  • Patent number: 11088383
    Abstract: A fuel cell vehicle that reduces damage on a fuel gas pump and deformation of a dash panel toward a cabin side when the vehicle collides head-on. The fuel gas pump is secured to a stack frame via a bracket such that a rotation, axis line of a motor adapted to drive a fuel gas pump inclines with respect to a reference line along the from-rear direction of the vehicle in plan view of the vehicle. Two fastening members secure the stack frame to the bracket in a state of being respectively inserted through a through hole and a cutout portion formed at a mounting portion. The cutout portion is formed such that, when the bracket turns together with the fuel gas pump with respect to the stack frame using one fastening member as a rotational center, the other fastening member exits out of an opening of the cutout portion.

  • Patent number: 10794342
    Abstract: A pump unit includes an insertion guide member that extends in a longitudinal direction of the pump unit and is used to guide the pump unit at a time of inserting the pump unit into an opening portion of a fuel tank. The insertion guide member includes a stopper portion and a guide portion that are arranged along an edge part of the insertion guide member. When the pump unit is projected in the longitudinal direction onto a plane of projection, the stopper portion protrudes outward from an imaginary circle, which has a fitting portion's diameter, on the plane of projection. The guide portion guides the pump unit in a rotational direction relative to a stay. A cross section of the pump unit taken along a guide portion orthogonal plane is set to be within the imaginary circle, which has the fitting portion's diameter.

  • Patent number: 10797328
    Abstract: A fuel cell module that can suppress deterioration of sealability caused by liquid (water) that has collected in a system is provided. In the fuel cell module, a port portion of a gas-liquid separator is provided with a discharge groove in a region of from the outer periphery toward the inner periphery of the port portion, and the bottom portion of the discharge groove is inclined so as to become lower toward the inner side. Liquid (water) that is stuck between the port portion and a housing portion is discharged, due to its own weight or the like, to the inside of the port portion (to the side of the gas-liquid separator) through the discharge groove.

  • Patent number: 7535083
    Abstract: A lead frame has a pair of side frames each having a plurality of positioning holes and spaced apart from each other in a width direction of the lead frame. At least one section bar extends between the pair of side frames. First lead sections extend from the section bar and are arranged at predetermined intervals along the width direction of the lead frame. Second lead sections extend from the section bar along the width direction of the lead frame and are disposed in confronting and spaced-apart relation to the respective first lead sections in a longitudinal direction of the lead frame to define a frame area extending between the pair of side frames. Each of the second lead sections has a pair of separate and independent protruding portions disposed adjacent one another.

  • Patent number: 7345411
    Abstract: A surface mount type piezoelectric vibrator comprises a piezoelectric vibrator having a piezoelectric vibrating piece bonded to an airtight terminal with a lead terminal and sealed by a cylindrical bottomed metal sealing tube. An electrode terminal is connected to the lead terminal so that a tip of the electrode terminal is disposed approximately at the same position as a tip of the lead terminal in a longitudinal direction of the surface mount type piezoelectric vibrator. The piezoelectric vibrator is coated with a mold resin.
