Abstract
There is disclosed a sliding member which slidably contacts an counterpart member with friction and in which a friction force is varied without changing a contact pressure. A sliding member is formed by covering a steel plate with sliding materials to different in friction coefficient. In this case, when a sliding direction of the counterpart member is set to directions of arrows A and B, a sliding material of a low friction coefficient is disposed in the middle, and the sliding materials to are arranged so that the friction coefficient gradually increases toward both terminal sides in the directions of arrows A and B of the sliding material . According to the sliding member , the friction force increases as the counterpart member moves in the directions of arrows A and B from the middle.
