Abstract: A transmission case (10) includes a case (2) and a side cover (3). A rotation sensor (5) including a connector terminal part (52) is attached to the side cover (3). A seal member (FIPG) (4) is interposed between joining surfaces (22a, 32a) of the case (2) and the side cover (3). A notch portion (25) where the seal member (4) is accumulated is provided to an outer peripheral surface (22b) of the joining surface (22a) which is adjacent to the connector terminal part (52). Accordingly, the amount of the seal member (4) protruding outward from the outer peripheral surface (22b, 32b) of the flange portions (22, 32) is reduced, thus suppressing connection failure of a connector.

Abstract: A Fresnel lens sheet comprising a Fresnel lens substrate and a Fresnel lens, whose surface of the light source side has an average pitch of 200 ?m or smaller and ten point roughness of 3 to 15 ?m, a rear projection screen obtained by assembling the Fresnel lens sheet and a lenticular lens sheet, and a process for producing these. With the use of the Fresnel lens sheet and the rear projection screen in accordance with the present invention, a labyrinth light inside the screen and a surface reflection are diffused effectively and a ghost caused by them is remarkably reduced. Accordingly, the rear projection television employing the Fresnel lens sheet and the rear projection screen of the present invention provides excellent images without ghost light.
