This vertical-sliding-type manually opened/closed door (10) exhibiting excellent one-handed operability is provided with: a plate-shaped door member (13) which slides in the vertical direction to open and close an opening; support members (11, 12) in which sliding of the door member (13) in the vertical direction is guided by support parts (42) for supporting left and right ends of the door member (13); and a lock mechanism for positioning the raised door member (13). The lock mechanism is provided with a lock member (17) which is attached to the outside surface of the door member (13), and which receives an impelling force from an impelling member (35) in the outward direction. Engagement parts (171), which are pressed against the support members (12) in the outward direction by the impelling force of the impelling member (35), are formed on the lock member (17). Receiving parts (18), which are configured such that the engagement parts (171) of the lock member deviate from the support parts (42) in the outward direction, and enter the receiving parts (18), are formed on the support members (12). |
