Abstract: A locking device includes a lock portion on one of a fixed body or an opening/closing body, a rod on the other member, and a protrusion protruding from the other member. The rod has a recess surrounded by a pair of first walls facing each other in a sliding direction of the rod and a pair of second walls facing each other in a direction orthogonal to the sliding direction. A first elastic piece extends from one of the first walls toward the other and applies an elastic force against a tip end surface of the protrusion, and a pair of second elastic pieces extend from the second walls. Each of the second elastic pieces has a receiving surface that engages with a back surface of a flange portion of the protrusion, and is configured to elastically abut against a side surface of the protrusion.

Abstract: A valve device for a fuel tank includes: a housing including a peripheral wall portion, a partition wall, a valve chamber, a ventilation chamber, and an opening; and a float valve that is accommodated in the valve chamber so as to be able to rise and descend to open and close the opening. The housing includes a float valve support portion that supports the float valve. A full tank regulation opening that opens in an axial direction and that is configured to allow the inside of the fuel tank and an inside of the valve chamber to communicate with each other, is formed in the peripheral wall portion above the float valve support portion. The full tank regulation opening enables continuous refueling from the refueling nozzle when the full tank regulation opening is not immersed, and stops the continuous refueling when the full tank regulation opening is immersed.

Abstract: An air damper is provided. A piston member includes a stopper portion configured to come into contact with a cap in a state that a rod is pulled out to a maximum extent, and a deflection regulating portion configured to be positioned inside the engagement claw in the state to regulate an inward deflection of the engagement claw. An attachment portion rotatably attached to an attachment target portion is provided at an end portion of the rod. A contact surface is formed on the inner side of the engagement claw when viewed in an axial direction of the cylinder, the contact surface being capable of coming into contact with the deflection regulating portion when the rod swings in a direction of a rotation axis of the attachment portion with respect to the attachment target portion or in a direction intersecting the rotation axis.

Abstract: There is provided a locking device including: a base member; a lock bar member; and a drive member. The base member includes a pair of facing surfaces sandwiching and supporting the lock bar member. The lock bar member includes a lock portion, a first bar portion extending in a sliding direction of the lock bar member, and a second bar portion extending in a direction intersecting the sliding direction and connecting the first bar portion and the lock portion. A first stepped portion is formed on the first bar portion, and a second stepped portion is formed on the second bar portion. Each of the facing surfaces is provided with step portions each of which faces the first stepped portion and the second stepped portion respectively in the direction intersecting the sliding direction at positions sandwiched between the first stepped portion and the second stepped portion.

Abstract: As shown in FIG. 5B, the pushing portion 44 of the operation member 22 pushes the sliding surface 46 of the driving member 30, and the driving member 30 is retracted. In this way, the driving member 30 is driven by an operation of the user.
A lock device attached to a stationary body so that an opening and closing body is locked in a closed state with respect to the stationary body includes a driving member that is driven in response to movement of an operation member, and a rod movable in a longitudinal direction. The driving member includes a coupling portion coupled to the rod. The rod includes a lock portion engageable with and disengageable from a lock hole of the opening and closing body, and a holding portion holding the coupling portion so that the coupling portion is slidable in a moving direction of the rod. When the rod is moved in a lock releasing direction in which lock of the lock portion is released by the driving member, the holding portion and the coupling portion move in the lock releasing direction. ---

Abstract: A hose clamp includes a clamp main body including a ring portion and a pair of knob portions; and a holder. The holder includes a main body portion, a pair of holding walls, and an operation portion. An inner surface on a distal end side of one holding wall includes a protrusion that protrudes more largely inward than an inner surface on a distal end side of other holding wall. And in a state where the pair of knob portions are close to each other, a distal end of one knob portion in a peripheral direction is engaged with the inner surface of the one holding wall, and the other knob portion is engaged with the inner surface of the other holding wall, so that the ring portion is kept in a diameter-increased state.
