Body: <p>I'd be grateful if someone could help me identify this part. It's from the Lego Power Functions Ideas book, which has a gallery of required parts, but without part numbers.</p>

Comments.Text: The photo is from the 2nd book in a set of two by Yoshihito Isogawa. The appendix lists all the parts required for the models in each book, and the required quantity. It also states (in brackets) how many of each part is required for the models in the sister book. I cropped this out unintentionally from the photo.
