Abstract: A rotary connector device includes a stator, a rotator, a first connector, and a second connector. The stator is configured to be attached to a vehicle body. The rotator is provided rotatably about a rotation axis with respect to the stator. The first connector is provided at the stator. The second connector is provided at the rotator. The first connector includes a first connector housing space in which a vehicle-body-side connector is disposed in a state where the vehicle-body-side connector is electrically connected to the first connector. When viewed from an axial direction defined along the rotation axis in a state where the stator is attached to the vehicle body, the first connector housing space is disposed not to overlap a vertical plane including the rotation axis.

Abstract: An optical connection component includes an optical fiber; a high relative refractive-index difference optical fiber that is fusion-spliced to the optical fiber and has a greater relative refractive-index difference to a cladding of a core than the optical fiber; and an accommodating member accommodating the entire length of the optical fiber and the high relative refractive-index difference optical fiber, and has a first end face on which an end face of the optical fiber on the side opposite to the fusion-spliced side is exposed to be substantially flush with the first end face, and a second end face on which an end face of the high relative refractive-index difference optical fiber on the side opposite to the fusion-spliced side is exposed to be substantially flush with the second end face. The optical fiber and the high relative refractive-index difference optical fiber are fixed to the accommodating member.

Abstract: Provided are a joining structure, a joining method, an exterior body for a wire harness, and a wire harness capable of firmly joining members having different physical properties while reducing the thickness of a joint part. The joining structure 10 joins a first member 1 made of a first resin and a second member 2 made of a second resin, wherein: the second resin has physical properties having a higher foaming ratio than the first resin; and a recessed joint part 3 is provided which reaches at least the inside of the first member 1 from the outer surface side of the second member in a state in which the first member 1 and the second member 2 are superimposed. Furthermore, a method for manufacturing the joining structure 10 comprises the steps of: superimposing a first member 1 made of a first resin and a second member 2 made of a second resin having physical properties having a higher foaming ratio than the first resin; and joining the first member 1 and the second member 2 by forming the recessed joint part 3 by pressing and hot-melting the second member 2 until the recessed joint part 3 reaches at least the inside of the first member 1 from the outer surface side of the second member 2.

Abstract: A cancel cam includes an annular member, a cam wall, and at least one reinforcing rib. The annular member is rotatable integrally with a steering shaft about a rotation axis and includes an outer peripheral portion, an inner peripheral portion, and a first surface. The cam wall extends from the outer peripheral portion in an axial direction and extends along the outer peripheral portion in a circumferential direction. The at least one reinforcing rib extends from the cam wall toward the inner peripheral portion and couples the cam wall to the annular member. The cam wall has a first axial length defined from the first surface in the axial direction. The inner peripheral portion has a second axial length defined from the first surface in the axial direction. The second axial length is shorter than the first axial length.
