PURPOSE: To provide an inspection mirror capable of easily inspecting the narrow region of the space of machinery and hard to destruct. CONSTITUTION: This inspection mirror consists of two mirror plate materials 2, 3 different in length and these plate materials are connected in a freely stoppable manner by the hinge 8 fixed to the rear surfaces 6, 7 of the plate materials 2, 3 along the short sides thereof. By this hinge connection, one mirror plate material can be revolved with respect to the other mirror plate material within the range of about 270 deg. from a position where the mirror surfaces 4, 5 of the plate materials 2, 3 are mutually opposed at an almost right angle to a position where the rear surfaces 6, 7 are mutually overlapped. Each of the mirror plate materials 2, 3 is obtained by forming an aluminum layer 22 being a reflecting layer on one surface of a transparent plate 21 composed of an acrylic resin by vacuum vapor deposition and bonding a back plate 24 composed of soft polyvinyl chloride or synthetic rubber to the plate 21 by an adhesive layer 23 so as to cover the aluminum layer 22. |
