Abstract: A pick-up style utility vehicle having a front seat and a rear seat. The pick-up style utility vehicle includes a cargo bed movement mechanism for supporting a cargo bed movably within a predetermined movement range in a back and forth direction. Also, a seat movement mechanism is provided for supporting the rear seat movably between a use position set to be within the movement range and a shunting position set to be out of or beyond the movement range.

Abstract: A pick-up style utility vehicle according to the present invention has a front seat, a rear seat, and a cargo bed in this order from front, a cabin frame surrounding a riding space, and a screen shield partitioning the cargo bed and a rear riding space in front of the cargo bed. The cargo bed is changeable between an expanded state in which the cargo bed is expanded forward to the rear riding space and a non-expanded state not occupying the rear riding space. All or part of the screen shield is angle shiftable between the expanded state and the non-expanded state.

Abstract: There is provided an exhaust apparatus for a vehicle. The exhaust apparatus includes a plurality of exhaust path forming members constituting an exhaust path from an exhaust port of an engine to an inlet of an exhaust muffler and connected to each other. End portions of the exhaust path forming members, made of different materials, are included in the plurality of exhaust path forming members and are connected to each other by a flange joint.

Abstract: The invention relates to a motorcycle engine arrangement which transmits a starting power to a crank shaft from a starter motor via a power transmission mechanism and a one-way clutch. The one-way clutch is installed at one end portion of the crank shaft, and a starter gear or a starter sprocket having a diameter smaller than an outer diameter of a clutch outer member is provided on the crank shaft portion further toward an outer side in an axial length direction of the crank shaft than the clutch outer member of the one-way clutch. Preferably, the clutch outer member is arranged further toward an outer side in the axial length direction of the crank shaft than a sprocket wheel for driving a cam or a gear for driving a cam provided at one end portion of the crank shaft.

Abstract: To provide an ultrafine particle grouting composition which is excellent in dispersibility and dispersion retainability and can be easily injected into minute spaces between particles of grounds, rock cracks, and the like.

Abstract: A grouting material which comprises an ultrafine particle material having a maximum particle size of 15 micrometer or less, containing 3 to 40% by mass of cement clinker, 60 to 97% by mass of and blast-furnace slag, 0.5 to 3 parts by mass of gypsum in terms of SO3 based on 100 parts by mass of the total amount of cement clinker and blast-furnace slag, and further comprises (i) 0.7 to 7 parts by mass of calcium-aluminate-based rapid-hardening admixture, (ii) 0.01 to 0.13 parts by mass of setting retarder, and (iii) 0.2 to 1.0 parts by mass of high-performance water-reducing agent, based on 100 parts by mass of the ultrafine particle material can maintain high injectability for long, and rapidly starts to set after injected to thereby exhibit a good short-term strength.
