    • An oil filter has a drain hole, which is internally blocked with a valve member. When oil remaining in the oil filter is drained, a drainpipe is inserted into the drain hole, so that the valve member is displaced and remaining oil is drained from the drain hole. This valve member has an annular recession to steadily support an upper end of the inserted drainpipe. Therefore, gripping force of the drainpipe is enhanced without decreasing draining performance. The drainpipe and the oil filter are connected with each other via a seal member that is provided to the oil filter. The drainpipe 80 has a removing means that holds at least a part of the seal member to pick the seal member off the oil filter, when the inserted drainpipe is detached from the drain hole. Thus, the seal member can be removed simultaneously with the drainpipe from the oil filter.
    • 油过滤器具有排水孔,其内部被阀构件封闭。 当油滤清器中残留的油被排出时,将排水管插入到排水孔中,使得阀构件移位,剩余的油从排水孔排出。 该阀构件具有环形凹部以稳定地支撑插入的排水管的上端。 因此,排水管的夹持力增强而不降低排水性能。 排水管和油过滤器通过设置在油过滤器上的密封构件相互连接。 排水管80具有除去装置,当从插入孔分离插入的排水管时,保持至少一部分密封构件以将密封构件从油过滤器上取出。 因此,密封构件可以与排油管同时从油过滤器去除。
