PROBLEM TO BE SOLVED: To provide a sash roller capable of supporting a wheel so as to tilt freely and adjust a height freely and reducing the number of parts and having a simple structure. SOLUTION: A movable frame 10 is assembled in a fixed frame 1 having a pair of side plates to support it so as to oscillate freely in the vertical direction. An adjusting screw 8 which presses the movable frame 10 and oscillates it downward is screw-engaged with the fixed frame 1. A shaft insertion hole long in the vertical direction is provided in a tip part of a pair of side plates of the movable frame 10, and a wheel 20 is supported by an axle 21 inserted into the shaft insertion hole to tilt the wheel 20 freely. An elastic piece which is pressed by an end part of the axle 21 and is elastically deformed in outward direction due to the inclination of the axle 21 is provided in the fixed frame 1, and both ends of the axle 21 are pressed due to restoration elasticity of the elastic piece to return the axle 21 to a horizontal condition so that a necessity of assembling of a spring is eliminated, the number of parts is reduced, and manufacturing cost is reduced.
