm;
• when the wiper blade is in the attachable-separable region, the attachment-separation port and the small diameter portion of the support shaft are in correspondence with each other thereby enabling attachment and separation of the support shafts and the shaft support recesses;
• when the wiper blade is pivoted about the support shaft from the attachable-separable region to a wiper usage position and the wiper blade is in the non-attachable-separable region, the attachment-separation port and the small diameter portion are not in correspondence with each other thereby disabling attachment and separation of the support shafts and the shaft support recesses;
• and
• the arm side coupling portion or the blade side coupling portion that includes the shaft support recesses includes a shape sustaining portion that sustains the shape of the attachment-separation port, and the shape sustaining portion is located between the two shaft support recesses.
