摘要： An electric actuator of the disclosure includes a motor, a speed reduction mechanism, and a bearing fixed to a motor shaft having an eccentric axis portion. The speed reduction mechanism has: an externally toothed gear, an internally toothed gear, a facing member facing the externally toothed gear, column members protruding from one member of the facing member and the externally toothed gear toward the other member and surrounding the motor axis, and at least one tube member surrounding the column members. The other member has hole portions surrounding the motor axis. The column members are inserted into the hole portions respectively, and support the externally toothed gear to be swingable around the motor axis via an inner side surface of each of the hole portions. The at least one tube member surrounds the column members in the hole portions and is rotatable around a rotary axis passing through the hole portions.

摘要： A pressure control device is provided and includes a body which has a groove-shaped flow path including a groove part and a widened part connected to the groove part and having a width larger than a width of the groove part, and a filter unit which captures foreign matters mixed in a fluid which passes through the groove-shaped flow path. The filter unit includes a frame body being in a cylindrical shape and including a through hole part which penetrates in a direction along a central axis, and at least one filter member being in a planar plate shape disposed to intercept the through hole part and supported inside the frame body, in which the filter unit is accommodated in the widened part so that a direction orthogonal to the central axis of the frame body is along a depth direction of the widened part.

摘要： In an oil-pressure-sensor attachment structure according to an aspect of the invention, an oil channel body includes a lower body and an upper body arranged at an upper side of the lower body in a superposed manner. The attachment structure includes the upper body, a sensor case, and a connection member including an electrical connection portion that electrically connects an external power supply with a sensor main body. The connection member contacts the upper body from the upper side. The upper body has a through hole in an up-down direction. The sensor case includes a columnar portion that extends in the up-down direction and is inserted into the through hole, a flange portion that protrudes outward in the radial direction from the columnar portion and is arranged to face the lower side of the upper body, and a first hook portion that is hooked to the connection member.

摘要： A guide protrusion includes first walls protruding upwards from an upper face of a body, facing each other across an opening in a first direction, and first protrusions protruding from each first wall toward the other. A receptive portion between the first walls has a first opening, opening to one side in a second direction orthogonal to the first direction. The sensor case is received from the first opening following the second direction. The guide protrusion has a first movement restricting face facing another side in the second direction. The sensor case includes a columnar portion extending vertically through a gap between the first protrusions, a flange at least partially between the upper face and the first protrusions in the vertical direction, within the receptive portion, and a facing portion on the other side of the first movement restricting face in the second direction, facing the first movement restricting face.
