摘要:
A support section structure for a swing arm provides a well-balanced state for the weight of the vehicle in a widthwise direction and for efficiently increasing the rigidity of a vehicle body frame without inviting a significant increase in the weight of the vehicle body. A swing arm is provided for supporting a rear wheel Wr for rotation and is supported for a rocking motion on a center frame. An output power shaft of a power source is transmitted to the rear wheel Wr through a drive shaft. A left outer side frame and a intermediate frame, which support a front end portion of the swing arm for pivotal motion, are provided on the center frame. A right outer side frame disposed on the outer side in the vehicle widthwise direction with respect to the drive shaft on the intermediate frame is provided integrally against removal on the center frame.

Disclosed is a key sheet efficiently diffusing local heat generated by a device mounted on a board. A key sheet has a base sheet formed of a rubber-like elastic material in which a heat conductive filler is mixed. Thus, if a semiconductor device on a board generates heat, it is possible to suppress local heat storage by the heat conductive filler of the base sheet. Further, there is no need to provide a separate member for heat diffusion between the board and the key sheet, making it possible to realize a reduction in thickness. Thus, with the key sheet, it is possible to meet the requirement for heat diffusion to eliminate local heat storage in electronic apparatuses, and the requirement for a reduction in the thickness and weight of electronic apparatuses.

Disclosed is a key sheet efficiently diffusing local heat generated by a device mounted on a board. A base sheet of a key sheet is provided with a heat diffusion sheet. The heat diffusion sheet is provided with a graphite sheet and a resin film and, in some cases, a thin metal plate. The base sheet itself thus constitutes the heat diffusion sheet, so even if no member for heat diffusion is provided between a board and the key sheet, it is possible to diffuse local heat generated by a semiconductor device in the face direction of the base sheet. Thus, with the key sheet, it is possible to meet the requirement for heat diffusion to eliminate local heat storage in electronic apparatuses and to meet the requirement for a reduction in the thickness and further in weight of electronic apparatuses.

A front end portion of a rear swing arm of a motorcycle is pivoted to a vehicle body frame via a rear swing-arm bracket. A rear wheel is rotatably supported by a rear end portion of the rear swing arm. The rear swing arm is provided with a shaft drive mechanism for driving the rear wheel. The rear swing-arm bracket includes a left/right pair of frame members, cross members and a connection portion. A front end portion of the shaft drive mechanism faces a right-side opening at a position biased towards the frame member. The connection portion is extendedly provided at a position biased toward the center line (the center) extending along the longitudinal direction of the vehicle. The front end portion of the rear swing arm is fastened to the frame member and the connection portion via a pivot shaft and a nut in a left-side opening.

A cartridge-type oil tank construction is disclosed which is capable of effectively preventing oil leakage from the construction even when the construction falls down in any direction. The oil tank construction includes a stationary tank, an integrally formed tank supporting means arranged near one side end of the stationary tank to dispose a cartridge tank therethrough on the stationary tank, and a combination of a projection and a cutout which serves to allow an oil supply port of the tank supporting means to constantly face the other side end of the stationary tank opposite to the one side end thereof.

An automatic fire-extinguishing device for an oil burner is disclosed which is capable of manually carrying out the fire-extinguishing at the occurrence of any trouble in the oil burner as well as at the occurrence of earthquakes with good reliability and significant simplicity. The automatic fire-extinguishing device includes a movable lever which is adapted to be operated by a manual operation lever mounted on a movable shielding plate at the time of fire-extinguishing to upward move a combustion cylinder with respect to a wick receiving case through a lever mechanism to form a space between the cylinder and the case and receive the shielding plate into the space, so that the fire-extinguishing may be accomplished.

A spacer structure for a heating appliance is disclosed which is capable of allowing the package of the heating appliance to be significantly simplified and small-sized to reduce the cost and is simple in construction. The spacer structure includes a spacer formed into a substantially U-shape and having a pair of inward bent ends and projections provided at the inward bent ends which are fitted in through-holes of a mushroom shape to rotatably securely connect the spacer to the heating appliance.
