ないと接触部の摩耗が早くなり寿命が短くなるという問
題が生じる。By the way, in the above-described lubrication structure shown in FIG. 3, since the lubrication path from the pump to the lubrication section is long, when the friction type continuously variable transmission is started up, the lubrication oil is needed at the necessary places. A certain amount of time elapses before the supply, and during that time, the frictional contact portion operates in a nearly non-lubricated state. For this reason, when the lubricating oil is supplied from the oil pump at the time of start-up, if the lubricating oil is not supplied to a certain extent, there is a problem that wear of the contact portion is accelerated and the life is shortened.

題が生じる。In particular, in the friction contact portion between the double cone and the outer ring of the friction type continuously variable transmission mechanism, since it is the power transmission portion, lubrication at the time of starting becomes a problem. For this reason,
The problem of insufficient lubrication at start-up can be solved if the frictional contact part is lubricated with oil bath and the frictional contact part is always immersed in the lubricating oil. Causes a problem that the transmission efficiency decreases and the transmission efficiency decreases.

It is an object of the present invention to provide a friction type continuously variable transmission that can prevent running out of lubricating oil and has a small influence on the transmission efficiency at the rated rotation.

構成を採用したものである。In order to solve the above problems, the present invention connects a gear mechanism for transmitting the rotation of an input shaft to an input portion of a friction type continuously variable transmission mechanism. In the lower part of this speed change mechanism, an oil tank in which the lubricating oil of the friction type continuously variable speed change mechanism and the gear mechanism is concentrated is provided, and an oil pump for sucking the lubricant oil in the oil tank is incorporated in the input shaft of the gear mechanism. In a frictionless continuously variable transmission in which a passage is provided in the housing body of the transmission for supplying the lubricating oil sucked up by the oil pump to required parts of the transmission mechanism and the gear mechanism, friction is generated in the housing body of the transmission. An oil reservoir is provided directly below the frictional contact member of the continuously variable transmission, and the lower part of the frictional contact member is immersed in the lubricating oil housed in the oil reservoir. It is.

れて摩擦接触部に潤滑油を供給することができる。Since the lower part of the friction contact member is immersed in the lubricating oil housed in the oil reservoir, the inside of this reservoir is kept from when the transmission is started until the lubricating oil is supplied to the friction contact part by the pump. The lubricating oil in the area can be scraped up and supplied to the friction contact portion.

Has little effect on.
