PPROBLEM TO BE SOLVED: To easily and simply adjust an ear-piece member and a nose-piece member for wearing a subjective optometry device body on a subject. PSOLUTION: A support rod 17a for supporting the nose-piece member 17 is passed through the horizontal frame 19 of the subjective optometry device body 10 and its internal cylinder 20. In the state that the internal cylinder 20 is energized by a spring 20a. a piece of rubber 20f arranged in the through-hole 20c of the internal cylinder 20 is made abut on the peripheral surface of the support rod 17a, then the support rod 17a is made in a lock state. When a press button 20b is pushed-in against the energizing force, the internal cylinder 20 is displaced, then the rubber 20f is separated from the peripheral surface of the support rod 17a to release the lock state, thereby the nose part member 17 is made displacable.
