  • Patent number: 10763646
    Abstract: A spark plug having a metal shell and an insulator, wherein a stepped portion that includes a rear-end-side facing surface that retains an insulator either directly or via another member is provided at an inner periphery of a metal shell. The stepped portion includes a first convex portion that includes the rear-end-side facing surface, a second convex portion that is disposed on a front end side of the first convex portion and that is adjacent to the first convex portion, and a connection portion that connects the first convex portion and the second convex portion to each other.

  • Patent number: 10663076
    Abstract: A rotation stop shape is visually recognizable through an exposing hole. A relative angle between an output shaft and an actuator lever can be freely set while the rotation stop shape, which is visually recognizable through the exposing hole, is used as the reference angle of the output shaft. Therefore, it is possible to limit disadvantageous variations in a fixation angle of the actuator lever. The fixation angle of the actuator lever relative to the output shaft can be freely changed by using the rotation stop shape, which is visually recognizable through the exposing hole, as a reference angle of the output shaft.

  • Patent number: 10591079
    Abstract: A housing includes an opening portion, which opens in one direction. At the time of assembling, the opening portion of the housing is placed to face an upper side. Then, a wave washer, an electric motor and screws for motor fixation are assembled from the upper side, and a first intermediate shaft and a second intermediate shaft are press-fitted, and a lower bearing, an output shaft, a second intermediate gear, a first intermediate gear are assembled. Thereafter, a cover is installed from the upper side to the housing. Next, an actuator lever is connected to a distal end part of the output shaft. As discussed above, the electric actuator can be assembled without inverting an orientation of the housing, and thereby productivity can be improved.

  • Patent number: 10451154
    Abstract: Positioning of a cover relative to a housing is made at two locations. i.e., fitting between a first intermediate shaft and a first recess and fitting between a second intermediate shaft and a second recess. In this way, a load of the cover is not conducted to an output shaft through a cover-side bearing. Therefore, in a state where the cover is fixed to the housing, an excessively large load is not generated between a cover-side bearing and the output shaft and a housing-side bearing and the output shaft.

  • Patent number: 10389204
    Abstract: A plurality of reinforcing ribs, which extend from a cover-side bearing in an outer radial direction, is formed at a portion of a cover, at which a reaction force generated in response to operation of an electric actuator is applied. The reinforcing ribs can improve strength of the portion of the cover, at which the reaction force is applied. Therefore, it is possible to avoid a damage, such as deformation, a crack, at the resin cover caused by the reaction force applied to the cover.
