Abstract: A bonded body formed by frictional pressure-contact, includes: a first member including an end surface and a hollow portion with an opening in the end surface; and a second member including a body portion bonded to the end surface and a protrusion portion protruding from the body portion, the protrusion portion being accommodated in the hollow portion, wherein at least one of an inner peripheral surface of the hollow portion and an outer peripheral surface of the protrusion portion includes an inclined portion inclined to a radial direction of the opening, while the other is in contact with the inclined portion.

Abstract: A fluid pressure cylinder includes a cushion bearing provided movably on an outer periphery of the piston rod; a flange portion provided on the piston rod by facing the piston with the cushion bearing between them; and a collar provided movably in a radial direction on the outer periphery of the piston rod between the cushion bearing and the flange portion. End surfaces of the cushion bearing and the collar are inclined symmetrically to a center axis of the piston rod, and end surfaces of the flange portion and the collar are formed having plane shapes crossing the center axis.

Abstract: The present invention provides carboxymethylcellulose or a salt thereof that can prevent defects such as streaks and pinholes from occurring in the obtained electrode when it is used as a binder for an electrode of a nonaqueous electrolyte secondary battery. The present invention provides carboxymethylcellulose or a salt thereof of which ratio of a dry mass A to a dry mass B is less than 50 ppm when 2 liters of a 0.3 mass % aqueous solution of the dry mass B of the carboxymethylcellulose or a salt thereof is prepared, the entire amount of the aqueous solution is filtrated through a 250-mesh filter under a reduced pressure of ?200 mmHg, and the dry mass A of a residue on the filter is measured after filtration. The applications of the carboxymethylcellulose or a salt thereof are also provided.

Abstract: A brake system in a buggy includes first and second brake shafts which are disposed on one side of the left and right differential output shafts in a longitudinal direction of the vehicle and in parallel to the left and right differential output shafts and which are driven at increased speeds by the left and right differential output shafts. The first and second brake shafts and the first and second brakes are accommodated within a reduction case, so that the first and second brakes are cooled by lubricating oil within the reduction case. Thus, the brake system in the buggy can be mounted at a high level above the ground; is excellent in dustproof and waterproof properties; is cooled satisfactorily, and moreover, is capable of reliably braking left and right wheels simultaneously.

Abstract: A brake for a buggy vehicle includes a plurality of rotatable friction brake plates which are axially slidably and relatively non-rotatably coupled to the input shaft of a reduction device spline-coupled to a propelling shaft, a plurality of stationary friction brake plates alternately superposed with the rotatable friction brake plates, a brake non-rotatable housing which houses the group of the rotatable and stationary friction brake plates therein and which supports said stationary friction brake plates for axially sliding movement and against rotation, a pressure-receiving portion provided in the brake housing to carry one side of the group of the rotatable and stationary friction brake plates, and an operating device capable of urging the other side of the group of the rotatable and stationary friction brake plates against the pressure receiving portion.

Abstract: A wet multi-plate clutch includes a clutch outer connected to an input member, a clutch inner relatively rotatably disposed within the clutch outer and connected to an output member, a plurality of first friction plates axially slidably spline-fitted to an inner peripheral wall of the clutch outer and accommodated within the clutch outer, a plurality of second friction plates axially slidably spline-fitted to an outer peripheral wall of the clutch inner and superposed one on another alternately with the first friction plates, and a clamping device capable of clamping groups of the first and second friction plates axially to bring adjacent ones of the first and second friction plates into friction engagement with each other. In this wet multi-plate clutch, stopper devices are mounted at opposite ends of a spline groove in the clutch outer for limiting the distance of sliding movement of spline teeth of the group of the first friction plates.
