Provided are a power transmission switching mechanism allowing reduction in size and weight in a simple configuration with a minimized piece-part count, and a transmission provided therewith. The power transmission switching mechanism includes a sleeve that moves in an axial direction of a rotation shaft, a hub section provided integrally with a gear for holding a sleeve axially slidably and unrotatably, and a dog spline installed to a pulley piston fixed to the rotation shaft for meshing the sleeve. In a state in which the sleeve is held to the hub section, the rotation shaft is disengaged with the gear and a relative rotation thereof is allowed. Meanwhile, when the sleeve axially moves from the hub section, the rotation shaft engages with the gear and both thereof rotate integrally.

Power transmission switching mechanism and transmission

A hybrid vehicle is provided with a first transmission passage for transmitting driving force of an engine to driving wheels and a second transmission passage for transmitting driving force of a driving motor to the driving wheels, and driven by selectively using or in combination of the first transmission passage and the second transmission passage. The hybrid vehicle includes: a first input gear for inputting the driving force of the engine; a second input gear for inputting the driving force of the driving motor; and an idle gear meshed with the first input gear and the second input gear, and transmitting at least one of the driving force of the engine and the driving force of the driving motor toward the driving wheels. The driving force to be input from at least one of the first input gear and the second input gear is transmitted to the driving wheels via the idle gear and the final differential gears.

A transmission breather system is provided in which a subassembly is formed by supporting a shift select shaft, moving in the axial direction according to a select operation of a shift lever, and a select spring, maintaining the shift select shaft in a neutral position, on a cover member. Moreover, a breather chamber is formed between the cover member and an indentation of a transmission case by inserting the shift select shaft into an opening formed on the bottom wall of the indentation of the transmission case to connect the cover member to the transmission case, and the select spring is housed in the breather chamber. Thus, with regard to the transmission breather system, it is possible to form a breather chamber whose maintenance is easy while avoiding an increase in the size of the transmission case.
