PURPOSE: To obtain a cap for a replenishing port for a replenishing liquid capable of surely preventing the splashing of the replenishing liquid and the intrusion of other replenishing liquids and filling the replenishing liquid into the replenishing port without degrading the workability thereof at the time of such filling. CONSTITUTION: The cap 114 for opening and closing the replenishing port 108, etc., is composed of a main body part 116 and a pair of side wall parts 118 formed integrally at both ends of this main body part 116. The replenishing port 108 is held in the state that its circumferential edge part is enclosed to a U shape in plain view when the cap 114 is in the state of opening the replenishing port 108. Then, the splashing of the replenishing liquid 18 prevented by the cover 114 even if the liquid tends to splash to the periphery. The intrusion of the other replenishing liquid into the adjacent replenishing ports does not arise. There is no need for excessively and prudently executing the filling operation and the degradation of the filling workability does not arise. |
