A lubrication system for a power transmission unit that supplies oil to a starting clutch in an appropriate amount irrespective of an engagement state of the starting clutch. When the friction clutch is completely engaged or disengaged, a first control valve is brought into a low inflow rate mode, and the second control valve is brought into a low outflow rate mode. When the friction clutch is engaged while causing a slip the first control valve is brought into a high inflow rate mode, and the second control valve is brought a high outflow rate mode.

Lubrication system for power transmission unit

A variable transmission system for a vehicle is configured such that, when a magnitude of a hydraulic pressure detected by an hydraulic pressure sensor is a first predetermined value or more, a chord portion of a chain belt is pressed such that a raceway length of the chain belt is extended by at least a circumferential extension amount of the chain belt at the time when the magnitude of the hydraulic pressure is the first predetermined value. Hereby, it is possible to restrain the chain belt from coming off from a sheave even in a low vehicle speed range, at a low cost, without causing a fuel efficiency decrease and a driving torque decrease of the vehicle.

Variable transmission system for vehicle

A belt-driven continuously variable transmission in which a collision noise of a broken chain belt can be suppressed is provided. In the transmission, a chain belt is applied to belt grooves of pulleys to transmit power therebetween, and a speed ratio is varied by changing a width of the belt groove of at least one of pulleys. The transmission comprises: a guiderail that is contacted to the chain belt to suppress vibrations in the chain belt and that is allowed to rotate with a change in an inclination of the chain belt; and a pushing mechanism that applies a load to the guiderail to rotate the guiderail to alter an inclination of the chain belt in a direction to increase the speed ratio when the chain belt is broken.

Belt-driven continuously variable transmission

A head-up display device includes a housing, a reflecting member, a projection light emitting unit, and a vibration transmitting member. The housing is fixed to a vehicle. The reflecting member is rotatably supported by the housing and is held at a rotation position. The projection light emitting unit projects projection light corresponding to information onto a window of the vehicle through the reflecting member. The vibration transmitting member is provided between the housing and the reflecting member and has elasticity. The vibration transmitting member is fixed to the housing and makes contact with the reflecting member in an elastically compressed state in an entire rotatable range of the reflecting member.

Head-up display device

The present invention is to provide a combination meter having a close arrangement of a plurality of drive axles of pointers so as to save a space thereof and provide a good design thereof. The combination meter includes a speedometer and a tachometer. A speedometer dial and a tachometer dial are disposed on the circumference of one circle. The pointers each include a deadweight holder to hold a deadweight. The deadweight holders are separately overlapped each other in directions of the drive axles. One of the drive axles is disposed on the center of the circle and the other is disposed close to the center.
