Abstract: Provided is a gas sensor that prevents a ceramic housing from biting into a member arranged on a rear end side of the ceramic housing in a state of being inclined from an axial direction. In the gas sensor according to one aspect of the present invention, a spacer having Young's modulus of 80 GPa or more is arranged at least in a front end portion on a rear end side of the ceramic housing to which a terminal fitting is attached.

Abstract: A saddle riding vehicle includes a unit swing engine swingably supported on a body frame through a link member, and an exhaust device provided with an exhaust pipe and a catalyst device. The link member is disposed on an upper side of a crankcase. Part of the catalyst device is disposed below a cylinder section and is located in a region between an imaginary line that connects a link member coupling section coupling the link member to the body frame and a front end of the crankcase and an imaginary line that connects an exhaust pipe connection section of the unit swing engine connected with an end of the exhaust pipe and the link member coupling section, in side view. An exhaust device coupling section that couples the crankcase and the exhaust device is provided.

Abstract: The cage for breeding small animals according to the present invention comprises a casing with an opening on an upper surface thereof, and a lid for covering the opening of the casing. The lid comprises a frame body attached to an upper end edge of the casing, and an opening for a water supply apparatus to which the water supply apparatus is attached in an openable and closable fashion. A partition board is placed in the casing to divide the housing section within the casing into two. A ventilation section is provided in the partition board, for ventilation between one room and the other room of the divided housing section in the casing. A communicating section for placing a tip of a nozzle of the water supply apparatus is provided by cutting out the partition board.
