A vehicle has an engine and a fuel tank, which is located above the engine, mounted on a vehicle-body frame. A fuel pump, which supplies fuel is spaced-apart from the fuel tank and is located below the fuel tank and in front of the engine. Further, a center of the fuel pump in the vehicle-width direction is located so as to overlap a vehicle-body center line which extends in the longitudinal direction of the vehicle body. Additionally, the fuel pump is mounted on lower main frames, which are positioned below the vehicle body.

A headlight support structure for a saddle-type vehicle allows a headlight to be easily mounted easily on a handlebar of the vehicle. The headlight support structure includes a support member. The support member, in turn, includes: an attachment portion fixed to a mounting bracket disposed on a handlebar; a first holding portion covering the handlebar from an upward direction; and a second holding portion covering the handlebar from a forward direction. The headlight support member is supported on the handlebar by having the first and second holding portions supported on the handlebar with gaps interposed therebetween, while having the attachment portion fixed to the mounting bracket on the handlebar. The headlight is supported by first and right wall portions, extending respectively forwardly from right and left sides of a front portion of the support member.

A muffler structure capable of suppressing generation of abnormal noise in the muffler even when the outer and the inner tubes expand thermally. Provided is a double-pipe muffler structure including an inner tube and an outer tube. In the muffler structure, an annular front step portion and an annular rear step portion are formed in the inner tube, while the step portions is brought into contact, from inside, with the outer tube and thus are supported by the outer tube. The outer tube supports the front and the rear step portions by being brought into close contact with the step portions partially and elastically.

An intake system with an air cleaner case that is reduced in size with an enhancement in intake efficiency. A tubular tip end portion of a connecting tube provides a connection between the carburetor side and the air cleaner case with the tubular tip end portion being disposed in the air cleaner case. A tubular opening end portion is provided in an air cleaner element contained in the air cleaner case for connecting to the tubular tip end portion of the connecting tube. A large diameter portion is provided in a frame member serving as a core of the air cleaner element for supporting the tubular end portion and the tubular opening end portion in a condition wherein the tubular tip end portion and the tubular opening end portion are fitted to each other. The large diameter portion is larger in diameter than any other portion of the frame member.

An exhaust device includes an exhaust pipe connected at its upstream end to a cylinder head of the engine and an exhaust muffler connected to the downstream end of the exhaust pipe for suppressing the generation of noise from a heat insulating cover that covers a part of the exhaust pipe. A heat insulating cover covers a portion of the exhaust pipe near the engine and a stay is fixed to the heat insulating cover. The stay includes a supporting plate portion curved so as to partially surround the outer circumference of the exhaust pipe. A first vibration isolating member is provided that is sandwiched between the outer circumference of the exhaust pipe and the supporting plate portion, a band member is tightened to mount the supporting plate portion to the exhaust pipe, and a second vibration isolating member is sandwiched between the supporting plate portion and the band member.
摘要:
There are included steps of forming a silicon nitride layer on a silicon layer or a silicon oxide layer, loading the silicon layer or the silicon oxide layer and the silicon nitride layer in a dry etching atmosphere, and selectively etching the silicon nitride layer with respect to the silicon layer or the silicon oxide layer by flowing a fluorine gas consisting of any one of CH2F2, CH3F, or CHF3 and an inert gas to the dry etching atmosphere. Hence, in the etching process of the silicon nitride layer, the etching selectivity of the silicon nitride layer to Si or SiO2 can be enhanced and also etching anisotropy can be enhanced.
