<p>A hand-feld remote control housing (1) comprises a roller (7) to be manipulated by a finger. A movable bearing member (8) has a receiving portion (8a) to support a rotary shaft (7a) of the roller (7) and a pressing portion (8c) held in abutment against a push button switch (10). The bearing member (8) is angularly movable with respect to the case 1, around the axis of subs (8b). The axis of stubs (8b) and the axis of the rotary shaft (7a) are offset from each other. The rotary shaft (7a) and a rotary shaft (5a) of an encoder (5) are provided with respective pulleys (11,12) which are coupled to each other using a belt (13). In order to prevent water that can enter the housing (1) via the roller (7) to cause short circuits, the roller (7) is surrounded by a water receiving member (14) comprising a drainage passage (14b). <IMAGE></p> |
