  • Publication number: 20190106914
    Abstract: The present invention aims to reduce the operation noise of a latch device for a vehicle trunk lid when the lid is opened. A latch device for a vehicle trunk lid includes: latch 16 that is engaged with a striker; ratchet 18 that is engaged with latch 16; opening lever 43 that causes ratchet 18 to rotate in a direction in which ratchet 18 is disengaged from latch 16; output member 39 that rotates opening lever 43 in the release direction. Opening lever 43 is rotatable between an unblocked position where it is rotatable in the release direction and a blocked position where it is prevented from rotating in the release direction by colliding with the output member. When driven and rotated, output member 39 abuts against opening lever 43 that is in the unblocked position and rotates opening lever 43 in the release direction to the blocked position, and opening lever 43 is further rotated a predetermined angle by colliding with output member 39 in the blocked position.

  • Publication number: 20180298652
    Abstract: A hood lock apparatus includes: a primary lock portion holding a hood in a fully closed state; and a secondary lock portion holding the hood in a half open state and including a catcher attached to a vehicle body, a base attached to the hood, and a latch supported on the base, rotatable between a latching position and an unlatching position and including a hook portion locking the catcher when the hood is opened to the half open state with the latch being at the latching position, an operating portion operating the latch to rotate toward the unlatching position, and an abutment portion abutting the catcher when the hood is fully closed state with the latch being at the unlatching position. The latch is rotated to the latching position by the abutment of the abutment portion with the catcher.

  • Publication number: 20170342751
    Abstract: In an opening control device that controls the opening of an access panel door, a movable member of a detecting portion, which is pushed in by a main door that is in a closed state, is brought into direct abutment with a connection lever to move the connection lever, wherein the connection lever connects a drive lever, which is linked to operate with an opening operation of the door, and a driven lever, which releases the locking by locking portions, wherein the connection lever has a displacement area which includes a connecting position and in which maintains the connection of the drive lever with the driven lever, the connection lever is moved toward a disconnecting position within the displacement area when the movable member staying in a protruding position and is moved to the disconnecting position as the movable member is pushed into the pushed-in position.

  • Publication number: 20100326776
    Abstract: A garnish plate mounting structure allows a garnish plate to be installed to a caliper body without the need for any special machining of the caliper body, thus achieving improved general versatility. An engaging member is disposed along an external surface of a second pad opposing an arm portion of the caliper body. The engaging member has engaging portions which engage the second pad. The engaging member is held between the arm portion and the second pad. The garnish plate is disposed at an external surface of the caliper body and connected to the engaging member through the intermediary of connecting portions provided extendedly on both sides of the engaging portion.

  • Patent number: 7574900
    Abstract: A liquid state detection sensor in which temperature information of a urea aqueous solution is obtained on the basis of a voltage value acquired after the start of energization of a heating resistor corresponding to a resistance value of the heating resistor (S1-S6). Damage to the heating resistor is prevented by suspending the energization if the thus-obtained temperature is lower than or equal to the freezing point (S7: yes and S8). If the temperature is higher than the freezing point (S7: no), a voltage value corresponding to a resistance of the heating resistor after a lapse of 700 ms (S10 and S11) and a urea concentration of the urea aqueous solution are determined from a difference ?V from the previously acquired voltage value. A more accurate urea concentration can be detected by making a correction using the previously obtained temperature information of the urea aqueous solution (S13-S18).
