摘要： One object of the present invention is to provide a power transmitting apparatus which can reduce the gear shifting time lag and thus improve the power transmitting efficiency as well as can easily mount the sealing member to the outer circumference of the input shaft and thus reduce the manufacturing cost of the power transmitting apparatus. According to the present invention there is provided a power transmitting apparatus characterized in that the gear-stage clutch means comprises alternately arranged driving clutch discs and driven clutch discs; a hydraulic piston actuated by hydraulic pressure to selectively engage or disengage the driving clutch discs and driven clutch discs; hydraulic chambers for actuating the hydraulic piston; and hydraulic oil supplying ports communicating with oil passages formed within the input shaft and opening on the side surface of the input shaft for supplying the hydraulic chambers with hydraulic oil from the oil passages to actuate the hydraulic piston; that the power can be transmitted at a predetermined gear ratio with engaging the driving clutch discs with driven clutch discs of the gear-stage clutch means by selectively supplying the hydraulic chambers with hydraulic oil; and that an annular sealing member is fitted in a recessed portion formed around each opening of the hydraulic oil supplying port opened on the outer circumference of the input shaft and the recessed portion has a flattened bottom surface on which the sealing member is seated so that it is contacted with the flattened bottom surface of the recessed portion.
