An internal combustion engine includes a cylinder head, a support structure, a cam pulley, and a seal member. The support structure is provided above the cylinder head and supports the camshaft. The cam pulley is provided at an end of the camshaft. A timing belt is wound around the cam pulley. A seal member is provided to cover a gap provided between the cylinder head and the support structure at a facing surface facing the cam pulley. The seal member provides sealing between the cylinder head and the support structure in an axial direction of the camshaft.

Internal combustion engine

A balance device for an internal combustion engine includes a crankshaft and a balance shaft. The crankshaft includes a CS eccentric weight. The balance shaft includes a BS eccentric weight. A CS connected point deviated from the CS main shaft, and a BS connected point deviated from the BS axial shaft are connected with a connection rod. A CS connection mechanism that enables relative rotation of the crankshaft and the connection rod is provided at the CS connected point. A BS connection mechanism that enables relative rotation of the balance shaft and the connection rod is provided at the BS connected point. A guide section guides a motion of the connection rod so that the balance shaft rotates in an opposite direction to the crankshaft.

Balance device for internal combustion engine

An electrically driven vehicle equipped with a battery usable for running in which a power generation unit of engine driven type that charges the battery is detachably mounted on a vehicle body, includes including a first connection part that brings a high-voltage system in which the battery and the power generation unit are electrically connected together into a connected state in a state in which the power generation unit is mounted in a mounting position and brings the high-voltage system into a disconnected state in a state in which the power generation unit is dismounted from the mounting position, whereby the first connection part switches a connection state of the high-voltage system in accordance with installation or removal of the power generation unit. The first connection part includes a connector on the vehicle side and a connector on the power generation unit side.

Electrically driven vehicle

In an electrically driven vehicle equipped with a battery usable for running, a power generation unit of engine driven type that charges the battery is detachably mounted on the vehicle including a case where at least an engine of the power generation unit is detachably mounted, and the vehicle includes first stop means for bringing the power generation unit in a stopped state when the power generation unit is installed in or removed from the vehicle, and a generation stop switch for making an operation request to the power generation unit. More specifically, the first stop means stops an operation request signal to the power generation unit through low-voltage system wires when the generation stop switch is ON (no operation request is made).
