Abstract: A shielding case is tightly mounted on a rim of a wheel having a tubeless tire thereon. A rocking rod extending from the case into the interior of the tire is supported at its substantially intermediate portion for pivotal movement from a neutral position, and a warning element for attracting the attention of a driver responds to the movements of the rod, when the tire is deflated due, for instance, to puncture. The warning element may either be one end of the rocking rod which strikes the case to give a series of sounds or an electromagnetic switch arrangement which energizes a buzzer.

Abstract: An electric bicycle is provided that can increase the diameter of the joining section between a crankshaft and a crank arm, suppress an increase in manufacturing cost, and minimize a size increase of a hanger with a torque sensor disposed in the hanger. A crankshaft 17 is divided into a crankshaft body 17A on the periphery of which a torque sensor 23 is disposed, and an auxiliary crankshaft 17B connected to one side of the crankshaft body 17A. A diameter D1 of the joining section between the auxiliary crankshaft 17B and a crank arm 18B and a diameter D3 of the joining section between the crankshaft body 17A and a crank arm 18A are larger than a diameter D2 of the connecting section between the crankshaft body 17A and the auxiliary crankshaft 17B.

Abstract: An electrically assisted bicycle is provided with a so-called single-shaft motor drive unit that can satisfactorily keep torque detection capability. The outer periphery of a crankshaft 7a has a cylindrical human-power transmission member 28 having a torque sensor 31 for detecting a human driving force and a combined force member 29 that combines a human driving force and an auxiliary driving force from a motor 21. A one-way clutch is not provided on a driving force transmission path including the crankshaft 7a, the human-power transmission member 28, and the combined force member 28. The human-power transmission member 28 and the combined force member 29 are always rotated in response to a rotation of the crankshaft 7a.
