Abstract: An engine clutch device includes first and second alternately stacked frictional power transmitting members and a clutch pressure member for axially bringing the frictional power transmitting members into pressure contact. The clutch device includes an oil supply portion adjacent to a distal end of power transmission shaft. The clutch device has an oil supply structure including a clutch lifter member with a flange portion axially facing the distal end of power transmission shaft, to axially shift the clutch pressure member to release the pressure contact of the frictional power transmitting members. The flange portion has a bowl-shaped portion extending axially to surround the one end portion of the power transmission shaft. The bowl-shaped portion including the flange portion functions to guide oil axially inward along the power transmission shaft and serves to provide an improved oil supply effect to the frictional power transmitting members.

Abstract: A rear-wheel suspension system for a two-wheeled vehicle capable of further reducing a vehicle width. An upper end of a coil spring of a shock absorber includes a tubular damper case, a rod connected to a piston disposed within the shock absorber and protrusively provided to be capable of making strokes with respect to the tubular damper case and an external hydraulic sub-tank positioned to be lower than an upper end of the shock absorber. Vehicle body component parts include a connecting tube and the sub-tank disposed to be close to the shock absorber above the coil spring.

Abstract: An exhaust device of an internal combustion engine for reducing exhaust sound and for suppressing the occurrence of a torque valley. A sound-deadening and pressure-dissipating device connected to the downstream end of an exhaust pipe includes a spherical member having an opening portion opening toward a downstream edge of the exhaust pipe. Exhaust gas from the exhaust pipe is reflected by an inner spherical surface of the spherical member to reduce exhaust pressure in the spherical member and then is discharged from the opening portion.

Abstract: A cutter knife 10 includes a case 12 having a slit 27 in a top wall 22 constituting an upper end portion, a cutter blade 14 provided such that the cutter blade 14 may appear from a forward end of the case 12, and a slider 15 holding the cutter blade 14 and provided movably in a forward and rearward direction along a guide member 13 in the case 12. The slider 15 includes a slider body 42, an actuating member 44, and a plate spring 17, the plate spring 17 being provided to keep the actuating member in an initial position relative to the slider body.

Abstract: A discharge container that discharges an appropriated amount of a creamy cosmetic, medical supply, or the like. The discharge container may include a cylindrical body and a cylindrical lid with a top. The lid covers an opening, and is rotatably engaged with the opening. A top wall portion of the top is brought into sliding contact with an upper end surface of a rotatable partitioning plate such that any contents in the discharge container are pressed by relative rotation between the container body and the lid, resulting in the contents being discharged through a discharge opening provided on the top wall.

Abstract: A discharge container includes a cylindrical container body with a bottom which includes a support extending upward from a bottom wall along a center axis, and a fixed partitioning plate extending from a region from a peripheral wall to a bottom wall as a base end to partition the inside of the container body in a radial direction; a rotor which includes a cylindrical shaft piece rotatably engaging with the outer surface of the support, and a rotatable partitioning plate extending from the cylindrical shaft piece as a base end to be arranged in a radial direction along with the fixed partitioning plate; and a cylindrical lid with a top which has a top wall having a saucer-shaped upper surface, and a downwardly extending shaft extending downwardly from the lower surface of the top wall and engaging with the cylindrical shaft piece from above such that the downwardly extending shaft cannot rotate therein, the lid covering the cylindrical opening as a lid and rotatably engaging with the cylindrical opening, wher

Abstract: A structure for mounting a rear fork in a vehicle, including a body frame having left and right pivot supporting holes; left and right arm portions of a rear fork having supporting holes which are coaxial with the right and the left pivot supporting holes of the body frame a pivot shaft penetrating the pivot supporting holes of said body frame and the supporting holes of the left and right arm portions of the rear fork, said rear fork being rotatively supported on the pivot shaft and being rotatable with respect to said body frame. A tapered cutout is provided on the end surface portion of the collar to be pressed into the pivot supporting hole of the engine, so as to allow the pivot shaft to deflect.

Abstract: The operation of the rear wheel will be accurately conveyed to the driver when the rotation characteristic of the rear fork draws a smooth straight line or curved line. Between left and right pivot supporting holes of the body frame, pivot supporting holes of the engine are arranged so as to become coaxial with each other. Between the pivot supporting holes on the body frame side and on the engine side, there are arranged supporting holes capable of being rotated on left and right arm portions of the rear fork so as to become coaxial with the pivot supporting holes, respectively. A pivot shaft is provided so as to penetrate the pivot supporting holes of the body frame. Thus, on the end surface portion of the collar to be pressed into the pivot supporting hole of the engine, there is provided a tapered cutout so as to allow the pivot shaft to deflect.
