摘要： Disclosed is a subjective optometric apparatus in which the earpiece members and the nose pad member for attaching the main body of the device to the subject can be easily adjusted without involving any effort. The subjective optometric apparatus has a horizontal frame and an inner tube inserted into the horizontal frame, with a support bar for supporting a nose pad member being passed through the horizontal frame and the inner tube. In a state in which the inner tube is being biased by a spring, a rubber member provided in a through-hole of the inner tube abuts the peripheral surface of the support bar to lock the support bar, thereby bringing the nose pad member into a locked state. Further, when a push-button is pushed in against the biasing force of the spring, the inner tube is displaced and the rubber member is detached from the peripheral surface of the support bar, with the result that the nose pad member is released from the locked state and becomes capable of being displaced.
