Abstract: An oil exchange timing indicating apparatus for vehicles capable of informing a user of an exchange timing of oil on the basis of the degree of degradation of oil as quickly as possible. An oil exchange timing indicating apparatus includes an odometer for integrating vehicle travel distances, an operation time integrator for integrating operation times of an engine mounted on the vehicle, an oil exchange informing device for informing a user of an exchange timing of oil, and a controlling device for starting, when either an integrated value of the travel distances or an integrated value of the operation times, based on signals from the odometer and the operation time integrator exceeds a preset value, the oil exchange informing device to inform the user of the exchange timing of oil.

Abstract: A transmission for an electric vehicle that allows forward movement in a first shift stage with hydraulic pressure failure and permits forward and rearward towing. The first shift stage of the transmission T is established by a main first-shift gear 19 which is brought into and out of engagement with a main shaft Sm connected to an electric motor Mm through a towing clutch 50, and by a counter first-shift gear 26 carried on a counter shaft Sc with one-way clutch 47 interposed therebetween. During backward towing of the vehicle, the rotation of a driven wheel is reversely transmitted by way of the counter shaft Sc, the one-way clutch 47, and the counter first-shift gear 26 to the main first-shift gear 19, but by actuating the towing clutch 47 into a disengaged state to disengage the main first-shift gear 19 from the main shaft Sm, the electric motor Mm can be prevented from being forcibly driven and being damaged.
