Abstract: An electric lock device for an opening and closing member includes: a lock portion; a rod; a biasing member; and an actuator. The actuator includes a case, a motor, a wheel, and a rotor. The wheel is provided with a pressing portion that is configured to engage with a receiving portion provided on the rotor or the rod when the wheel rotates in a predetermined direction to move the rod. When a rotation force is applied to the rotor in a direction against a biasing force of the biasing member via the rod in a state where the rod is biased by the biasing member in a direction in which the rod is engaged with the lock portion, the rotor is capable of rotating independently of the wheel in a direction in which the receiving portion is separated from the pressing portion.

Abstract: There is provided a damper device including: a cylinder; a piston; and a seal ring. The piston includes: a column portion wound around the seal ring; and a first restricting portion and a second restricting portion that are configured to restrict movement of the seal ring in a axial direction. The column portion has a protruding portion protruding outward in a radial direction. The first restricting portion has a cutout portion. The seal ring is capable of taking a deformed state where the seal ring is deformed so as to partially enter the cutout portion by movement of the piston. In a case where the seal ring is in the deformed state, and in a normal state where the seal ring does not enter the cutout portion, the seal ring is pressed against an inner peripheral surface of the cylinder by the protruding portion.

Abstract: There is provided a locking device for an opening and closing body, including: a locking portion; a base; a rotation body that includes a protruding portion on a part of an outer periphery thereof; a locking member; and an elastic member that includes a base portion, and a stopper portion configured to restrict a maximum rotation position of the rotation body in a predetermined direction by abutting against the protruding portion of the rotation body. The stopper portion is disposed in a manner of being biased in a direction opposite to the predetermined direction relative to the base portion. A part of the outer periphery of the rotation body is provided with a sliding contact portion that is configured to come into sliding contact with the elastic member in a process in which the protruding portion approaches the stopper portion.

Abstract: There is provided a valve device, including: a housing; a float valve; and a seal member. An opening portion includes a first region, and a second region. The seal member includes a first cover portion, and a second cover portion. The second cover portion includes a support portion, a wide portion, and a narrow portion. In a state where the seal member is retained and supported by the support portion with respect to the float valve, a width of the wide portion is set such that a tip end of the second region is covered, and that the second region of the opening portion is not exposed out of the seal member even in a state where the seal member is maximally displaced in a radial direction and/or a peripheral direction of the housing with respect to the opening portion.

Abstract: There is provided a lock lever including: a base portion having an operation portion; a rotation shaft portion that is pivotally supported by the lid body and that allows the base portion to rotate; a lock portion that is configured to rotate together with the base portion and that is configured to be locked to or unlocked from the fixed body in accordance with rotation; and an elastic piece that extends from the base portion and that has a tip end side configured to elastically contact the lid body to bias the lock portion in a direction to lock the lock portion. The elastic piece extends from the base portion so as to approach the rotation shaft portion, and extends so as to be separated from the rotation shaft portion toward a tip end on the way when viewed in a rotation axis direction.

Abstract: A lock device includes a base member fixed on an opening/closing member, an operation member rotatably supported on the base member, and a rod configured to move forward and backward to be engaged with and disengaged from a locked portion of the fixed member in response to operation of the operation member. The operation member includes a pivot portion and a transmission portion. The base member includes a first attachment portion and a second attachment portion. When the transmission portion presses an inclined surface of the rod and thus causes the rod to move backward, the first attachment portion abuts against the rod, thereby limiting movement of the rod in the direction intersecting with the forward and backward movement direction of the rod.
