A step hinge for a PDA which is rotated to various angles is provided to be mounted to the personal portable terminal and to be freely set at various angles. A rotating member(200) is mounted on a housing and rotates. A friction member(300) contacts a rotating member and is mounted inside the housing. Two belleville springs(400) are mounted on the inside of the housing and pressurizes so that the friction member and rotating member adhere closely. The two belleville springs having great diameter are mutually faces with each other. The two belleville springs having small diameter are mutually contacts to the friction members.
