Patent attributes
The present invention maintains sealing of the housing over a long period of time. A multiple-optical-axis photoelectric sensor (100) includes a light projector (110) and a light receiver (120) whose external forms are each formed by a housing (1) including an outer case (10) constituted by a main body case (11) and a first cap member (12), a light-transmitting plate (15), a first pressing member (20A), second pressing members (20B), a first adhesive tape (17A), and second adhesive tapes (17B). The first cap member (12) has a supporting part (12a) provided on its inner side, and an elastic member (18) is provided between the second pressing member (20B) and a portion of the light-transmitting plate (15) supported by the supporting part (12a). The light-transmitting plate (15) is pressed toward the first cap member (12) via the elastic member (18).
