Abstract: A fuel tank structure of a straddle vehicle includes a fuel tank which accumulates fuel supplied from a fuel filler port, a fuel tray which is provided above the fuel tank so as to surround the fuel filler port, and a gas-liquid separator which is connected to the fuel tank and separates the fuel into gas and liquid. The gas-liquid separator is spaced apart from the fuel tank and provided on the fuel tray.

Abstract: A straddle vehicle includes: a body frame including a main frame extending rear-downward from a head pipe, a pivot frame extending downward from the main frame, and a lower frame which extends downward from the head pipe and extends rearward, and further, is connected to a lower portion of the pivot frame; a side stand which supports a vehicle body during parking; and a main step on which a foot of a rider is placed. A side stand bracket for supporting the side stand includes a first fixing portion connected only to the lower portion of the pivot frame and a second fixing portion connected only to a main step bracket for supporting the main step.

Abstract: In an air cleaner for a vehicle, a connection part of a first intake duct to a cleaner case is disposed in a front half portion of one of left and right half portions of the cleaner case, the first intake duct including a first air inlet port opening forward. A connection part of a second intake duct to the cleaner case is disposed in a rear half portion of an other of the left and right half portions, the second intake duct including a second air inlet port opening rearward. The first intake duct is formed to include a first air outlet port opening rearward inside an unpurified chamber and curve in an up-down direction in a side view, and the second intake duct is formed to include a second air outlet port opening forward inside the unpurified chamber and curve in a right-left direction in a plan view.

Abstract: A parking brake attachment structure is provided secured to a separate portion of the vehicle frame disposed above the main frame section. The attachment structure includes a bracket secured above the vehicle to the auxiliary frame. A stay is mounted so as to protrude rightwardly from the bracket. A lever support bracket is mounted to the stay, inclined at an angle from the vertical. A parking brake lever mechanism including a lever pin, a parking brake lever, and a spring, is provided in the lever support bracket such that the parking brake lever is inclined at angle from the vertical. The parking brake lever is offset from a vehicle centerline. This mounting configuration requires only a small space around a parking brake lever, and enhances operability and the operating feel of the parking brake.

Abstract: A structure is provided for installing in a motorcycle an anti-theft device capable of reporting its position by wirelessly transmitting at least identifying information utilizing the GPS or PHS positioning system. The structure includes a receptacle and an openable cover that can be locked to secure the receptacle, and the anti-theft device is installed in the receptacle. The receptacle can be a helmet box formed in the motorcycle and a cover that can be an openable and lockable motorcycle seat. The structure conceals the anti-theft device, protects it from vibration and invasion of rainwater, and can include a case with enhanced waterproofing capability in which the anti-theft device is accommodated so that an indicator thereof is visible through a transparent window.

The structure includes a receptacle and an openable cover that can be locked to secure the receptacle, and the anti-theft device is installed in the receptacle. The receptacle can be a helmet box formed in the motor cycle and cover the can be an openable and lockable motorcycle seat. The structure conceals the anti-theft device, protects it from vibration and invasion of rainwater, and can include a case with enhanced waterproofing capability in which the anti-theft device is accommodated so that an indicator thereof is visible through a transparent window.

Abstract: A leaf spring includes a plate having a hole into which a key cylinder is inserted, a notch into which a convex portion of the key cylinder is inserted, and spring tabs which can be bent elastically in the insertion direction of the key cylinder formed thereon. The top end of the spring tabs is inclined with respect to the bottom of the rectangular groove before bending, so that the top end is partially brought into contact with the back wall edge after bending. The key cylinder can be attached simply by inserting the key cylinder into the hole of an attachment unit. Freedom of the assembly order is therefore increased. Furthermore, the vibration of the key cylinder in the insertion direction of the key cylinder is reduced.
