- a bolt not shown
- a cam shaft 2 on the upper surface of the cylinder head 1 is rotatably supported by a bearing portion 5 provided integrally with the cylinder head 1 and a bearing cap body 6 fastened to the bearing portion 5 by a pair of left and right bolts 7.
- a portion of the cam shaft 2 adjacent to the bearing portion 5 and the bearing cap body 6 is provided with a rotor 8 having a projection 9 at a phase position where the intake valve or the exhaust valve is opened and closed. ing.
- Reference numeral 10 denotes a cam angle sensor.
- the cam angle sensor 10 is inserted into a through hole 12 in a boss portion 11 provided integrally with the synthetic resin head cover 3, and the tip of the cam angle sensor 10 is positioned on the cam shaft.
- a seal ring 13 is provided on the outer periphery of the cam angle sensor 10 so as to be in close contact with the inner periphery of the through hole 12.
- a mounting portion 14 is integrally provided on a portion of the cam angle sensor 10 outside the head cover 3.
- a metal collar 15 is fixed to a portion of the boss portion 11 of the head cover 3 directly above the bearing cap body 6 so as to penetrate the boss portion 11.
- the lower surface is in contact with the upper surface of the bearing cap body 6, while the lower surface of the mounting portion 14 of the cam angle sensor 10 is in contact with the upper surface of the collar 15.
- a fastening bolt 16 with a head is inserted into the collar 15 from a bolt hole 14a drilled in the mounting portion 14, and the lower end of the fastening bolt 16 is connected to the cylinder head 1 side.
- a female screw hole 17 provided in the bearing cap body 6 and the fastening bolt 16 is fastened in this state, and the lower surface of the boss portion 11 in the head cover 3 and the bearing cap body 6.
- a seal body 18 configured in a ring shape so as to surround the outer periphery of the collar 15 is provided between the upper surface and the upper surface of the collar 15.
- the cam angle sensor 10 can be firmly attached to the bearing cap body 6 on the cylinder head 1 side via the metal collar 15.
- the portion of the boss portion 11 of the head cover 3 and, in turn, the portion near the cam angle sensor 10 can be pressed against the bearing cap body 6 on the cylinder head 1 side to suppress vibration in the portion. Can be supported.
- the cam angle sensor 10 is simply inserted into a through hole 12 provided in the head cover 3 made of synthetic resin, so that heat transfer from the cylinder head 1 to the cam angle sensor 10 can be performed. It can be surely suppressed.
- the above-described embodiment is a case where the bearing cap body 6 that supports the upper half of the cam shaft 2 is used as a member on the cylinder head side for mounting the cam angle sensor 10.
- a member for example, the bearing portion 5 provided integrally with the cylinder head 1 or another component attached to the cylinder head 1 is referred to as a “cylinder head side member” in the claims. It can be used for mounting the cam angle sensor 10.
