The wiper device 40 includes a wiper arm 61 which is fixed to a pivot shaft 42 and supports a wiper blade 51. The wiper arm 61 is formed by a plate spring member which biases a tip part to a window panel 34. A lock back plate spring part 71, which is bent in a direction away from the window panel 34 more than the wiper arm 61, is provided at the wiper arm 61. A spring constant of the lock back plate spring part 71 is smaller than a spring constant of the wiper arm 61. |
