Abstract: An overturn-notification-rider-informing-device includes: an acquisition section that acquires notification preparation information indicating that a leaning-vehicle-overturn-notification-system is preparing to notify of overturn occurrence information to outside of the leaning vehicle, or notification completed information indicating that the leaning-vehicle-overturn-notification-system has notified of the overturn occurrence information to outside of the leaning vehicle; and an actuation section that, based on the notification preparation information or the notification completed information, causes light to be radiated or sound to be generated by actuating at least one component among a front light and the like in an operating state that is different from an operating state of the relevant component at a time when, or immediately before, the leaning vehicle changes from a travelling state to an overturned state, and thereby informs of the overturn notification state to the rider.

Abstract: A leaning vehicle includes a cancel switch for cancelling notification of overturn occurrence information. A handle includes one or more right switch boxes to the left of a right handle grip, and one or more left switch boxes to the right of a left handle grip. The cancel switch is a position that is within a center region located between a plane perpendicular to the left-right direction that includes the left end of a right switch box which is furthest to the left among the one or more right switch boxes, and a plane perpendicular to the left-right direction that includes the right end of a left switch box which is furthest to the right among the one or more left switch boxes. The cancel switch is at a position that is visible in one or more horizontal directions in the leaning vehicle in an overturned state.

Abstract: An open-cabin vehicle is provided that makes it possible to enjoy the convenience provided by electronic devices while suppressing electric power consumption and also suppressing a reduction in the convenience of the open-cabin vehicle. An identification signal transmission unit inside an electric power control apparatus of an open-cabin vehicle intermittently transmits an identification signal (ID). A response signal reception unit receives a response signal (RE) that is transmitted from a portable terminal in response to the identification signal (ID) without any operation by a rider on the portable terminal or the open-cabin vehicle. When the response signal reception unit receives the response signal (RE), a command unit commands current conduction in a first electric power supply circuit and does not command current conduction in a second electric power supply circuit.

Abstract: A rotary cylinder apparatus which prevents a fluid from leaking from a contact portion of a piston and a cylinder member and consequently enables efficient rotation. The rotary cylinder apparatus comprises: a rotary cylinder member 2 which has cylinder chambers 22 and 23 formed thereto so as to pass through a rotary shaft center O and rotates around the rotary shaft center O; pistons 3 and 4 demonstrating reciprocating linear motion in the cylinder chambers 22 and 23; a piston holding member 5 which holds the pistons 3 and 4 and rotates around a rotation center X eccentric from the rotary shaft center O of the rotary cylinder member 2; and a casing 6 which rotatably supports the rotary cylinder member 2 and has at least one inlet 61 and at least one outlet 62, wherein the pistons 3 and 4 are rotatably supported at a position away from the rotation center X of the piston holding member 5 by a fixed distance and with that position at the center thereof.
