摘要：PURPOSE:To moderate a quick ret action of a spring by providing an air cylinder between an arm head and an arm piece in parallel with the spring, and increasing the passage resistance of the air cylinder at the reversal time of a wiper arm. CONSTITUTION:In a wiper arm, an air cylinder 11 is interpod between an arm head and an arm piece in parallel with a spring not shown in a figure. Each orifice 18, 19 having a large diameter and a small diameter and passing through from the inside to the outside of a cylinder chamber 16 is respectively opened in a piston part 14 of the air cylinder 11, and while a lead valve 21 is attached to the orifice 18 having the large diameter, freely to be opened and clod. At the reversal time of the wiper arm, the air cylinder 11 is com presd. Namely, the cylinder chamber 18 is compresd to clo the orifice 18 having the large diameter with the lead valve 21. The passage resistance is thereby incread to moderate the ret action of the spring and eliminate the generation of large noi.
