Blade rubber regeneration device, blade rubber regeneration method, and regenerated blade rubber manufacturing method

A blade rubber regeneration device, the blade rubber being provided on a wiper blade used for a wiper device of a windshield of a vehicle, wherein

• the wiper blade comprises the blade rubber and a blade stay supporting the blade rubber,
• the blade rubber has a base part, which is an attaching part of attaching the blade rubber to the blade stay, a lip portion, and a neck portion swingably connecting the lip portion to the base part,
• at least a part of a tip end of the lip portion constitutes a contact part contacting with the windshield,
• the regeneration device comprises a blade portion for cutting off the tip end of the lip portion in a longitudinal direction of the blade rubber,
• the regeneration device cuts off a part of the tip end of the lip portion by causing the blade portion to enter the lip portion from a side portion of the tip end of the lip portion at an end part A, which is one end part in the longitudinal direction of the blade rubber, and to relatively move toward an end part B, which is the other end part in the longitudinal direction,
• the regeneration device comprises:
• a sandwiching member of sandwiching the lip portion;
• an urging member which is brought into contact with the end part B of the lip portion and urges the lip portion to a direction of the end part A;
• and
• a pressing member which presses the tip end of the lip portions toward the base part,
• the sandwiching member sandwiches at least a part of the lip portion from both side portions of the lip portion on a cross-sectional view in a direction orthogonal to the longitudinal direction of the blade rubber,
• the sandwiching member is disposed at a position capable of sandwiching at least a part into which the blade portion of the lip portion enters, and a position of the sandwiching member with respect to the blade rubber is fixed, and
• the pressing member presses the tip end of the lip portion toward the base part prior to relative movement of the blade portion from the end part A to the end part B.
