To provide a movable plate for a snow slider which is moved to naturally bend the plate at a fixed position of an attachment of a binding or the like.

The movable plate 1 includes: a board 2 for fixing the fixed plate 28 of the binding; and mobile portions 9, 10 arranged on the rear surface side of the board 2. The mobile portions 9, 10 include: turning ends 15, 16 to be turned in the front and rear directions of the board 2; and axial bodies 13, 14 for supporting the turning ends 15, 16. A snow board 25 is fixed to the turning ends 15, 16. When the snow board 25 is flexibly bent in turning, the turning ends 15, 16 are turned in a rear direction by following the bending in the movable plate 1. Thus, the snow board 25 is not inhibited in bending, so as to attain sliding in a naturally bent and stable state.
