Abstract: A profile radius change rate, which is an amount of change in a profile radius of a drive cam relative to a rotational angle of the drive cam in a pocket boundary section located between a progressively changing portion and a pocket portion, is set such that a boundary sound pressure, which is a sound pressure generated when a contact point between a roller and the drive cam passes through the pocket boundary section in response to the rotational movement of the drive cam, is included in a reference sound pressure range, which is a range of variation in a sound pressure generated when the contact point passes through the progressively changing portion.

Abstract: A drive cam is rotated about a camshaft member upon application a drive torque of a drive source to the drive cam. A transmission device converts rotational motion of the drive cam into linear reciprocating motion and transmits the converted linear reciprocating motion to a control shaft member. The control shaft member is connected to a controlled subject and is linearly reciprocated together with the transmission device in an axial direction. A reverse input cutoff clutch transmits the drive torque, which is received from the drive source, to the drive cam. The reverse input cutoff clutch non-rotatably locks an output shaft of the drive source in response to a reverser input torque transmitted from the controlled subject through the drive cam.

Abstract: A driving device has a driving cam driven by a motor around a cam shaft, a roller which is in contact with the driving cam, a supporting frame, and a control shaft. The driving cam has a pocket portion. At the pocket portion, a profile distance from a center increases or decreases when the driving cam rotates in a normal direction or a reverse direction. When the pocket portion is in contact with the roller and the motor is stopped, the rotational force of the driving cam becomes zero. The rotational position of the driving cam and the axial position of the control shaft are held at a constant position. Thereby, the rotary place of the driving cam and the axial position of the control shaft component can be held in a fixed position.

Abstract: A fluid filter includes a case in which an inflow path, an outflow path, and a drainage path are formed, a cap which is engaged with the case through axial rotation, a biasing device (a coil spring) which biases a filter element housed inside a casing constituted by the case and the cap toward the case side, a rotation restricting device (an abutting portion and a projecting portion) which restricts rotation of the filter element in a fastening direction when the cap is rotated relative to the case in the fastening direction, and a sealing member provided on an axial end surface side of the filter element, which seals the drainage path when the filter element is biased by the biasing device and rotation thereof is restricted by the rotation restricting device.

Abstract: A bubble separator includes a body with a generally cylindrical shape, an oil induction portion, a gas discharge portion with a generally cylindrical shape, an oil discharge portion, and an upper partition. The oil induction portion is provided on the body, and introduces bubble-containing oil to inside the body. The gas discharge portion is provided extending from a ceiling portion of the body, and discharges separated bubbles to outside the body. The oil discharge portion is provided on the body, and discharges separated oil to outside the body. The upper partition is provided extending from the ceiling portion, and is formed on a periphery of the gas discharge portion. According to the bubble separator of the present invention, the upper partition can prevent bubble-containing oil from directly blowing into the discharge hole of the gas discharge portion and discharging to outside the body together with separated gas.

The leaf spring member has a free end side that is provided with a contact portion, which contacts the regulating portion due to relative rotation of the first casing member and the second casing member.

Abstract: The invention provides a drain mechanism of a fluid filter in which a heated fluid is not splashed on a worker at a time of discharging the fluid such as a time of exchanging an element, and can inhibit dusts or the like from being mixed from an external portion at a time of normal use.

Abstract: A drain structure for a fluid filter includes a cap internally forming a drain hole. The cap receives a valve member urged by an urging means in a direction, in which the valve member blocks the drain hole. Normally, the drain hole is blocked with a drain member. When fluid is drained from the drain hole, the drain member is removed from the drain hole, and a drain tool is inserted into the drain hole, so that the drain tool displaces the valve member in a direction, in which the drain hole is unblocked. The drain tool has a hooking portion that can hook to a hooked portion provided to the cap by axially rotating the drain tool inserted into the drain hole of the cap. Thus, the drain tool can be connected with the cap while the hooking portion is supported by the hooked portion.

Abstract: 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.
