A chain tensioner includes a base frame secured to each of front and rear banks, a slider plate shiftable in the extending direction of the base frame, and a tensioner provided to straddle between the base frame and the slider plate. The slider plate is biased to elastically deform and arcuately bend the tensioner, which applies a tensile force to each of cam chains transmitting the rotation of a crankshaft. In the chain tensioner, upper securing portions are provided in an upper portion of the base frame so as to be secured to each of the front and rear banks in the bending direction of the tensioner. A lower end of the base frame extends to a position facing the inside of the crankcase to provide a lower securing portion which is secured to each of the front and rear banks perpendicularly to the bending direction of the tensioner.

A vehicle internal combustion engine wherein the vertical height of a crankcase is made short in addition to making short the anteroposterior (front to back) length of the crankcase. A vehicle internal combustion engine is configured such that a crankshaft, a main shaft, a counter shaft and an output shaft are arranged in parallel in a crankcase with the main shaft being disposed to the rear of the crankshaft and the counter shaft is disposed to the rear of the main shaft. The output shaft is disposed below and forward of the counter shaft.

An optical device used, for example, in an add/drop multiplexer, a dynamic gain equalizer or a optical power monitor. The optical device includes (a) a substrate; (b) a first slab waveguide formed on the substrate; (c) channel waveguides of differing lengths formed on the substrate, light output from the first slab waveguide being input to the channel waveguides; and (d) a second slab waveguide formed on the substrate, light output from the channel waveguides being input to the second slab waveguide. An end face of the second slab waveguide shares a face with an end face of the substrate. The optical device has low loss characteristics.
