Abstract: According to the present invention, a cylindrical battery comprises: an electrode assembly in which a long negative electrode, having a core body exposed section in which a negative electrode core body is exposed on one side in the width direction thereof, and a long positive electrode are wound with a separator therebetween; and a lower current collector which has a flat part that axially overlaps a central portion of a hollow section of the electrode assembly and does not have a through-bole, a protruding bead part to which the core body exposed section is joined, and one or more through-holes positioned on a further outer circumferential side in the radial direction than the flat part and further inside in the radial direction than the protruding bead part.

Abstract: A handle switch device that prevents a user from being bothered when supplying power, and enables a user to easily check a connection state of a power cord. A handle switch device 10 to be attached to a handlebar 11 of a vehicle 21 is provided with a USB port 18 for supplying power to an external device, and the USB port 18 is directed inwardly with respect to a width direction of a vehicle 21 in a state in which the handle switch device 10 is attached to the handlebar 11.

Abstract: A handle switch device capable of supplying electric power to an external device without damaging electronic components. A handle switch device 10 comprises a main substrate 20, on which electronic components are disposed, a USB substrate 19, on which a USB port 18 for supplying electric power to an external device is disposed, and a switch housing 12 that houses the main substrate 20 and the USB substrate 19. The main substrate 20 and the USB substrate 19 are disposed so as to be separated from each other.

Abstract: A handle switch device capable of preventing damage to a connection terminal. A handle switch device 10 mounted on a handlebar 11 of a vehicle 22 comprises a case-shaped switch housing 12 and a USB port 18 that supplies electric power to an external device. The USB port 18 is covered with an inner case 19 inside of the switch housing 12. The inner case 19 has a tubular opening 19a. The USB port 18 communicates with outside of the switch housing 12 through the opening 19a, and the USB port 18 is disposed on an inner side of the switch housing 12 rather than the opening 19a.

Abstract: A manifold for a body support apparatus is disposed in a frame together with an air source. This manifold for a body support apparatus includes: a first opening through which air from the air source is supplied; multiple second openings which are connected to openings of the frame; a space which communicates with the first opening; and multiple flow passages which connect the space and the multiple second openings to each other and are designed to open and close. The inside of this manifold for a body support apparatus is sealed.

Abstract: A sealed cell includes a bottomed cylindrical outer casing can. The outer casing can is formed by nickel-plated iron, and a lead connected to one of a positive electrode and a negative electrode, and the outer casing can, are welded by a welding part formed from the outside surface of the outer casing can toward the lead. The welding part is formed by molten traces and has a first layer and a second layer having a higher nickel concentration than the first layer. The first layer is formed from the lead through to the inside of the outer casing can, the second layer is formed so as to adjoin the first layer on the outside surface side of the outer casing can, and the whole of the first layer is covered with the second layer when the welding part is viewed from the outside of the outer casing can.
