Wheel stopper (chock) for tire changes

According to the Owner’s Manual, when changing a flat tire, to keep the car from moving when it is raised with the jack, you’re supposed to chock the opposite wheel:



In the U.S., the Prius doesn’t come with a chock, but the same page in the Japanese edition of the manual has this helpful note:

※ 輪止めは、トヨタ販売店で購入することができます。
[Wheel stopper can be purchased at a Toyota dealer.]​

So I did, and this is what I received:



It’s metal and might rattle, so I bought the bag for it, too:



The wheel stopper weighs about 410 grams. Folded, it’s 134 mm × 88 mm × 28 mm; unfolded for use, it’s 94 mm high. The bag, lying flat, is 165 mm × 125 mm outside and about 158 mm × 110 mm inside.

Toyota has a video on YouTube (in Japanese) that shows the wheel stopper in use, starting at 2′05″.

Here are the Toyota part numbers and list prices in the U.S. and Japan:

09184-00010 – Stopper, Wheel ($25.31; ¥770)
09120-28040 – Bag, Tool ($9.48; ¥250)​

I bought mine from IMPEX JAPAN, but Toyota dealers in the U.S. are also offering them online; discounts of 33% or so from the list price aren’t hard to find.

In Japan (and for Mirai in the U.S.), the wheel stopper is part of an in-car tool kit sold as a dealer option, with a larger tool bag and a few common hand tools:

09120-16030 – Bag, Tool ($37.73; ¥450)
99913-11500 – Pliers (slip-joint; $11.92; ¥400)
99915-10700 – Driver, Screw (reversible, flat-blade and cross-head; $12.90; ¥460)
99914-10810 – Spanner (open end wrench, 8 × 10 mm; $7.44; ¥240)
99914-11214 – Spanner (open end wrench, 12 × 14 mm; $12.73; ¥400)​

I didn’t buy any of these, and if you need tools, I’d suggest instead buying locally or from Toyota’s line of hand tools for service use. The latter have 09xxx-xxxxx part numbers; most are made for Toyota in Japan by firms such as Kyoto Tool, Vessel, and O.H. Industrial, with quality to rival top American or European brands. There is a thread on the IH8MUD forum with lots of pictures of Toyota tools.

 

The Electronic Parts Catalogs don’t go quite that far back, but the same part number is definitely listed for the 1979 Corolla. I hope the engineer who designed it is enjoying a pleasant retirement.
