Abstract: A continuously variable transmission includes: a first pulley having a first fixed sheave and a first movable sheave; a first cylinder forming a first oil chamber with the first movable sheave; a second pulley having a second fixed sheave and a second movable sheave; a second cylinder forming a second oil chamber with the second movable sheave; and a transmission belt wound around the first pulley and the second pulley. The first cylinder has a first member that is fixed to a first shaft and a second member that is joined to an outer peripheral portion of the first member. A bearing is interposed between an outer periphery of the first member and an inner periphery of a case. A thickness, in an axial direction, of a portion of the first member that is configured to directly abut against the first movable sheave is larger than a thickness of the second member.

Abstract: An automotive seatbelt take-up device has a primary spiral spring biasing a take-up shaft in a seatbelt take-up direction. A spring clutch transfers rotation of the take-up shaft in a seatbelt drawing-out direction to a ring. A secondary spiral spring is capable of generating rotational biasing force on the take-up shaft in a direction opposite that of the primary spiral spring. Thus, the present invention provides an automotive seatbelt take-up device that can reduce both the drawing-out force and the take-up force of a seatbelt when the seatbelt is being worn.
