  • Publication number: 20200072346
    Abstract: A gearshift lever device of this invention includes: a shift-lock lever that restricts a downward movement of a position pin when the gearshift lever is in a parking position; and a forcible release lever that presses a second arm and thereby forcibly rotates the shift-lock lever to allow the position pin to move downward. The forcible release lever includes a pressing portion that presses the second arm. The pressing portion includes a first corner portion that presses a position away from the rotational center of the shift-lock lever and a second corner portion that presses a position closer to the rotational center of the shift-lock lever than the position pressed by the first corner portion. When the pressing portion presses the second arm, the first corner portion first comes into contact with the second arm first and thereafter the second corner portion comes into contact with the second arm.

  • Publication number: 20200072345
    Abstract: A gearshift lever device includes: a main body case fixed on a body of a vehicle; and a gearshift lever supported by the main body case in a shiftable manner. The gearshift lever includes a tubular lever pipe and a lever holder having an insertion hole through which the lever pipe is inserted. The lever pipe includes a lever pipe upper portion forming an upper side of the lever pipe and a lever pipe lower portion forming a lower side of the lever pipe. A section modulus of the lever pipe lower portion is greater than that of the lever pipe upper portion. A shape of the lever pipe is changed in a part below an upper end of the main body case and above an upper end of the lever holder such that the lever pipe upper portion and the lever pipe lower portion have different shapes.

  • Patent number: 10161463
    Abstract: A driving force transmitting apparatus is provided which enables rotational resistance of rotating members to be suppressed while sufficiently supplying lubricant to a friction clutch. A driving force transmitting apparatus includes a clutch drum having a cylindrical portion, an inner shaft having an end housed in the clutch drum, a friction clutch having outer clutch plates that rotate along with the clutch drum and inner clutch plates that rotate along with the inner shaft, a piston that presses the friction clutch, and a housing in which a first housing chamber housing the friction clutch is formed and in which a storage chamber storing lubricant scooped up by rotation of the clutch drum is also formed. The lubricant stored in the storage chamber returns to the first housing chamber through an inner circulation path leading to inside the clutch drum and an outer circulation path leading to outside the clutch drum.

  • Patent number: 10138950
    Abstract: Provided is a driving force transmission device that can achieve further reduction in drag torque when it is not in operation and thus is not transmitting a driving force. A driving force transmission device includes: a clutch hub and a clutch drum; inner clutch plates spline-fitted on the clutch hub; outer clutch plates spline-fitted in the clutch drum; and a housing having a second accommodating chamber accommodating the clutch hub and the clutch drum. The inner clutch plates and the outer clutch plates are lubricated by lubricant. The driving force transmission device further includes a fin plate. The fin plate rotates with the clutch hub. By this rotation, the fin plate scoops up the lubricant in the second accommodating chamber to feed the lubricant to a reservoir chamber formed in the housing.
