  • Patent number: 12173783
    Abstract: A continuously variable transmission has an oil pan, an oil strainer located above the oil pan and a control valve unit located above the oil pan. The control valve unit has a shape having a cutting portion formed by a part of the control valve unit being cut out when viewed from an oil pan side. The oil strainer is arranged so as to overlap the cutting portion. With this structure, it is possible to ease a restriction on layout in terms of a height direction in the continuously variable transmission.

  • Publication number: 20240255863
    Abstract: A static elimination apparatus includes a conveyance unit to convey a sheet along a conveyance path, a non-contact type static elimination unit to perform static elimination on the sheet without being in contact with the sheet, and first and second guide members. The first guide member includes a contact portion to guide the sheet and a plurality of openings arranged in a sheet widthwise direction perpendicular to a sheet conveyance direction to expose the non-contact type static elimination unit to the conveyance path. The second guide member is disposed to face the first guide member and forms a part of the conveyance path together with the first guide member. The contact portion includes an inclined portion upstream in the sheet conveyance direction. The inclined portion is inclined so that a distance to the second guide member decreases downstream in the sheet conveyance direction.

  • Patent number: 11858352
    Abstract: A vehicle includes a case member, a stay member and a rib. The case member is supported by a frame of a vehicle body with a mount member being interposed. The stay member is suspended between a boss part of the case member and a member of a case member side in the mount member, a longitudinal direction of the stay member intersecting a longitudinal direction of the frame. The rib extends in the case member in a direction that is an extension of the longitudinal direction of the stay member at a root of the boss part.

  • Patent number: 11572943
    Abstract: A housing member for a power transmission device connected to a driving source via a torque converter housed in the housing member includes a torque converter side mating face closer to the torque converter. The torque converter side mating face has a single-wall structure and a double-wall structure, wherein two adjacent fastening regions are connected circumferentially by a wall in the single-wall structure, and wherein two adjacent fastening regions are connected circumferentially by each of two walls in the double-wall structure. The torque converter side mating face includes: an upper half region in which the double-wall structure has a greater proportion in area than the single-wall structure; and a lower half region in which the double-wall structure has a less proportion in area than the single-wall structure.
